added picture...if anyone can find a better one, that might be a good idea. I'm sure there are better ones out there somewhere. --ScottyBoy900Q∞ 02:13, 08 Oct 2004 (UTC)
Should PSR B1257+12's 3 light major planets [1] (http://pr.caltech.edu/media/Press_Releases/PR12402.html) be included? - Jeandré, 2003-06-06t20:52z

Intro needs clarification: Are they considered a part of Solar System, if not, how close need they be? Because when I first saw the word, I though it's any planet not in the Solar System, like those from other constellations. --Menchi 23:28 12 Jul 2003 (UTC)

several million extrasolar comets have also been detected.
I never heard of those. Detecting comets should be much harder than detecting planets. I am tempted to remove this sentence, unless it's backed by some reference source. At18 19:25, 21 Aug 2003 (UTC)
- I did a bit of research, and found that many comets have been indirectly inferred. Of course they haven't directly detected - too faint. I'm changing the sentence wording to reflect this fact. At18 21:21, 21 Aug 2003 (UTC)
Pulsar Planets
[2] (http://www.space.com/scienceastronomy/aas_earthsize_020329.html)
This op-ed piece in the introduction about pseudo-planets that Wolszczan discovered is very very opinionated. There is currently no definition for planet. So any sub-brown-dwarf accretion large enough to be thought of as a planet, that orbits a star, is a planet. The hooey about pulsar planets not being real planets is chauvinistic crap.
If you use the disk-instability model to make giant planets, according to some opinins, these aren't planets either, as a 'real' planet is formed by core accretion, and disk-instability only forms brown-dwarfs.

I removed the space telescope part of this sentence:
"Planets orbiting main sequenece stars were not discovered until the 1990's, when new space telescopes good enough were constructed."
and rewrote the surrounding paragraph. -Wikibob | Talk 16:46, 2004 Aug 7 (UTC)
Planet naming
- see Wikipedia_talk:WikiProject_Astronomical_objects#Extrasolar_Planets; there needs to be a default convention on naming the articles. 132.205.15.43 05:13, 25 Mar 2005 (UTC)
