As compared to, say, Earth’s moon, it’s trivial. The Death Star in “Star Wars” is 100KM or 120KM in diameter (depends what source you believe) and so has a volume something like 1/250,000th that of the Moon - and of course, as we see, it’s basically a huge building, not a solid object, so its density is a fraction of a terrestrial body.
