NGC 3195 is a planetary nebulae located in the constellation Chamaeleon. It is the most southern of all the bright planetary nebula in the sky, and remains completely invisible to all northern observers. It was first discovered by Sir John Herschel in 1835, and can be visually seen in telescopic apertures of 10.5cm (4-inches) at low magnifications, where it appears as a slightly oval in shape, being some 40×35 arcsec in size. NGC 3195 shares the place as one of the favourite planetary nebulae in the far southern skies, probably being just after the brighter Centaurus planetary, NGC 3918.
Spectroscopy reveals NGC 3195 is approaching us at 17 kilometres per second, while the nebulosity is expanding at around 40 kilometres per second. The central star is listed as >15.3V or 16.1B magnitude, and remains invisible to visual observers.
Distance is presently estimated at about 1.7 kpc.
