Approximately 11.2 Kilometers per second, or about 33 times the speed of sound.
However, at about 9000 kilometers above the earth, it is slightly less than 7.1 kps.
i think you mean atmosphere they normally go about 200,000 miles an hour when leaving earths atmosphere
To be able to escape earth's atmosphere you need to achieve a velocity that is great enough to achieve sufficient energy to escape the earth's gravitational field strength.
Astronauts travel in space and escape earth's atmosphere by wearing gravity resistant suits and traveling to outer space in a space shuttle that is insulated against the elements.
No. To even reduce it by 75% you must travel out to 4000 miles.
About thirty times the speed of sound, Mach 30 approx.
No it can't.

The heaviest ones.
escape the gravitational well and if the planetoid has one, the atmosphere.
The speed at which a rocket must travel to escape the gravitational pull of the earth is 25,000 miles per hour.

8km/s
Too light and too close to the 1/6 rule in escape speed from earth's gravity. A gas must be withing 1/6 of the escape speed from earth's escape speed for it's gravity to be easily retained in the earth's atmosphere. These two gases are heated too easily. are too light and too close to the escape speed to hang around unfixed, or untrapped in the atmosphere.
