Okay, after a quick format of a spreadsheet and a little information from the wikipedia I came up with the following-- Planet/Actual Gravity/Gravity acording to GURPS/Gravity acording to home-brew Mecury/0.38/0.38/0.38 Venus/0.90/0.90/0.89 Earth/1.0/1.0/1.0 Mars/0.38/0.38/0.38...

Ooooooh, project time! Be right back. . .

Hello, qrall and thanks! Very good reference indeed! Just need to refine my search a bit--first searched turned up 527,000 hits, but I've gotten it down to about 8,000 (using SAO/NASA). Just a little more fine tuning to go.

Centrifugal force always tends to flatten things doesn't it? I would assume galaxies to be flat due to that force.

The space around us is littered with class M stars. At a certain distance they thin and eventually stop altogether. The galaxy is still filled with class M stars, it's just they are too dim to be seen past a certain distance. We don't see a mass of stars because they are so distant from us...

Gives you a nice idea of how insignificant we are don't it?

Way back in the day when in elementry school we were taught the planets could be divided into two groups, the inner terrestrial planets and the outer jovian planets. Hard for me not to think of the outers as something other than jovians. And as FtlIsAwesome said, I too am under the impression...

I've sent a private message or two FtlIsAwesome's way regarding this topic, and we're curious as to your opinions. Here is the original message I sent him-- So, thoughts and comments?

Don't get me wrong, I love these pictures. I could never come close to producing anything like these. But, isn't the sun way to large and overly bright in the images? Uranus is 19.2 AU's from the sun (rougly 2.8 or 2.9 billion km away); shouldn't the sun be just another dot in the sky among...

Actually TechNoir, you have a point. The only reason Juipiter gives off more energy than it receives is due to the pressure it's under due to it's own mass. When the sun becomes a red giant, Juipiter will lose a lot more of it's atmosphere than it does now. So by the time the sun is a black...

Here we go, I found the article. It's the Canis Major Dwarf Galaxy we're bumping into: http://www.universetoday.com/22828/milky-way-collision/" . Sorry for the added post, I thought I had hit the "edit" button of my previous post. I kind of like "Milkomeda" for the name of our future...

I seem to recall reading somewhere (a few years ago) that our Milky Way is currently colliding with a "mini-galaxy." If I recall correctly, it was not of sufficent mass to affect our galaxy but the mini-galaxy would be "gobbled up" (I think was the term the article used) by our own.

Juipiter actually gives off more energy than it receives from the sun. I'm not sure about the other jovians.

Hello, Drakkith. Was there an estimate on how much mass was lost from the belt zone? It's only a guess, but I suspect it would be a considerable amount (based on the guess that the mass present in the belt zone would not have been much different from the mass present in the orbits of each of...

Good evening, everyone. My name is Steve, I'm 37 and from a small town called Fort Dodge in Iowa (USA). I have no formal education in Astronomy, but have always loved the topic since I was a child (most likely due to having a cousin who was an engineer for NASA who would send me photos and...
