What is Plutoid?
1.
Celestial bodies in orbit around the sun at a distance greater than that of Neptune that have sufficient mass for their self-gravity to overcome rigid body forces so that they assume a hydrostatic equilibrium (near-spherical) shape, and that have not cleared the neighborhood around their orbit.
Person 1: "So what are some plutoids?"
Person 2: " Pluto and Eris are the only known plutoids. Ceres is between Mars and Jupiter, so it is NOT a plutoid."
Person 1: "Whatever. The International Astronomical Union (IAU) is crazy anyway. Who uses this stuff?"
