Sunspots are BIG!

Below is a picture of the sun taken by SOHO on September 23, 2000.
Look carefully at the biggest clump of sunspots, near the middle of the disk of the sun. 2000-09-23 Sun image by SOHO

This next picture shows a close-up of that big group of sunspots.
The picture also shows the size of the Earth as if it were right next to the sunspots. 2000-09-23 Sunspot group compared to the Earth

The littlest sunspot you can easily see in your Flip Book is as big as the whole Earth!
