Solar system Definition and 311 Threads

Okay, everyone, I know that this is sounds like a set-up question. And that's because it is. But please humor me, because I'm trying to get this straight: A MACHO is passing the solar system at the velocity of .5c. Therefore, the MACHO experiences a time dilation. Its time is slowed by...

I have to solve a problem regarding the minimum velocity required to escape from the solar system while taking into account the gravitational force of the Earth as well as the sun. What I am supposed to do is calculate the velocity of an object after escaping from earth. Then I am supposed to go...

I think it's called "Edna"...anyway, it's named after an inuit goddess and it being called the 10th planet of our Solar System...whatever happened to that Quauar (or however you spell it) planet that everyone was talking about not too long ago? Any information on either of these planets would...

Evening all. My teacher has given us the mass, distance, and gravitational force of every planet in the solar system. we have to work out every planets acceleration, speed, and orbital period. I'm having some trouble with the acceleration. This sshould be a very small number right? I'm using...

Sunless "solar"system Is there such thing as a sunless solar system maybe not called solar but has all of the charicteristics of one minus the sun. Possably a huge object being the gravation force or Dark matter or a mini black hole

I was wonding how out solar system will end. Simple enough

http://www.msnbc.com/news/934038.asp Its similar in that the "Jupiter-like" planet they've viewed in this case is caught in a circular orbit. Most of the planets found in other star systems are in the oval shaped orbit. The oval orbit of large planets tends to wack the smaller ones out of the...

according to CNN anyway... http://www.cnn.com/2003/TECH/space/06/24/mars.moon.ap/index.html funny, since Phobos is "one of the darkest objects in the solar system"! http://www.spaceref.com/news/viewsr.html?pid=9578

Can someone tell me, how fast is our solar system moving in space relative to a static coordinate system in space?

If some of the people that frequent this area of PF could please post their findings and or opinions on this debate I would appreciate the input very much. Did the planets of our solar system form uniformly; basically at the same time, out of the same solar material? Or, did some form sooner...
