WebThere are two primary factors: size and distance from the Sun. Gravity helps planets and moons to hold on to their atmospheres, so small planets/moons such as Mars and the Moon have thin atmospheres. Also, if you are closer to the Sun, the atmosphere is hotter and the molecules are moving faster and so can reach escape velocity. WebDec 19, 2024 · A "dwarf planet" is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, (c) has not cleared the neighbourhood around its orbit, and (d) is not a satellite. notnull in entity class

WebMar 31, 2024 · The Short Answer: To weigh a planet, scientists need to know two things: how long it takes objects to orbit the planet and how far away those objects are from the planet. The time it takes an object to orbit a planet depends on its distance from the planet and the planet’s weight. In real life, we can’t pick up a planet and put it on a scale.
