Are there any pictures of other planetary systems? Are there any close ones? I think I heard a while back of antoher system with planets..
Its not getting a whole lot of press (maybe when its about time to launch it) but it may be the most important project NASA has ever done.Originally posted by Nereid

To the best of my knowledge there has been evidence of other planetary systems found. None are close enough to get actual images, generally the only evidence is irregularities in motion of a star which can only accounted for by orbiting bodies. None are very close.

I have a question. What about Planet X that scientists bragged over a while ago -l- was that just a publicity stunt to get our attention?

Many hundred Edgeworth-Kuiper Belt objects have now been found, the largest of them is nearly the size of Pluto. It's clear that Pluto-Charon is just another EKB object, and the principal reason it's still called a planet is historical nostalgia. Several binary EKB objects have been found, so Pluto-Charon is not unique in this respect either.Originally posted by Eepl
Last I heard about the planet X thing they did find an object out there, but scientists said that it was too small for a planet, so they decided to call it an astroid. Pluto was also going to be considerded an astroid, but it had a moon so they kept it as a planet.
And about the first question, I don't know if scientists have found anything, but scientists say that mathimatically there has to be solar systems like ours.
Am not quite sure what you're asking here, so the following may miss the mark:Originally posted by Loren Booda
Have there yet been found (or even theorized) two or more mutually orbiting planetoids free of stellar gravitation?

more than two objects of approximately the same mass cannot exist in a stable orbital configuration. Of course, a massive parent with many low-mass satellites is a stable configuration. - Nereid
