This website lists some of record breaking feats of the planets, and moons of our solar system .

Tallest mountain for each planet, biggest crater, longest days,

As we all know the ten known planets of solar system are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto and the recently discovered 2003 UB313, which obviously I have no record breaking information on as it has not been explored in sufficient detail yet

Here is my list of record breakers
