NGC 6886 is a planetary nebula in the constellation Sagitta. It was discovered by Ralph Copeland on September 17, 1884.{{cite web|last1=Seligman|first1=Courtney|title=NGC Objects: NGC 6850 - 6899|url=http://cseligman.com/text/atlas/ngc68a.htm|access-date=22 August 2015}} It is {{convert|4.6|±|1.0|kpc|kly}} distant from Earth, and is composed of a hot central post-AGB star that has 55% of the Sun's mass yet 2700 ± 850 its luminosity, with a surface temperature of 142,000 K. The planetary nebula is thought to have been expanding for between 1280 and 1600 years.{{Cite journal | doi=10.1051/0004-6361/201731788 | bibcode=2018A&A...609A.126S| title=Expansion patterns and parallaxes for planetary nebulae| year=2018| last1=Schönberner| first1=D.| last2=Balick| first2=B.| last3=Jacob| first3=R.| journal=Astronomy & Astrophysics| volume=609| pages=A126| doi-access=free}}
