why there is no atmosphere on moon? is there something related to escape velocity.

Asked by ADITYA KUMAR SINGH 2nd March 2013, 4:58 PM

If we calculate the escape velocity on moon's surface it comes as a small quantity which is much less(2.3 km/sec)  than the average (thermal )molecular speed of gases on moon  therefore, there is no atmosphere on the moon.
