Images of NGC 3132 reveal two stars close together within the nebulosity, one of 10th [[Apparent magnitude|magnitude]], the other 16th, located about 1.7{{pprime}} away from the central star. The central star of the planetary nebula is a [[white dwarf]], and is the fainter of the two stars. This hot central star of about 100,000 [[kelvin|K]] has now blown off its outer layers and is making the nebula fluoresce brightly from the emission of its intense [[ultraviolet]] [[radiation]].<ref>{{cite journal |bibcode=2020A&A...634A..47M |title=The MUSE view of the planetary nebula NGC 3132 |last1=Monreal-Ibero |first1=Ana |last2=Walsh |first2=Jeremy R. |journal=Astronomy and Astrophysics |year=2020 |volume=634 |pages=A47 |doi=10.1051/0004-6361/201936845 |arxiv=1912.02847 |s2cid=208857629 }}</ref> The 10th magnitude star is an [[A-type main-sequence star]] of type A2V, and is separated from the white dwarf by at least 1277 [[astronomical unit|au]].<ref name=Sahai>{{cite journal|doi=10.3847/1538-4357/aca7ba|title=The Binary and the Disk: The Beauty is Found within NGC3132 with JWST |year=2023 |last1=Sahai |first1=Raghvendra |last2=Bujarrabal |first2=Valentin |last3=Quintana-Lacaci |first3=Guillermo |last4=Reindl |first4=Nicole |last5=Van De Steene |first5=Griet |last6=Contreras |first6=Carmen Sánchez |last7=Ressler |first7=Michael E. |journal=The Astrophysical Journal |volume=943 |issue=2 |page=110 |arxiv=2211.16741 |bibcode=2023ApJ...943..110S |s2cid=254096318 |doi-access=free }}</ref> The A-type star orbits at roughly the same distance as the edge of a dust cloud surrounding the central white dwarf.<ref name=Sahai/> The system is likely a quadruple [[star system]].<ref name=DeMarco/>
