Kepler-1544b is a potentially habitable (optimistic sample) exoplanet announced in 2016 and located 1138 light years away, in the constellation of Cygnus.
Characteristics
The planet orbits the K-type star Kepler-1544, which has a metallicity () of −0.08 and an effective temperature of 4,820 K.
Kepler-1544b is considered a super-Earth with a radius of 1.71 Earth radii.
Habitability
With an orbital period of 168 days, the exoplanet is located at 0.54 AU from the star, which is close to the orbital distance at Earth's Equivalent Radiation (0.49 AU).
Despite the fact that NASA considers this planet gaseous, it could have a surface composition considering that its mass stays below 10 Earth masses.
