Planet Size Comparison
Textbook diagrams lie about scale. Pick any combination of worlds and see them drawn against each other at their true relative sizes — including the Sun, which dwarfs them all.

How it works
Every circle here is drawn to the same scale, based on each world's real equatorial diameter.
Jupiter is 11 times wider than Earth, which means roughly 1,300 Earths would fit inside it by volume.
Add the Sun to the comparison and the planets shrink to specks — it is 109 Earths wide.
Fun facts
Earth and Venus are near twins in size, just 5% apart in diameter.
Jupiter is more than twice as massive as all the other planets combined.
Mercury is smaller than two of the solar system's moons.
Saturn is so light for its size it would float in a big enough bathtub of water.
