IC 2149 is a planetary nebula in the constellation of Auriga. It was discovered in 1906 by Harvard astronomer Williamina Flemming on photographic plates.{{Cite web |title=Index Catalog Objects: IC 2100 - 2149 |url=https://cseligman.com/text/atlas/ic21.htm#ic2149 |access-date=2025-02-17 |website=cseligman.com}} It is a small, bright planetary nebula with something to offer in telescopes of most sizes.http://observing.skyhound.com/archives/jan/IC_2149.html Skyhound
Characteristics
Visually it has an apparent magnitude of 10.6 and an apparent size of 12 arc seconds and like other objects of its class a nebular filter may help on its observation.
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.{{cite journal

Some authors have proposed the planetary nebula that the Sun will produce will be similar to this one, but smaller.{{cite journal

The central star of the planetary nebula is an O-type star with a spectral type of O(H)4f.{{cite journal|doi=10.1051/0004-6361/202141916|title=Planetary nebulae in Gaia EDR3: Central star identification, properties, and binarity|year=2021|last1=González-Santamaría|first1=I.|last2=Manteiga|first2=M.|last3=Manchado|first3=A.|last4=Ulla|first4=A.|last5=Dafonte|first5=C.|last6=López Varela|first6=P.|journal=Astronomy & Astrophysics|volume=656|pages=A51|arxiv=2109.12114|bibcode=2021A&A...656A..51G|s2cid=237940344}}
