HD 107146 is a star in the constellation Coma Berenices that is located about 90 light-years (28 pc) from Earth. The apparent magnitude of 7.028 makes this star too faint to be seen with the unaided eye.
The physical properties of this star are similar to the Sun, including the stellar classification G2V, making this a solar analog. The mass of this star is about 109% of the solar mass (M☉) and it has about 99% the radius of the Sun (R☉). It is a young star with an age between 80 and 200 Myr. The axis of rotation is estimated at 21+8
−9 degrees to the line of sight and it completes a rotation in a relatively brief 3.5 days.
