The planet orbits the K-type star Kepler-1544, which has a metallicity of 0.02 Fe/H.[citation needed]
Kepler-1544b is considered a super-Earth with a radius of 1.78 Earth radii and an estimated mass of 3.82 Earth masses.[2]
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).[3]
Despite the fact that NASA considers this planet gaseous, it could have a surface composition considering that its mass stays below 10 Earth masses.[4]
