Planets «b, c, and d» - On December 14, 2009, a team of astronomers (Steven S. Vogt; Robert A. Wittenmyer, R. Paul Butler, Simon O'Toole, Gregory W. Henry, Eugenio J. Rivera, Stefano Meschiari, Gregory Laughlin, C. G. Tinney, Hugh R. A. Jones, Jeremy Bailey, Brad D. Carter, and Konstantin Batygin) announced the discovery of one innermost orbiting super-Earth and two outer - orbiting, Neptune - class planets (with at least 5.1, 18.2, and 24.0 Earth - masses, respectively) in moderately circular, inner orbits around 61 Virginis with periods of 4.2, 38.0, and 124.0 days, based on radial - velocity observations over 4.6 years with the Keck Observatory's High Resolution Echelle Spectrometer (HIRES) and the Anglo - Australian Telescope (U.C. Santa Cruz news release; AAO press release; Keck press release; the Lick - Carnegie Exoplanet Survey Team's «Systemic Console;» and Vogt et al, 2009).
We present the discovery of Kepler - 421b, a Uranus - sized exoplanet transiting a G9 / K0 dwarf once every 704.2 days in a near - circular orbit.
Planet c may have a minimum mass around 54 + / - 0.7 percent of the mass of Jupiter with a semi-major axis of 3.6 + / -0.1 AUs and a roughly circular orbit (0.10 +0.5 / -0.1) that takes more than 6.5 years (2,391 +100 / -87 days) to complete (Gregory and Fischer, 2010; and Fischer et al, 2001 — in pdf).
It moves around Star A at an average distance of less than 0.05 AUs (a semi-major axis well within Mercury's orbital distance) in a near circular orbit (e = 0.23 + / - 0.015) that takes 3.312 days to complete.

The Trace Gas Orbiter has reached its final orbit after a year of «aerobraking» that ended in February.This exciting operation saw the craft skimming through the very top of the upper atmosphere, using drag on its solar wings to transform its initial highly elliptical four - day orbit of about 200 x 98 000 km into the final, much lower and near - circular path at about 400 km.

It revolves around GJ 1214 at an average distance of 0.014 AU, in a roughly circular orbit (e < 0.27) which it completes in 1.6 days (38 hours), and so the planet must have a very hot equilibrium temperature — updated in 2011 to around 555 kelvin, 539 ° Fahrenheit, or 282 ° Celsius (Desert et al, 2011, page 6).
