What's with the "Several million years later" context in the transcription?!? The distances might be vast and all, but i doubt the timeframe is ''that'' long... -- [[Special:Contributions/173.245.51.210|173.245.51.210]] | What's with the "Several million years later" context in the transcription?!?

Wikipedia says "A {{w|comet}} is an icy small Solar System body that, when passing close to the Sun, heats up and begins to outgas, displaying a visible atmosphere or coma, and sometimes also a tail." I see no clear suggestion on Wikipedia that a {{w|small Solar System body}} might change from being an asteroid to being a comet each time it passes by the sun and starts to outgas. It seems to me that SSSB's that contain ices and other volatiles that would outgas given enough heat are comets, but I haven't seen that question really addressed clearly by any authoritative sources. For now I'm switching the references to distant comets from "asteroid" to "comet nucleus", which is used on wikipedia and seems like a neutral term for an icy object that would show a cometary atmosphere and tail when close to the sun. Also, the oort cloud is hypothesized to have both a spherical and a disk-like structure, and is part of the solar system. Please discuss further related changes here. Thanks!

:The most false understanding is: A comet is a dirty snowball. In fact it's just a snowy rock, most of it is still rock, otherwise it would break up at a distance between Earth and Venus. And all the frozen gases are not only H<sub>2</sub>O. Furthermore a comet is a comet when we can see its shape, unless that tail is shown it's just a small object at our solar system, not more.--[[User:Dgbrt|Dgbrt]] ([[User talk:Dgbrt|talk]]) 22:17, 1 December 2013 (UTC) | :The most false understanding is: A comet is a dirty snowball.
