Ok, I understand.

Also, when you try to create planet with those propeties in Universe Sandbox^2, the planet will automaticly blow up due to too high dense. :v

Here's one more:

-You start a campfire but it expands out and starts a wildfire, so you send the piece of land to the KSP Space Center and then it explodes all of the rocket fuel.

The End

How to delete planet in KSP:

- Build a machine, which is standing on the chosen body.

- Machine must have a grabbing unit (you use it to grabb asteroids)

- Under 1st grabber build machine with another grabber and can fly upwards (two grabbers must be able to meet each other).

- Put capsule with Kerbal somewhere.

- Kerbal leave the capsule and walk into 2nd grabber.

- Decouple 2nd machine and fly to the 1st grabber.

- Kerbal on 2nd grabber colide with 1st grabber.

- PROFIT. Game don't know what to do.

- Planet is removed.
