| | Solar system (Site not responding. Last check: ) |
 | | In broad terms, the solar system consists of the Sun, eight bodies in relatively unique orbits (commonly called planets or major planets) and two belts of smaller objects (which can be called minor planets, planetoids, meteoroids, planetesimals or, in the case of Pluto, planets). |
 | | In the outer regions of this solar nebula, ice and volatile gases were able to survive, and as a results, the inner planets formed minerals and are rocky, and the outer planets were massive enough to attract gases. |
 | | Before the discovery of 2060 Chiron and the trans-Neptunian objects, the term "minor planet" was a synonym for asteroid, but many people now prefer to restrict the use of "asteroid" to refer to rocky bodies of the inner solar system. |
