Annular eclipses are different from total solar eclipses.
From the ground, the sky does not go completely dark, and looking SAFELY at Moon, you'd see a circle of light surrounding the Moon.
The Sun is about 400 times the size of the Moon and it's about 400 times further away.
In a total eclipse, the Moon matches the Sun's "size" exactly and completely covers it.
In an annular one, the Sun is a little bit closer, so the Moon doesn't hide all of the Sun when it's in front.
