  Gliese 876 / Ross 780
Despite its close orbital distance, Gliese 876 is so dim that the presumed gaseous surface of the planet has a temperature around -75° C (-103° F) -- far below the freezing point of water -- according to calculations by Didier Saumon of Vanderbilt University.
The orbit of Gliese 876 c is also more elliptical (e= 0.26), even more than that of the planet Pluto in the Solar System.
Designated Gliese 876 "d", the object has a probable mass around 7.53 +/- 0.70 Earth-masses (0.024 Jupiter-masses) at an orbital inclination of 50° and a diameter less than twice (1.73) that of Earth's (NSF press release and images and videos).

 Astronomy Online - Gliese 876
Gliese 876 is a class M4 star with a visual magnitude of 10.1.
While the simulations of the Gliese 876 system are sensitive to the initial setup parameters of the Cartesian coordinates, this was not the case in simulating the above Solar System.
In the case of Gliese 876, the large bodies exhibit a 2/1 resonance – that is the middle planet – GJ876c - orbits at 30.3 days while the outer planet - GJ876b - rotates at 61 days.

 GJ 876 results
The depth duration and time of this event are consistent with an egress from transit of GJ 876 C. A co-planar, edge-on, three-body dynamical model for the GJ 876 system predicts a central transit epoch for C of 2003 Oct. 27.81 +/- 0.22d, and a central transit duration td=0.10d (assuming a primary radius r=0.3Rsun.
The air mass for GJ 876 ranged from sec z=2.7 to sec z=1.7, and observations were obtained in clear weather under twighlight conditions.
If the GJ 876 system is reasonably close to co-planar (as expected on the basis of planetary formation theory) then the transit probability of the inner planet is much higher than the geometric probability.
