Jupiter has been caught 'kidnapping' comets when they venture too close, forcing them to become temporary satellites of the great planet before they are slingshot away or spiral into Jupiter, according to new data presented at this week's European Planetary Science Congress (EPSC) in Potsdam, Germany.
Comet 147P/Kushida-Muramatsu was captured as a temporary moon of Jupiter in the mid-20th century and remained trapped in an irregular orbit for about twelve years.
