High-Velocity Star [Astro*Index]A number of stars in the neighborhood of the Sun exhibit relative velocities which are extremely high, greater than 200 km/s. These apparently high velocities are due to the fact that most of the stars in the Sun's neighborhood, including the Sun itself, are moving around the center of our galaxy in approximately circular orbits with velocities of the order of 250 km/s. The high velocity stars do not share this common motion, and are being overtaken by stars such as the Sun.
