===Extrasolar planets===
[[HD 80606]], a sun-like star in a binary system, orbits a common center of gravity with its partner, [[HD 80607]]; the two are separated by 1,200&nbsp;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&nbsp;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 [[orbital eccentricity|eccentric orbit]] that ranges from approximately one astronomical unit at its [[apoapsis]] and six stellar radii at [[periapsis]].<ref>{{cite journal |title = How Worlds Get Out of Whack |first = Greg |last = Laughlin |journal = Sky and Telescope |date = May 2013 |volume = 125 |issue = 5 |page = 29|bibcode = 2013S&T...125e..26L }}</ref>
