What Happens If A Satellite Falls?
What happens if a satellite falls? If 20,000 satellites were falling to Earth, it wouldn't happen instantly. That's because the satellites' speed and positions in space could make some of them take longer to come crashing down. Luckily for us, when they do finally fall on Earth, a lot of them will get burned up by our atmosphere.
How long does it take for a satellite to fall?
suggests that it would take 31.75 years for the satellite to fall to Earth. However, solar radiation pressure and geomagnetic activ- ity must also be included for a more accurate calculation. Using NASA's Debris Assessment Software 2.0. 2 , the same satellite's orbital lifetime would be just 18 years.
Is it true that satellites are in freefall?
Not much. It now too follows the definition of free fall (neglecting air resistance). Now what if the tangential velocity was really large what happens then? The object goes into an elliptical orbit around the earth.
Do satellites ever fall back to Earth?
Satellites don't fall from the sky because they are orbiting Earth. Even when satellites are thousands of miles away, Earth's gravity still tugs on them. Gravity--combined with the satellite's momentum from its launch into space--cause the satellite go into orbit above Earth, instead of falling back down to the ground.
Will space junk eventually fall to Earth?
“If we look at our statistics, we have about 300 objects per year returning to Earth, burning up in the atmosphere,” said Francesca Letizia, a space debris engineer at ESA, in a podcast on space debris. At 800 km above Earth, it will take about 100-150 years to fall back to Earth.”

How long does it take space junk to fall to Earth?
Debris left in orbits below 600 km normally fall back to Earth within several years. At altitudes of 800 km, the time for orbital decay is often measured in decades. Above 1,000 km, orbital debris will normally continue circling the Earth for a century or more.
Which country has the most space debris?
So to answer the question, it is Russia who has the highest number of space debris till date.
