When there is too much space junk in space, it increases the risk of collisions with active satellites, spacecraft, and the International Space Station. These collisions can create more debris and further exacerbate the problem in a cascading effect known as the Kessler Syndrome. This can threaten future space missions and the sustainability of activities in space.
Space junk, or debris, can remain in orbit for varying lengths of time depending on its altitude and size. Smaller debris may burn up in the atmosphere within a few weeks to years, while larger objects can stay in orbit for decades or even centuries. Objects in low Earth orbit (LEO) tend to re-enter the atmosphere more quickly due to atmospheric drag, while those in higher orbits can persist much longer. Ultimately, the lifespan of space junk is influenced by factors like its altitude, size, and the gravitational effects of the Earth.
This can be estimated from the size of the earth and its distance from the sun, and the result is that the sun emits about 2 billion (2 x 109) times as much energy as hits the earth. So as a percentage what the earth receives is pretty small, 5 x 10-8 percent if my arithmetic is right
To calculate weight in space, you would use the formula: Weight in space = Weight on Earth x (gravitational pull of space / gravitational pull of Earth). Since gravitational pull in space is typically much lower than on Earth (about 0.17 times that of Earth), your weight in space would be significantly less. Keep in mind this calculation assumes a constant gravitational pull throughout the region of space you are in.
Space shuttles were built for low earth orbit. Not to goto the moon
none ,there isnt any
i dont realy know
About 35% of the light that hits the Earth is reflected away immediately, back into space. The remainder of the light hits the Earth. Some of it is absorbed or scattered in the atmosphere, and much of it reaches the surface as light. Sunlight that is absorbed by the surface heats the Earth.

yes earth is much different than space because space has no air or water.
No there are no satellites that the space program can reuse. This is why there is so much space and orbital debris in the solar system. Space and orbital debris means space and orbital junk or pollution.

When an object is in space, it is usually acted upon by some form of gravitational force from a large body of which keeps it some form of orbit. In addition to this, Newton's Laws pretty much state "things like to keep doing what they're doing". Space junk has no friction acting upon it to slow it's motion, so will continue to move in an orbital motion around some body in space, and not be pulled back down to say, Earth, because of balanced centripetal forces and whatnot. (Standard stop before the physics gets silly.)
pretty much nothing because its just full of portals and stars and space junk. i dont really know about aliens though. we will find out one day
There is much space debris. Humans have many decayed satellites and probes floating around.
Deserts cover 33% of the land surface on earth.
