Abell 48 is a planetary nebula likely located around 14,000 light years away[1] in the constellation of Aquila.
[5] The nebula is made up of two rings surrounding the central star, and is heavily reddened, with an E(B-V) value of 2.14 and a visual extinction of 6.634 magnitudes, which is why it appears so dim.
[3] The central star, with an initial mass of approximately 3 solar masses, would have left the asymptotic giant branch (AGB) approximately 9,000 years ago.
The central star of this nebula would be about 5,500 times brighter than the Sun, with a surface temperature of around 70,000 Kelvins and a size just under half that of the Sun.
[6] However, this may be slightly inaccurate given the different distance suggested by Gaia, which is about 67% larger than the one used in the study to derive the aforementioned properties.
