Characteristics
Visually it has an apparent magnitude of 10.6 and an apparent size of 12 arcseconds and like other objects of its class a nebular filter may help on its observation.[3]
Its distance to the Solar System has been estimated to be around 1.1 kiloparsecs, having a total mass of 0.03 solar masses and being thought to have been produced by a low-mass star.[4]
Some authors have proposed the planetary nebula that the Sun will produce will be similar to this one, but smaller.[5]
The central star of the planetary nebula is an O-type star with a spectral type of O(H)4f.[6]
