Eta Coronae Borealis

Index Eta Coronae Borealis

Eta Coronae Borealis (η Coronae Borealis, η CrB) is a stellar system that lies approximately 58 light-years away. [1]

6 relations: Brown dwarf, Circumstellar habitable zone, Corona Borealis, Light-year, 2MASS, 81 Cancri.

Brown dwarf

Brown dwarfs are substellar objects that occupy the mass range between the heaviest gas giant planets and the lightest stars, having masses between approximately 13 to 75–80 times that of Jupiter, or approximately to about.

Circumstellar habitable zone

In astronomy and astrobiology, the circumstellar habitable zone (CHZ), or simply the habitable zone, is the range of orbits around a star within which a planetary surface can support liquid water given sufficient atmospheric pressure.
