The escape velocity from a massive object is the speed needed to reach an infinite distance from it and have just slowed to a stop, that is, to have just enough kinetic energy to climb out of the gravitational potential well and have none left. You can find the escape velocity by equating the total kinetic and gravitational potential energy to zero. Given that consider any gas close to the surface of the Moon at a temperature of the Moon's...

A planet has been discovered around a Sun-like star with an estimated mass of 54.3 times the Earth\'s mass and an estimated radius of 15.1 times the Earth\'s radius. It has been hypothesized that the planet has abundant hydrogen in its atmosphere. In order for the planet to maintain a hydrogen atmosphere for a significant amount of time, the planet\'s temperature must be less than some maximum temperature. Recall that the mass of Earth is 5.97 × 1024 kg and...
