Kepler-61 is a K7 V star 1090 light-years away. A spectral type like K7 V places it among the cooler, redder stars than the Sun, and as a main-sequence dwarf. Its reported mass is 0.635 solar masses and its reported radius 0.62 solar radii, both smaller than the Sun's. Its reported temperature is 4020 K, cooler than the Sun's, and its age is given as a reported lower limit of 1 billion years.
One planet is known to orbit this star. Kepler-61 b was discovered in 2013 by the transit method, in which a planet passing in front of its star from our viewpoint causes a small dip in observed brightness; repeated dips help establish orbital periods. Kepler-61 b is classified as a Super-Earth, a size class reaching 2.5 times Earth's radius, and its reported radius is 2.15 Earth radii, larger than Earth's. It completes an orbit in 59.9 days.
