This week, we talk about Fish, High Castles, the size of things and maths. ---- Math mentioned in the episode. Relative mass Sun: 1.99x10^30 kg Mercury: 3.30x10^23 kg Venus: 4.87x10^24 kg Earth: 5.97x10^24 kg Mars: 6.42x10^23 kg Asteroid Belt: 3.20x10^21 kg (maximum estimation) Jupiter: 1.90x10^27 kg Saturn: 5.68x10^26 kg Uranus: 8.68x10^25 kg Neptune: 1.02x10^26 kg Pluto: 1.30x10^22 kg (included for completeness) The combined mass of everything except the Sun comes to approximately 0.13% of the total. So the Sun does account for 99.86% of the overall mass. The planets and asteroid belt together come to 2.67x10^27 kg. Jupiter makes up approximately 71% of that.
