A minor planet or planetoid

Answer 1

Minor Planets

The term minor planet is still used, but after reclassification in 2006 these are now generally referred to as dwarf planets. Dwarf planets orbit the sun, but are not satellites, that is to say that they do not orbit another planet, since then they would be classified as moons. They are big enough to hold an ellipsoid shape under their own gravity (like a squashed sphere), but have not cleared their orbit of other objects. That is to say that at the same distace out, there is a significant amount of other matter that is not part of the dwarf planet.

Answer 2

Simply, a Minor Planet is any object in orbit around our Sun that is not a Planet, Dwarf Planet, or a Comet.

Prior to 2006 every object in orbit around our Sun was either a Planet, a Minor Planet or a Comet. However, when the issue of Pluto's planet-hood was raised that year, a new term, Dwarf Planet, was introduced.

Since then, the most well known Minor Planets were reclassified as Dwarf Planets, leaving behind only a few Minor Planets that anyone ever hears about. But as a category they are numerous, with more than 540,000 officially known to date.

Answer 3

Asteroids. Sometimes Dwarf planets are called minor planets also.

Answer 4

Minor planets are any objects that aren't comets or planets that revolve around the sun. Asteroids, Trojans, centaurs, and dwarf planets are classed as minor planets.

Answer 5

A minor planet, or dwarf planet, is a object that orbits the Sun but is not classified as a planet. Examples include Pluto and Ceres.

Answer 6

Asteroids. (Recent changes in definitions mean other things, such as dwarf planets, are now called minor planets also.)
