 It could belong to a class of planets that are thought to contain up to 40% water (in the form of ice and/or vapor) in addition to rock.However, the fact that it formed so close to its parent star may mean that it is depleted of volatiles.A strong possibility exists that the planet's rotation is tidally locked to the orbital period, so that temperatures and geologic conditions on the sides of the planet facing towards and away from the star may be dramatically different.
