- "Good evening, everyone! Tonight, we will discuss a fascinating exception to heliocentrism. Unlike the earth, rogue planets do not orbit a star, moving freely around space. The existence of rogue planets sheds new light on the intricate and unfamothable mechanisms of the galaxy. Locating rogue planets is a complicated process. Allow me to demonstrate."
- — Professor Sinistra regarding rogue planets[src]
A rogue planet was an interstellar object of planetary-mass, therefore smaller than fusors (stars and brown dwarfs) and without a host planetary system.[1] Rogue planets did not orbit stars and thus could move freely around space, and were difficult to locate. Billions of rogue planets existed in the Milky Way.[2]
History
The topic of rogue planets was taught during the 1990–1991 school year at Hogwarts School of Witchcraft and Wizardry to seventh-year Astronomy students by Professor Aurora Sinistra.[2]
