It must be in an orbit around the sun 2 ... 6 - The mass of Charon is so large — and the mass of Pluto is so small — that Charon doesn’t actually orbit the dwarf planet.

In 2006, the International Astronomical Union stripped it of its original classification, after narrowing the definition of a planet to be one that clears its orbit with its gravitational heft.

This process involves two icy bodies briefly merging and then separating, leaving Charon in a stable orbit around Pluto. Unlike traditional collision models, this event challenges previous theor ...

Charon is large in size relative to Pluto, and is locked in a tight orbit ... incidents is increasing as the amount of debris in orbit around the Earth grows dramatically. The Quadrantids might ...

Pluto was last and least of them. An icy dwarf only half the size of the United States, it was on average 3.7 billion miles from the sun. It also has a decidedly strange orbit that was highly ...

The IAU defends the definition based on Pluto’s orbit. Unlike other planets that have a more or less circular, equatorial orbit around the sun, Pluto’s is sharply inclined and highly ...
