HD 80606
The yellow dwarf star HD 80606 is located 217 lightyears from the Solar system.[1][2] It is notable for being orbited by an exotic exoplanet, HD 80606 b, a planet four times the size of Planet Jupiter.
HD 80606 is part of a binary star system with HD 80607 -- another yellow dwarf star -- which orbit one another at an average distance of 1,200 astronomical units (0.019 ly).[1][2]

HD 80606 b is a very unique exoplanet with an insanely high orbital eccentricity. But as it turns out, there's an entire class of "eccentric Jupiter" planets like it. So, what's going on, how did these planets form, and what are their environments like?
