NGC 2792

[1] NGC 2792 was discovered by British astronomer John Herschel in 1835.

[2] With an apparent visual magnitude of 11.6,[3] you must use a telescope with an aperture of at least 200 mm to observe it.

[5] The kinematic age of a planetary nebula can be estimated from its expansion speed.

According to González-Santamaría and his colleagues, the expansion speed of NGC 2792 is 20 km/s, which gives it a kinematic age of 3.5 thousand years.

[6] According to González-Santamaría, it has been approximately 50,860 years since the star left the asymptotic giant branch and the nebula enveloping it reached 1% of the mass of the progenitor.
