HD 181433 c
HD 181433 c is an extrasolar planet located approximately 87 light years away in the constellation of Pavo, orbiting the star HD 181433. This planet has mass at least 0.64 times that of Jupiter and takes 962 days to orbit the star at an orbital distance of 1.76 AU or 263 Gm. However, the orbit is eccentric, which ranges from 1.27 AU (190 Gm) at periastron to 2.25 AU (337 Gm) at apastron. François Bouchy "et al." have published a paper detailing the
termed a “hot Neptune”. The outer planet HD 47186 c orbits in a similar distance from the star as the asteroid Vesta, at around 2.4 AU. The inner planet orbits in a circular path while the outer planet orbits in an eccentric path.
