YBP 1194 is a G-type main-sequence star, class G5V, in the open cluster Messier 67, about 2,890 light-years (890 parsecs) from the Sun in the constellation Cancer. It is a solar twin, having the near exact same temperature and mass as the Sun. YBP 1194 has a slightly higher metallicity than the Sun, and may be slightly younger at an age of 3.5-4.8 billion years. In January 2014, this star was announced to have an exoplanet.
This system is packed in a small cluster, Messier 67, with a radius of 10 light-years, with over 500 other stars. For comparison, the Sun has 9 star systems within 10 light-years and 94 star systems within 20 light-years.
