NGC 3195 (also known as Caldwell 109) is a planetary nebula located in the southern constellation of Chamaeleon. Discovered by Sir John Herschel in 1835, this 11.6 apparent magnitude planetary nebula is slightly oval in shape, with dimensions of 40×35 arc seconds, and can be seen visually in telescopic apertures of at low magnifications.
Spectroscopy reveals that NGC 3195 is approaching Earth at, while the nebulosity is expanding at around . The central star is listed as >15.3V or 16.1B magnitude. An analysis of Gaia data suggests that the central star is a binary system.[1] Distance is estimated at 1.7 kpc.
