Is libration a process? The HAT-P-1b article says circularization is caused by tidal forces.--Gbleem 20:10, 16 September 2006 (UTC)

[edit] Short-period planet
I have redirected the above (w and wo hyphen) to this page. I'm assuming that the terms are essentially synonyms. A planet in a short period must necessarily be massive to avoid being torn apart(?). If there is some differentiation between the two terms, the redirect can be made its own article. A quick look at google scholar shows both terms in use in research papers.

[edit] Comparatives & Sentence Structure
I've got a stylistic question about this sentence:
"In comparison, a Hot Jupiter is about eight times closer to its star than Mercury is to the Sun."
Does WP have a style guide instruction for this sort of issue? I've seen these comparisons made with greater frequency both on WP and on other web sites.
The comparison is confusing because the word "times" indicates a mathematical increase in distance but "closer" indicates a mathematical decrease in distance. So it doesn't really mean anything.
This might mean that Mercury is eight times farther away from the sun than a Hot Jupiter is from its star. Or it might mean that Hot Jupiter planets are one-eighth or about 12% the distance that Mercury is.
But maybe it's something else; I have to guess about the real meaning.

I understood it when I first read it, but now that you point it out, the language is somewhat confusing. You can tell from the context that they mean hot Jupiters orbit at about one eighth the distance from Mercury to the sun (about 0.05 AU, versus Mercury's orbit of approximately 0.383 AU). I have changed the wording of the sentence to clarify its meaning. (Colinsweet 11:37, 3 August 2007 (UTC))
[edit] Capitalization
In both of the external links, the format of the capitalization is "hot Jupiter" (unless, of course, it is at the beginning of a sentence or as in the title of the article). I changed the capitalization to be consistent with this format.(Colinsweet 12:28, 1 August 2007 (UTC))
[edit] First hot jupiter
Info about first known hot jupiter (and for that matter statistic and actual records in mass, size, or distance) is nowhere in article. This is obvious thing to do! --84.10.180.181 (talk) 10:47, 23 December 2007 (UTC)
