Oph 11 and Its Imaged Companion
Oph 11 is an M9 host star, placing it among the small, cool red dwarfs. Its spectral class is cooler than the Sun's, and its reported temperature is 2380 K. The star's reported mass estimate is 0.016 solar masses, smaller than the Sun's, and its age is 5 billion years. One planet orbits this host.
That planet is Oph 11 b, discovered by imaging in 2006. It has a reported mass estimate of 4450 Earth masses, larger than Earth's and roughly 14 times Jupiter's mass. Its orbital period is 7300000 days.
