Planetary Nebula Abell 5
The planetary nebula Abell 5 (PK 141-7.1) was discovered in 1955 by the American astronomer George Ogden Abell on the photo plates of the «Palomar Observatory Sky Survey» (POSS). Most of these 86 PNs discovered on the POSS photo plates are large and have a low surface brightness, which suggests that their stage of development is advanced. Abell described the PN as an incomplete ring with a diameter of 134" x 121". [331, 332]
Abell 5 is an old and faint planetary nebula at a distance of 1658 pc.
