Definición
- A planetary nebula is a luminous shell of gas, often of complex structure, cast off and caused to fluoresce by an evolved star of less than about 4 solar masses. Planetary nebulae have nothing to do with planets other than their name, which was coined by William Herschel, in the 1780s, because their appearance suggested to him the greenish disk of Uranus. (Encyclopedia of Science, by David Darling, https://www.daviddarling.info/encyclopedia/P/planneb.html)
