IC 405 (also known as the Flaming Star Nebula, SH 2-229, or Caldwell 31) is an emission and reflection nebula in the constellation Auriga north of the celestial equator, surrounding the bluish, irregular variable star AE Aurigae. It shines at magnitude +6.0.  The nebula is located near the emission nebula IC 410, the open clusters M38 and M36, and the K-class star Iota Aurigae.

The nebula, shown here in the light of the hydrogen emission line H-alpha at a wavelength of 656 nm, measures approximately 37.0' x 19.0', and lies about 1,500 light-years away from Earth. 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.
