The three outer layers of the Sun are its atmosphere; from the inside out. What are the three layers?

The photosphere is the Sun's visible surface. Tip: to help you remember the name, the root "photo" means light, and the photosphere is the part of the sun that we see shining!

The chromosphere is a thin layer above the photosphere that is heated by the energy of the photosphere. Jets of gas may also fly up through the chromosphere. Tip: the root "chromo" means color, and the chromosphere glows red.

The corona is the outermost part of the Sun's atmosphere that flares out millions of kilometers into space. Tip: the word "corona" means "crown" in Spanish, and the corona is the Sun's halo or crown.
