Effectively zero. It may be attacked by the satellite that you fall.
Although the number of satellites in the orbit has risen in exponential functions, modern satellites have the ability to control the re -entry trajectory, and they are built from low -density materials to burn out as they fall into the atmosphere.
However, fragments in the universe are still reaching the ground. We use the rocket stage from the long March rocket in China as a recent example.
However, in the past 50 years, NASA has recorded average. One of the fragments of the universe that reaches the ground per day Currently, death or serious injury is not known.
One piece per day sounds like a lot, but at least three airplanes are dropped (mainly non -profit aircraft) in order to focus on it. 。
When the plane crashes, it usually remains in one piece until the moment of the impact, and is often full of fuel. As a result, the falling aircraft is much more fatal than a typical cosmic fragment. This may be part of a small titanium and carbon fiber panel.
There is no difference here for the extra altitude that the fragments of the universe have fallen. Falling from 300 km (about 186 miles) is the same as 10 km (6.2 miles) to reach the terminal speed long before hitting the ground.
Aircraft tend to fly near a dense population area, but spaceship is much more evenly distributed around the world. If everyone in the world goes out and spread, they cover only about 0.0002 % on the surface of the earth.
Therefore, even if the fragments of the fallen universe are fatal, they miss 99.9998 % and translate them into one death every 1 or 300 years.
This article is the answer to the question (asked by Charlie Bond by e -mail) “What is the possibility of a falling satellite?”
