Shapley 1 (Sp 1 or PLN 329+2.1)[3] is an annular planetary nebula in the constellation of Norma with a magnitude of +12.6.

[4] As viewed from Earth, it is peculiar in that it seems to be a non-bipolar, torus-shaped planetary nebula.

However, it is thought that this is due to the viewpoint of looking directly down on a binary system whose orbit is perpendicular to Earth.

[2] At the center of the nebula is a magnitude 14 white dwarf star.

It has an angular diameter of 1.1 arc minutes,[5] which makes it about one-third (.32) of a light year across.
