Space Time
Also known as HD 44179, Red Rectangle 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.
Red Rectangle image-field center is placed at J2000 RA 6.3 h, Dec -10.6° in Monoceros, at an adopted distance of 2,300 light-years.
Red Rectangle (preplanetary nebula; central source Red Rectangle, illuminating stellar system): projected footprint at the adopted distance 0.3 × 0.3 light-years; outer radius used for arrival 0.2 light-years.
A small archival Hubble field with finite resolution. The displayed shape is projected dust-scattered light, not a solid rectangle. Projected structure follows the credited observation at its published angular scale and an approximate adopted distance. Shallow depth is illustrative, not measured tomography. The source palette is preserved; brightness is adjusted for the navigable view.
