Jupiter 1991

Bay of Rainbows in blue.

Gamma Delphini

Eta Cassiopeia

The primary star in the η Cassiopeiae system is a yellow dwarf (main sequence) star of spectral type G3V, putting it in the same spectral class as our Sun, which is of spectral type G2V. It therefore resembles what our Sun might look like if we were to observe it from η Cassiopeiae.
