Jupiter Captured Comet For 12 Years In Mid-20th Century Sep 16, 2009
An international team led by Dr Katsuhito Ohtsuka modelled the trajectories of 18 quasi-Hilda comets," objects with the potential to go through a temporary satellite capture by Jupiter that results in them either leaving or joining the Hilda group of objects in the asteroid belt. Most of the cases of temporary capture were flybys, where the comets did not complete a full orbit. However, Dr Ohtsuka s team used recent observations tracking Kushida-Muramatsu over nine years to calculate hundreds of... (Science Daily)
Gotcha! Jupiter turned comet into a moon Sep 15, 2009
Asteroids and comets can sometimes be distorted or fragmented by tidal effects induced by the gravitational field of a capturing planet, or may even impact with the planet. The most famous victim of both these effects was comet D/1993 F2 (Shoemaker-Levy 9), which was torn apart on passing close to Jupiter and whose fragments then in 1994. (MSNBC -- Technology)
