... Brown dwarfs are substellar objects with insufficient mass to sustain nuclear fusion in their cores. They have higher surface temperatures than planets and masses between 10to 80 times that of Jupiter. Brown dwarfs have no habitable zones because they are so dim. However, recent infrared observation ...

... The solution to the planetary tempearture comes from assuming a state of “balanced power”. The energy received per second by the planet from its host star, Ėin is balanced by the energy it radiates per second as a blackbody, Ėout . If this were not so, then the temperature of the planet would rise ...

Ursa Major
Ursa Major /ˈɜrsə ˈmeɪdʒər/ (also known as the Great Bear and Charles' Wain) is a constellation in the northern celestial hemisphere. One of the 48 constellations listed by Ptolemy (second century AD), it remains one of the 88 modern constellations. It can be visible throughout the year in most of the northern hemisphere. Its name, Latin for ""the greater (or larger) she-bear"", stands as a reference to and in direct contrast with Ursa Minor, ""the smaller she-bear"", with which it is frequently associated in mythology and amateur astronomy. The constellation's most recognizable asterism, a group of seven relatively bright stars commonly known as the ""Big Dipper"", ""the Wagon"" or ""the Plough"" (among others), both mimicks the shape of the lesser bear (the ""Little Dipper"") and is commonly used as a navigational pointer towards the current northern pole star, Polaris in Ursa Minor. The Big Dipper and the constellation as a whole have mythological significance in numerous world cultures, usually as a symbol of the north.The third largest constellation in the sky, Ursa Major is home to many deep-sky objects including seven Messier objects, four other NGC objects and I Zwicky 18, the youngest known galaxy in the visible universe.
