The average speed of stars relative to the Sun in the solar neighborhood is about 20 km/s. Suppose you discover a star in the solar neighborhood that is moving relative to the Sun at a much higher speed, say 220 km/s

What kind of orbit does this star probably have around the Milky Way? In what part of the galaxy does it spend most of its time? Explain.
