We now offer the Cool It! card game in our Science Store. Cool It! is the new card game from UCS that teaches kids about the choices we have when it comes to climate change.
Sunspots are really, really big. Many sunspots are as big as Earth. Earth never really gets this close to the Sun. We made up this picture with Earth next to sunspots so you could see how big sunspots are.

Sizes of Sunspots

Sunspots are very, very BIG!

Most sunspots could swallow a planet! Many sunspots are as big as Earth! Once in a while, huge sunspots the size of Jupiter show up on the Sun.

Most spots are about 1,500 km (932 miles) to around 50,000 km (31,068 miles) across. The Sun sure is a big place!
