HD 107146
HD 107146 is a G2V (yellow dwarf) star, located 88 lightyears from Earth. In 2004, astronomers using the Hubble Space Telescope detected the presence of a disc of dust surrounding the star, the first time such a phenomenon has been detected around a star of similar spectral type and age as the Sun, which also had a detectable planetary system. Observations have given the age of the star at between 80 and 200 Myr.
