The moon is 3,474 km in diameter. Getting hit by an asteroid 1,000 km in diameter would do a lot of damage, far more than leaving a crater. You’d think it would have blown the moon to bits. Of course, if they have the same density, then the object that hit the moon would have a mass (1,000/3,474)^3 or 2.4% of the moon’s mass.

That made me scratch my head too. I would guess 1000m, not 1000km!

The 1,000 km size is in reference to the impact basin’s size, not the asteroid, which was about 40 miles across according to Wiki.
