'''NGC 5882''' is a small<ref name=OMeara2013/> [[planetary nebula]]<ref name=Pottasch2004/> in the southern [[constellation]] of [[Lupus (constellation)|Lupus]], positioned about 1.5° to the southwest of the star [[Epsilon Lupi]].<ref name=Sinnott1997/> It was discovered by English astronomer [[John Herschel]] on July 2, 1834 from the [[Cape of Good Hope]] observatory.<ref name=OMeara2013/> [[John Louis Emil Dreyer|John L. E. Dreyer]] described it as "very small, round, quite sharp".<ref name=cseligman/> It is located at a distance of approximately {{convert|2.362|kpc|kly|1|disp=out|abbr=off|lk=on}} from the [[Sun]].<ref name=Stanghellini2008/>

This nebular region consists of the cast-off outer atmosphere of an aging star. It is roughly elliptical in shape with several clumps of ionized material, and is surrounded by a larger region of low-level emission that extends for three times the nominal diameter of the main nebula.<ref name=Pottasch2004/> The nebula is expanding with an average velocity of {{val|12.5|u=km/s}}. It consists of two shells: the inner shell is elliptical and measures {{nowrap|11″ × 6″}}, while the more rapidly expanding outer shell is rounder with a diameter of {{val|15|u=arcsecond}}. The inner shell has what appears to be multiple bubble-like shapes. The clumps in the outer shell may be the result of instabilities.<ref name=Corradi2000/>

The [[elemental abundance]]s of the nebula are very similar to those in the Sun, except for a times two enrichment of nitrogen. The latter suggests that the central star did not go through second [[dredge-up]]. The central star has an [[apparent visual magnitude]] of 13.43. It shines with 830 times the [[luminosity of the Sun]] and has 22.7% of the [[Sun's radius]].<ref name=Pottasch2004/> It is displaced slightly from the center of symmetry for the nebula.<ref name=Corradi2000/>
