IC 405 (also known as the Flaming Star NebulaSH 2-229, or Caldwell 31) is an emission/reflection nebula in the constellation Auriga, surrounding the bluish star AE Aurigae. It shines at magnitude +6.0. Its celestial coordinates are RA 05h 16.2m dec +34° 28′. It surrounds the irregular variable star AE Aurigae and is located near the emission nebula IC 410, the open clusters M38 and M36, and the naked-eye K-class star Hassaleh. The nebula measures approximately 37.0′ x 19.0′, and lies about 1,500 light-years away. It is believed that the proper motion of the central star can be traced back to the Orion’s Belt area. The nebula is about 5 light-years across.
