IC 2149 is a planetary nebula in the constellation of Auriga. It was discovered in 1906 by Harvard astronomer Williamina Flemming on photographic plates. [2] It is a small, bright planetary nebula with something to offer in telescopes of most sizes. [3]

Characteristics

Visually it has an apparent magnitude of 10.6 and an apparent size of 12 arcseconds and like other objects of its class a nebular filter may help on its observation. [3]

Its distance to the Solar System has been estimated to be around 1.1 kiloparsecs, having a total mass of 0.03 solar masses and being thought to have been produced by a low-mass star. [4]

Some authors have proposed the planetary nebula that the Sun will produce will be similar to this one, but smaller. [5]

The central star of the planetary nebula is an O-type star with a spectral type of O(H)4f. [6]
