I made a new mod today that reduces the amount of asteroids in space.

You can have a look at the result on the nexus mod page:

Mods like this are 100% essential in my book. I just don't know what HG were thinking when they made intra-planet space full of asteroids as it totally is an immersion killer. And it did not used to be like this, they made it that way after a number of updates and it just 'stuck' like that.
