Title: Re: Why won't Pluto collide with Neptune? Post by: mikael on Sep 4, 2013 Pluto small than terrestrial planets and ice-rich composition (neither jovian or terrestrial) Both Pluto and Charon (Pluto's moon) are made of ice-rock. Charon larger than Pluto. Pluto is very cold.
Neptune orbits the Sun precisely three times for every two of Pluto's orbits, which means Pluto is a safe distance from Neptune Charon formed by a giant impact similar to how our moon is thought to be formed. |
