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
Other planetary systems are systems of planets, moons, and other celestial bodies that orbit around a star other than our own Sun. These systems are also known as extrasolar systems or exoplanetary systems.
As of August 2021, over 4,400 other planetary systems have been discovered. However, it is estimated that there could be billions of other planetary systems in our galaxy alone.
There are several methods used to detect other planetary systems, including the transit method, radial velocity method, direct imaging, and gravitational microlensing. Each method has its own strengths and limitations, and scientists often use a combination of methods to confirm the existence of a planetary system.
While it is possible for other planetary systems to support life, it is currently unknown if any other systems besides our own can support complex life forms. Scientists are actively searching for habitable planets within other planetary systems, but the conditions for life to exist are still being studied and understood.
Other planetary systems are believed to form from a protoplanetary disk of gas and dust that surrounds a young star. Over time, these materials clump together and form planets. The exact process of planetary formation is still being studied and is not fully understood.
