Higher or Lower: Solar System Sizes

Compare solar system sizes one pair at a time. Say whether the hidden number is higher or lower, and keep the streak alive as long as you can.

Two entries, one number hidden. Say whether it is higher or lower than the one you can see, and the streak runs until you are wrong.

33 entries to compare, two at a time. Values are km across. Mean diameter in kilometres, covering the Sun, planets, dwarf planets and major moons.
