HD 187123 c [SEP] constellation
HD 187123 c
HD 187123 c is an extrasolar planet located approximately 156 light-years away in the constellation of Cygnus, orbiting the star HD 187123. This planet was published in 2006. The radius of the planet's orbit is 4.80 AU, 113 times more distant from the star than first companion. This takes 10 years to orbit. As it is typical for very long-period planets, the orbit is eccentric, referring to as "eccentric Jupiter". At periastron, the orbital distance is 3.60 AU and
at apastron, the distance is 6.00 AU. The planet's mass is nearly 2 times that of Jupiter, but is likely to be smaller in size than the inner planet.
