Planetary Nebula Kohoutek 3-46
History
The planetary nebula Kohoutek 3-46 (K 3-46, PK 69+3.1) was discovered in 1972 by the Czechoslovak astronomer Luboš Kohoutek during his Hα Schmidt-Camera survey for faint planetary nebulae at Hamburg Observatory. [748]
Physical Properties
The PN has a well-defined hourglass shape with a prominent equatorial ring and marked waist. The expansion rate is very slow. In the equatorial plane it is less than 3 km/s and in the polar direction about 18 km/s. The age is estimated to be around 20'000 years and the distance to be 2.2 kpc (around 7200 light years). [338]
