It was not at first designated as a Kepler object of interest, as data analysis failed to identify it due to its short orbital period.

While the method has been used to characterize gas giants, it is difficult to estimate the mass of Earth-sized exoplanets, because their gravity is too weak to produce a visible influence.

[9] One team, led by Francesco Pepe, used the High Accuracy Radial Velocity Planet Searcher-North (HARPS-N) spectrograph at the Telescopio Nazionale Galileo in the Canary Islands[10] to estimate that the planet has a mass 1.86 times that of the Earth and a radius 1.16 times greater.

The other, led by Andrew Howard of the University of Hawaii at Manoa, used data from the High Resolution Eschelle Spectrometer at the W.M.

[12] Due to its extremely close solar orbit, which is about 40 times closer than Mercury is to the Sun, the planet's surface is estimated to be at a temperature of 2,200 K (1,930 °C; 3,500 °F).

But one thing that is certain, it can't stay roasting in that hellish orbit for long; it's destined to get swallowed by its star very soon".
