What people know about space.
There is a lot that people know about space! Here are some interesting facts:
1. The universe is estimated to be around 13.8 billion years old.
2. The Earth is one of eight planets known to support life.
3. The largest planet in our solar system is Jupiter, which is more than 1,000 times the size of Earth.
4. The farthest human-made object from Earth is the Voyager 1 probe, which is over 14 billion miles away.
5. The International Space Station orbits the Earth at an altitude of around 250 miles.
6. The first person to walk on the moon was Neil Armstrong, who stepped onto the lunar surface on July 20, 1969.
7. The Hubble Space Telescope has captured stunning images of galaxies, stars, and other celestial objects.
8. The Mars Curiosity Rover has been exploring the surface of Mars since 2012.
9. The Cassini mission discovered several moons orbiting Saturn, including Enceladus, which has a liquid water ocean beneath its icy surface.
10. The Event Horizon Telescope project created the first-ever image of a black hole, which is located in the center of the galaxy M87.
Some additional details about space:
1. Space is vast and infinite, with an unknown number of galaxies beyond what we can observe.
2. The universe is still expanding, and scientists believe it will continue to do so indefinitely.
3. The cosmic microwave background radiation, which is thought to be left over from the Big Bang, is found throughout the universe.
4. Dark matter and dark energy are believed to make up a large portion of the universe, but their composition is still unknown.
5. Gravity is the weakest force in the universe, but it is also the most pervasive, affecting everything from the motion of planets to the behavior of galaxies.
6. Time dilation occurs when objects move at high speeds relative to each other, causing time to appear to slow down for the moving object. This effect becomes more pronounced as the speed approaches the speed of light.
7. Black holes have such strong gravity that nothing, not even light, can escape once it falls past the event horizon. They come in various sizes, ranging from small ones with the mass of a few suns to supermassive ones found at the centers of galaxies.
8. Wormholes are theoretical shortcuts through spacetime that could potentially connect two distant points. However, they are still purely speculative and have yet to be observed or proven.
9. The Fermi Paradox suggests that if advanced civilizations exist elsewhere in the universe, we should have seen some sign of them by now. It remains a topic of debate among scientists and philosophers alike.
10. The search for extraterrestrial intelligence (SETI) continues to this day, using various methods to detect signs of intelligent life elsewhere in the universe. So far, no definitive evidence has been found.
People don't know about space.
There are many things that people may not know about space, including:
1. The universe is constantly expanding, and the rate of expansion is accelerating.
2. The universe is estimated to be around 13.8 billion years old, based on observations of the cosmic microwave background radiation.

These are just a few examples of what people may not know about space. There is always more to learn and discover about the vastness of the universe.
How much the space is far away from earth
The distance from Earth to space varies greatly depending on where in space you are referring to. Here are some approximate distances to different locations in space:
* The Moon: About 239,000 miles (384,000 kilometers)
* The International Space Station: About 250 miles (400 kilometers)
* Low Earth Orbit (LEO): About 100 miles (160 kilometers)
* Geostationary Orbit (GEO): About 22,000 miles (35,000 kilometers)
* The Edge of the Solar System: About 10 billion miles (16 billion kilometers)
* Other Planets:
+ Mercury: About 36 million miles (58 million kilometers)
+ Venus: About 67 million miles (108 million kilometers)
+ Mars: About 140 million miles (225 million kilometers)
+ Jupiter: About 483 million miles (778 million kilometers)
+ Saturn: About 886 million miles (1.4 billion kilometers)
+ Uranus: About 1.7 billion miles (2.7 billion kilometers)
+ Neptune: About 2.7 billion miles (4.3 billion kilometers)
Keep in mind that these distances are approximate and can vary depending on the specific location within the given body. Additionally, the distances between objects in space are often measured in astronomical units (AU), which is equal to the average distance between the Earth and the Sun. One AU is about 93 million miles (149.6 million kilometers).
Is it possible to see the International Space Station (ISS) from earth with naked eyes:
No, it is not possible to see the International Space Station (ISS) with the naked eye from Earth. The ISS is a relatively small object in space, and its apparent magnitude (brightness) is too low to be visible to the unaided human eye.
The ISS is typically about 250 km (155 miles) above the Earth's surface, which means it appears as a tiny dot in the sky. To put that in perspective, the full moon, which is about 384,000 km (239,000 miles) away, appears as a disk about 30 arcminutes wide in the sky. That's equivalent to holding a US penny about 1 foot (30 cm) away from your face and covering it with a nickel. You wouldn't be able to see the ISS without binoculars or a telescope because it is simply too small and too far away.
However, there are certain times and places where the ISS may be visible to the naked eye under ideal viewing conditions. For example, during a flyover of a major city, the ISS may pass close enough to the horizon that it can be seen with the naked eye for a short period of time. But these sightings are rare and usually only last for a few seconds before the ISS disappears behind the curvature of the Earth.
What is the speed of ISS rotation:
The International Space Station (ISS) rotates at a rate of about 1.5 times per minute, or 90 degrees every four minutes. This rotation is necessary to maintain a comfortable living environment inside the station, as well as to provide a stable platform for scientific experiments and other activities.
