Not sure if it was suggested but you should be able to get small boost from going around asteroids(NASA used it few times to reach and examine pieces of solar system). You would be just running aorund it and gaining speed(not too much beacuse asteroids are small).

I like.... Hmm just wonder if it would be worth the CPU cycles to implement...

The asteroids in game are like max 8km so there is almost no gravity whatsoever.

I thought about the 'slingshot'-effect, too. Then Light postet the thing about the asteroids that are max. 8 km and I thought: 'right; so let's forget about it'.

But if there were any planets or moons in the game you can actually fly around, then gravity definitely has to be in the game! Remember the game 'Frontier: Elite II' from 1993? The physics in this game were almost perfect. With some expierence you could also get into orbit around a planet or star. I once managed to circle around a planet maybe 15 times before crashing into it (without auto-pilot of course)! ^_^
You could also bounce off the atmosphere of a planet, what was impressive!

The problem with planets or moons - game-wise - is, that if you include them and want players to be able to land on them or have a base on them they have to be very detailed and very big.

Edit:
Funny thing: I just calculated the gravity of an 8km (spherical) asteroid that is completely made of iron. It's just 8.79e-3 m/(s^2) or 0.0009 g (= 0,09% of the earth's gravity). ^^

oh ya, an 8km asteroid can be extremely dense to. you don't know if it supercompressed metal or not. it could have a pretty good bit of gravity.

Most Asteroids in our solar system have a bulk density between 1000 and 4000 kg/m^3 which is less than the density of iron (7874 kg/m^3) with which I calculated before, because
1) they are not made of pure iron, but of ores and rock...
2) they are porose

Here's a chapter about it with a list of asteroids and their density: http://www.lpi.usra.edu/books/AsteroidsIII/pdf/3022.pdf

I don't think there are super-high-density asteroids in our solar system. You could include such a thing for design reasons, but it should be very rare and hard to mine. Plus the gravity has to decrease when the mass of the asteroid gets smaller because of the mining.
