Constellation

Throughout the Zelda series, constellations have played a somewhat minor role, but nonetheless have been present.

Cassiopeia
Cassiopeia is a constellation in the night sky which is supposed to resemble a woman sitting in a chair.

Appearances
It appears in Majora's Mask and The Wind Waker in different forms, and has appeared in Ocarina of Time as an actual constellation.

In all three games mentioned, the constellation can be found in the sky at night. In the Wind Waker, Link will actually hear about it. To do so, he must look at it with the telescope on Windfall Island near the man who asks for a picture of the moon. Needless to say, it only appears at night. It also appears in Wind Waker in the form of the Five-Star Isles, which are shaped like the constellation. In Majora's Mask, the constellation can be seen in the form of rocks on a wall of Termina Field.

Orion
Orion is a constellation in the night sky which depicts a man wielding a bow. There are three bright stars which comprise his "belt" and are often referred to as the "Three Sisters."

Appearances
Orion can be seen in the night sky of Majora's Mask, Ocarina of Time, and The Wind Waker.
