HD 107146 is a star in the constellation Coma Berenices that is located about 90 light-years (28 pc) from Earth.
The physical properties of this star are similar to the Sun, including the stellar classification G2V,[4] making this a solar analog.
[7] In 2003, astronomers recognized the excess infrared[12] and submillimeter[10] emission indicative of circumstellar dust, the first time such a debris disk phenomenon was noted around a star of similar spectral types to the Sun, though having a much younger age.
In 2004 the Hubble Space Telescope detected the presence of a spatially resolved disk surrounding the star.
[8] The disk appears to be slightly elongated to form an ellipse with its minor axis at a position angle of 58° ± 5°; working under the assumption that the disk is in fact circular gives it an inclination of 25° ± 5° from the plane of the sky.
