Astronomy Fun Facts:

Each of those sunspots in the group is much larger in diameter than the Earth.
Their temperature is lower than the rest of the Sun's surface,
but they only appear dark because the surrounding areas are brighter.
If you could isolate a sunspot at the Sun's distance in space,
it would appear to be about 10 times brighter than the full Moon.
