Problem 15SEQ
Explain answer clearly, with complete sentences and proper essay structure if needed.
High-Velocity Star. The average speed of stars in the solar neighborhood relative to the Sun is about 20 km/s (i.e., the speed at which we see stars moving toward or away from the Sun—not their orbital speed around the galaxy). Suppose you discover a star in the solar neighborhood that is moving relative to the Sun at a much higher speed—say, 200 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.

ANSWER:
Solution 15SEQ:
Step 1 of 2:-
Here we have to explain, what kind of orbit will be there for a star which is moving at a speed of w.r.t sun.
We know that, the average speed of the stars in the solar neighbourhood is .
Most of the stars of our galaxy which are present in the disc of milky way, move at an average speed of .
But the disc does not represent the whole milky way. There are other stars which move differently and they are called halo stars.
Their orbit is distributed on a spherical shell as they keep changing their paths on the shell.