The ISS is equipped with a set of gyroscopes that help maintain its orientation and stability. These gyroscopes use a combination of reaction wheels and moment gyros to keep the station spinning at a constant rate. The rotation of the ISS creates a pseudo-gravity effect known as "weightlessness," which allows astronauts to move around and perform tasks more easily than they would in microgravity environments.
In addition to providing a comfortable living environment, the ISS's rotation also helps to distribute the load evenly among the station's systems and components. It also plays a role in the station's attitude control, ensuring that it remains properly aligned with the Earth and the Sun throughout its orbit. Overall, the ISS's rotation is a critical aspect of its design and operation, and it requires careful management and monitoring to ensure the safety and success of its missions.
What speed the ISS moving along orbit:
The International Space Station (ISS) moves at a speed of approximately 27,600 km/h (17,160 mph) relative to the Earth. This is because the ISS is in a low Earth orbit (LEO), which means it completes one orbit of the Earth every 90 minutes.
To give you an idea of how fast that is, consider that a commercial airliner typically cruises at speeds ranging from 800 to 900 km/h (500 to 560 mph). So, the ISS is moving almost three times faster than a typical airliner!
It's worth noting that the ISS's speed can vary slightly over the course of its orbit due to the gravitational influences of the Earth and the Moon, as well as atmospheric drag. However, the ISS's speed is carefully controlled and monitored by mission controllers to ensure that it stays within a narrow window of acceptable values.
Why China made it's own space station:
China has been actively pursuing space exploration and development since the 1950s, and the construction of their own space station, called Tiangong ("Heavenly Palace"), was part of that effort. The Chinese government saw the development of a space station as a way to further their goals in space exploration and to demonstrate their technological prowess.
Tiangong was launched in 2011 and served as a testbed for various space-based technologies such as docking, life support systems, and navigation. It also provided a platform for conducting scientific research in space, including experiments related to materials science, biology, and physics.
China's space program has been expanding rapidly in recent years, and the country plans to establish a permanent manned space station by 2022. This new space station, called Taiyang Shili ("Great Hope"), will serve as a base for long-duration spaceflights and will be capable of accommodating both Chinese and international crews.
Overall, the development of China's space station reflects the country's growing ambition and capabilities in space exploration, and demonstrates its commitment to advancing scientific knowledge and promoting cooperation in space.
If we hit a ball in the space towards the sun what will happen:
If a ball were somehow propelled into space towards the sun, it would likely experience a number of effects due to the intense gravitational forces present near the sun. These effects would depend on a variety of factors, including the initial velocity and trajectory of the ball, the density of the ball, and the specific conditions surrounding the encounter.
Some potential outcomes that might occur if a ball were thrown into space towards the sun include:
1. Gravitational attraction: As the ball approaches the sun, it would be pulled towards the sun by the sun's gravitational force. The strength of this force depends on the mass of the sun and the distance between the ball and the sun. The closer the ball gets to the sun, the stronger the gravitational pull would become.
2. Heat and friction: As the ball approaches the sun, it would begin to heat up due to the intense radiation emitted by the sun. The ball would also experience significant frictional heating as it interacted with the hot plasma surrounding the sun.
3. Atmospheric entry: Depending on the initial velocity and trajectory of the ball, it could potentially enter the sun's atmosphere and burn up upon impact. Alternatively, it could collide with the sun's corona or chromosphere, producing spectacular auroral displays.
4. Orbital insertion: In some cases, the ball could be inserted into an orbital path around the sun, allowing it to circle the star like a natural satellite. This scenario would require careful planning and precise control of the ball's initial velocity and trajectory.
5. Escape from the solar system: If the ball were traveling at a sufficient speed and had enough momentum, it could potentially escape the gravitational influence of the sun and continue on a hyperbolic trajectory through interstellar space.
It's important to note that these scenarios are highly dependent on the specific circumstances of the encounter and are subject to a range of variables and uncertainties.

Voyager 1 was launched on September 5, 1977, by NASA from Cape Canaveral Air Force Station in Florida. It was designed to study the outer Solar System and beyond, with a primary mission to fly by Jupiter and Saturn and send back data about these planets and their moons. The spacecraft was equipped with a range of scientific instruments, including cameras, spectrometers, and magnetometers, which allowed it to gather valuable data about the interplanetary medium and the planetary systems it encountered.
One of the most significant achievements of Voyager 1 was its ability to continue operating for an extended period after leaving the heliosheath, the region around the Sun where the solar winds slow down and become less intense. This allowed the spacecraft to collect data on the interstellar medium, which is the material that fills the vast distances between stars. In addition, Voyager 1 became the first human-made object to leave the Solar System, entering interstellar space in August 2012.
Voyager 1 has also made several other notable achievements during its journey. For example, it discovered the largest moon of Saturn, Titan, and sent back stunning images of the rings of Saturn and the moons of Uranus. Additionally, it provided valuable insights into the structure and composition of the asteroid belt, which lies between Mars and Jupiter.
Overall, the achievements of Voyager 1 have greatly expanded our understanding of the Solar System and the interstellar medium. Its continued operation long after leaving the Solar System has enabled scientists to learn more about the universe than ever before, making it one of the most successful missions in the history of space exploration.
