yes and no. first the moon is 3400km this was only 500km. but smaller objects than the moon like Ceres or Pluto are ~spheres. also at that scale the impactors are arguably no longer asteroids but planetesimals. the largest impact is thought to be from a planetesimals 7000km in diameter about the size of mars.

no 6 times is conservative. and one the theia impact was so big that left a sign of the impact 4 billion years later.

That asteroid was a bit, shall we say, BIG!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! About the size of the moon based on its ability to hold a sphere. I could be wrong but I think only about 1 asteroid any where near the size of the moon has ever collided with the earth.

first that comment was 4 months ago. 2nd ... or . . . are both acceptable. just in traditional print the latter is more identifiable as a ellipsis. now that said you need a life more than me man. really, this is sad.
