'''NGC 2899''' is a [[planetary nebula]] in the southern [[constellation]] of [[Vela (constellation)|Vela]]. It was discovered by English astronomer [[John Herschel]] on February 27, 1835.<ref name=CSeligman/> This nebula can be viewed with a moderate-sized amateur telescope, but requires a larger telescope to resolve details.<ref name=Bakich_2010/> NGC 2899 is located at a distance of {{convert|1026|±|205|pc|ly|order=flip}} from the Sun and {{convert|7939|±|1|pc|ly|0|order=flip}} from the [[Galactic Center]].<ref name=Stanghellini_Haywood_2010/>
'''NGC 2899''' is a planetary nebula in the [[Vela (constellation)|constellation Vela]] at a distance of nearly 6500 light years.<ref name=Atlas>{{cite web|title=Planetary Nebulae|url=http://www.atlasoftheuniverse.com/plannebs.html|website=Atlas of the Universe|access-date=7 July 2015|archive-url=https://web.archive.org/web/20150923175924/http://www.atlasoftheuniverse.com/plannebs.html|url-status=live|archive-date=23 September 2015}}</ref> It was discovered by [[John Herschel]] in 1835.<ref>{{cite web|last=Seligman|first=Courtney|title=Celestial Atlas NGC Objects 2850-2899|url=http://cseligman.com/text/atlas/ngc28a.htm#2899|access-date=26 October 2013}}</ref>

This nebula has an overall kidney shape that is elongated along an axis from [[West-northwest|WNW]] to [[East-southeast|ESE]].<ref name=Streicher_2010/> The overall topology is bipolar with a significant equatorial structure. This shape is believed to result from a binary star system. The mean expansion rate is {{val|43|to|56|u=km/s}}, with high velocity structures expanding at {{val|110|to|130|u=km/s}}. The core mass of the central star is estimated as {{val|1.2|ul=Solar mass|p=~}}.<ref name=Lopez_et_al_1991/>

The nebula lies within a large cavity in the surrounding medium. This opening has quadrupolar shape with a physical dimension of {{val|14|×|11|u=pc}}. The elongation lies along a [[position angle]] of {{val|37|5|u=°}}, which is aligned with the minor axis of the planetary nebula. This opening was most likely crafted by a fast [[stellar wind]] coming from the central star during its [[asymptotic giant branch]] stage, prior to the formation of a planetary nebula. The shape and filamentary structures suggest the interaction of a binary star system.<ref name=Weinberger_Aryal_2004/><ref name=Aryal_et_al_2009/>

NGC 2899 is a planetary nebula in the southern constellation of Vela. It was discovered by English astronomer John Herschel on February 27, 1835.[6] This nebula can be viewed with a moderate-sized amateur telescope, but requires a larger telescope to resolve details.[3] NGC 2899 is located at a distance of 3,350 ± 670 light-years (1,026 ± 205 pc) from the Sun and 25,894 ± 3 light-years (7,939 ± 1 pc) from the Galactic Center.[2]

This nebula has an overall kidney shape that is elongated along an axis from WNW to ESE.[7] The overall topology is bipolar with a significant equatorial structure. This shape is believed to result from a binary star system. The mean expansion rate is 43 to 56 km/s, with high velocity structures expanding at 110 to 130 km/s. The core mass of the central star is estimated as ~1.2 M☉.[4]

The nebula lies within a large cavity in the surrounding medium. This opening has quadrupolar shape with a physical dimension of 14 pc × 11 pc. The elongation lies along a position angle of 37°±5°, which is aligned with the minor axis of the planetary nebula. This opening was most likely crafted by a fast stellar wind coming from the central star during its asymptotic giant branch stage, prior to the formation of a planetary nebula. The shape and filamentary structures suggest the interaction of a binary star system.[8][9]
