Document Summary
Introduction: beyond neptune are million of icy bodies called trans-neptunian objects (tnos). Pluto is one of them, and eris, makemake, and haumea (all dwarf planets) When pluto changed over from a planet to a dwarf there was much commotion for their termed it a plutoid: a celestial object that satisfies three conditions: It orbits around the sun at an average distance greater than neptune. It is massive enough that its own gravity beings it to equilibrium, making it near-spherical. It has not cleared the neighborhood around its path from other orbiting debris. Pluto: tombaugh used a blink comparer, 1930 he discovered it but it was not as large as they thought. It swings inside the orbit of neptune sometimes: the planets will never collide though, very cold. 50k (-223: best guess at the interior. Frozen nitrogen, water icce, mic of silicate rock and water ice.
