What are the biggest planets?

Answer 1

There are four planets that are called "gas giants" - Jupiter and Saturn, the largest planets, and Uranus and Neptune, smaller but still giants.

Ranked by size:

Jupiter is by far the largest planet in the solar system ; it is so large that every other planet in the solar system could quite easily fit inside it! At the equator it has a diameter of 142,984 km. From pole to pole, however, it is (still an impressive) 133,708km in diameter. This is because it rotates so fast (less than 10 hours!) that, at such a colossal size, the inertia causes it to bulge outwards slightly at the equator.

Saturn has a diameter at the equator of 120,536 km.

Next is Uranus

then Neptune

then Earth

then Venus

then Mars

and finally, tiny little Mercury.
