Answer 1

Load up Kerbal, open the cheat window to put any ship into orbit of the sun, turn on infinite fuel/ power.

Now try to crash into anything without opening the map screen.

Bet all you can manage is crashing into the only thing you can see, the sun. Even that’s a whole other problem that takes way too much fuel
