Epsilon Aurigae, also called Maaz or Almaaz, is a yellow supergiant star forming part of the Auriga constellation.

It is orbited by a binary star which is surrounded by a thick dusk cloud. The dust cloud only creates infrared light.

The dust cloud was originally thought to be the largest star known, before it was later revealed to not be a star. The largest star was later found to be VY Canis Majoris, and even later, WOH G64.
