Earth
Humanity's homeworld. Most likely the planet on which you currently reside. Also the most lazily named planet other than our moon (Called the moon) in the Solar system as well as also being inaccurate since most of the surface is water, might as well call it planet water.
Mostly Harmless (if you're a human).
In Warhammer 40,000
In the grim darkness of the far future, Earth is known only as Terra or Holy Terra. It is still the homeworld of humanity and the capital of the Imperium of Man, and location of the Golden Throne and the God-Emperor of Mankind. Pretty much the best place to be, unless you're some sort of heretic that doesn't like gold-plated everything.
The single thrill of excitement the planet got was when Horus turned up in orbit. But instead of bringing potato salad for the annual family bbq, he brought a lot of PAIN and daddy issues to work out and promptly invaded the world in an attempt to end the Heresy one way or the other. Of course the game won't be what it is if he had just won there and then, so the Big E offed him and evaporated his soul right after sustaining near-mortal wounds.
There is so much awesome shit on Holy Terra that most of the planet is practically a cross between a museum and an amusement park. Of course, grimdark means the lines are so long they're measured not in hours but in generations and by the time you would have reached the front of the queue the whole purpose of visiting might have completely been forgotten.
Currently the Tyranid hive fleets are en route to Terra, drawn to the Emperor and his psychic lighthouse. Like Horus, they will not be bringing a fruit basket to visit, though they are expecting one hell of feast when they arrive.
