Also known as NGC 3372, Caldwell 92, Eta Carinae Nebula.
One record per aspect. The origin says what kind of thing each value is; the source says where it came from; the limit says what it cannot tell you.
Carina Nebula is placed at J2000 RA 10.8 h, Dec -59.7° in Carina, at an adopted distance of 7,500 light-years.
Carina Nebula (star-forming emission nebula; central source Trumpler 16, massive young star cluster): measured footprint 230 × 160 light-years; display depth 34 light-years (not measured); outer radius used for arrival 115 light-years.
The physical footprint, cataloged clusters, Eta Carinae, Keyhole region, and NGC 3324 cavity are placed from observed sky structure at the common Carina distance. Their line-of-sight separations and the surrounding gas thickness are not directly measured; translucent gas is an extent-bounded reconstruction.
