Kepler-1544b is a potentially habitable (optimistic sample) exoplanet announced in 2016 and located 1138 light years away, in the constellation of Cygnus.[2]

Characteristics

The planet orbits the K-type star Kepler-1544, which has a metallicity ([FE/H]) of −0.08 and an effective temperature of 4,820 K.[3]

Kepler-1544b is considered a super-Earth with a radius of 1.71 Earth radii.[4]

Habitability

With an orbital period of 168 days,[4] 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).[5]

Despite the fact that NASA considers this planet gaseous, it could have a surface composition considering that its mass stays below 10 Earth masses.[6]
