Dr 36, PN-G 125.3-08.9

Year of discovery: 2019

planetarynebulae.net/FR/page_np.php?id=681

Coordinates: 01:07:40.04 +53:52:24.02

Constellation Cassiopeia

Diameter: 2.7 x 2.1 arc minutes

Type: faint, bubble-like planetary nebula with surrounding ISM and central white dwarf (CSPN), high proportions of HII, low proportions of OIII

 

CSNP:

Distance (average) 3653 light-years

proper motion of the star: pmra: 2,466 / pmdec -8,912 mas/yr

The high proper motion of the star explains that the CSNP is not in the center of the object.
