Crazy factoid one: The Earth masses more than everything else between the Sun and Jupiter combined.

Crazy factoid two: Venus is 80% of the Earth's mass.

It also blows my mind that the Sun accounts for 99.86% of the entire Solar System’s mass.

Makes sense. You have a lot of gaseous outer planets, then a star who's compression needs to be so great that fusion can happen in it. That compression is going to drive up the density of the star.
