Welcome to Physics Forums. Asteroid velocity What is terminal velocity for an asteroid ? The mass of Ceres is 1/100, or 0.01 of the Moon's, and its diameter compared to the Moon's is 290 miles/1080 miles, or 0.269. Dividing mass by radius (0.01 divided by 0.269) gives us 0.037. Converting that answer to feet gives almost 1478 feet per second, the escape velocity at Asteroid Ceres. Once escape velocity is achieved, no further impulse need be applied for it to continue in its escape. A velocity that results in a jump of 1 meter height can never be equal to the escape velocity, which produces a jump of infinite height. Perhaps you mean the velocity that would produce a 1 m jump height under different conditions -- but we need to know what those conditions are. m 2 /kg 2. Also later to get escape from Saturn parameters from Saturn''s moon Titan. p.s. Please select a … Calculates the escape velocities from the planet and from the solar system. 2008-Mar-03, 02:41 PM #2. This is a simple logical fact. Imagine that asteroid A that has an escape velocity of 50 m/s. MeteorWayne . Its value for the Earth is 11,200 m/s. And, what is the speed of the current fastest travelling asteroid ? A particle will escape if it has a “one-time” vertical component of velocity greater than this value. As a double check, we can compute Ceres' escape velocity in reference to the Moon. View Profile View Forum Posts Member Join Date Jan 2007 Posts 35. In other words, if given escape velocity, the object will move away from the other body, continually slowing, and will asymptotically approach zero speed as the object's … ... between Lunar escape velocity and the minimum velocity that would allow correctly aimed debris to leave Earth''s vicinity). Asteroid Speeds Not sure what you mean by terminal velocity. Find escape velocity, surface gravity, mass of different solar system objects, planets, moons, comets, asteroids, centaurs, kuiper belt objects and more. If asteroid B has twice the mass and twice the radius, it would have an escape velocity - 14297933
