📏 PLANET SIZES
PAGE 1 OF 5 — COSMIC SCALE
SIZE LINEUP
PLANETS ARE NOT EQUAL
If you lined up worlds from the Sun, you would see a huge range of sizes. Mercury is only a little bigger than Earth's Moon. Earth is cozy compared with the giants. Jupiter is the largest planet, more than 11 times wider than Earth. Saturn is a close second. Uranus and Neptune are smaller ice giants, but still far bigger than any rocky world. Size tells you a lot about how a planet formed and what it is made of.
📏 WIDTH
Jupiter's diameter is about 139,800 km, roughly 11 times Earth's width of about 12,700 km.
