I thank God, too, that I am not blind.
I'm confused about all of the concern about vision this morning, but if you are all thanking God, then I'll join in. Thank God for making all of this matter in all of its forms, even compressed.
The volume of a sphere with a 3km radius is 113.1 km3; the volume of a sphere with a 30km radius is 113,097 km3. That would make it more like 1,000 times the volume.
10 x volume (1131 km3) would be a radius of 6.46 km.

Typically, the most sought after characteristic of a planet is its habitability. A habitable planet has liquid water on its surface, explained Margaret Turnbull of the Carnegie Institute of Washington. Thus far, 90% of all detected alien planets have host stars that can flare and sterilize the surface of the planet. Furthermore, planets, which are that close to their host star, would be in a synchronous orbit. This means that only one side of the planet would face the host star and all potential water on that side would evaporate and go to its "dark" side.
