Ursa Minor train, of light" (i.e. λύκος "wolf" vs. λύκ- "light"). Allen points to the Old Irish name of the constellation, "drag-blod" "fire trail", for comparison. Brown (1899) suggested a non-Greek origin of the name (a loan from an Assyrian "An‑nas-sur‑ra" "high-rising"). An alternative myth tells of two bears that saved Zeus from his murderous father Cronus by hiding him on Mount Ida. Later Zeus set them in the sky, but their tails grew long from being swung up into the sky by the god. Because Ursa Minor consists of seven stars, the Latin word for "north" ("i.e.", where Polaris points) is
Ursa Major a binary system, orbits a common center of gravity with its partner, HD 80607; the two are separated by 1,200 AU on average. Research conducted in 2003 indicates that its sole planet, HD 80606 b is a future hot Jupiter, modeled to have evolved in a perpendicular orbit around 5 AU from its sun. The 4-Jupiter mass planet is projected to eventually move into a circular, more aligned orbit via the Kozai mechanism. However, it is currently on an incredibly eccentric orbit that ranges from approximately one astronomical unit at its apoapsis and six stellar radii at periapsis. Ursa Major
