Why is Charon not a planet?
If it were not orbiting Pluto, Charon would be a dwarf planet in its own right. It may yet be determined a dwarf planet, particularly because it doesn’t orbit Pluto – instead, the two worlds orbit a common centre of gravity. As they move, they keep the same face toward each other because they are tidally locked.

Can humans live on Ceres?
A ‘Megasatellite’ Orbiting Ceres Would Make a Fine Home For Humans, Scientist Says.

Why is Pluto not a planet?
Answer. The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet. Essentially Pluto meets all the criteria except one—it “has not cleared its neighboring region of other objects.”

How are moons different from planets?
There is a very basic difference between the two: A planet revolves around the Sun and a moon orbits a planet. Technically, the moon also orbits the Sun as it spins around its planet, but because it has its own sub-orbit of a planet scientists define it as a moon.
