High-velocity Stars
Depending on the definition, a high-velocity star is a star moving faster than 65 km/s to 100 km/s relative to the average motion of the stars in the Sun's neighbourhood. The velocity is also sometimes defined as supersonic relative to the surrounding interstellar medium. The three types of high-velocity stars are: runaway stars, halo stars and hypervelocity stars.

Famous quotes containing the word stars:
“And now the sparrows warring in the eaves,
The curd-pale moon, the white stars in the sky,
And the loud chaunting of the unquiet leaves,
Are shaken with earth’s old and weary cry.”
—William Butler Yeats (1865–1939)
