Refimprove date June 2011 Asteroid capture can happen when an asteroid approaches a large planetary body . Typically asteroids that approach close enough to a planet are thrown out into space or impact the body. In rarer instances, the asteroid is captured in orbit around the planet ref http www.earthsky.org faq asteroids accretion ref . This is possible with any planetary body given the right conditions. Detailed explanation Asteroid capture happens when an asteroid has enough velocity to keep missing the planet it is falling towards but not enough velocity to escape orbit, in other words, when it reaches a stable orbit around it. Asteroids have natural properties that may lend themselves to be captured. The properties of an asteroid that are most significant to this process are its mass and relative velocity to the planet in question. The mass of the planet is also a key variable, as is the trajectory of the asteroid. An asteroid with too much velocity will pass by the planet with a hyperbolic orbit , shooting it out into space. Asteroids that do not have enough velocity will fall into the planet ... velocity which changes with distance will result in either capture or impact. Asteroid capture by Earth The earth moon system creates a particularly unstable situation whereby the orbit of the asteroid ... to keep an asteroid in orbit above the earth. Effecting capture Spontaneous capture relates to a method whereby an asteroid s velocity is not changed and it is captured by the planet. fact date April 2012 Aerocapture relates to a method of slowing down an object, which could theoretically be an asteroid.
