Description

Abell 13 is highly evolved planetary nebula in Orion. It is sometimes known as the Orion Ring Nebula because it's morphology resembles the better known Ring Nebula, M57. However Abell 13 is much fainter at around mag 16. In both cases their oval shape is believed to be a result of them being bipolar nebulae viewed offset from their axis, making their ring structure appear oval. Abell 13 is 2.9 arc minutes in angular size and around 3,500 light years away. It was first catalogued as Abell 9 by George Abell in 1955, but renumbered as Abell 13 in his 1966 paper.
