4544 Xanthus,a near-Earth Apollo asteroid, was discovered Mar 31, 1989 by Henry E. Holt and Norman G. Thomas at Palomar Observatory near Pauma Valley, California. It has a period of 1 year, 23 days and has a diameter of just under a mile.
Xanthus (Greek for "fair" or "blond") is an epithet (nickname) of Apollo, a god fond of high places such as mountaintops. Xanthus can also mean "yellow."
Astrologically, asteroid Xanthus seems to indicate yellow and what is connoted or suggested by yellow, such as cowardice, caution, warning, golden, cheeriness, fun, sunshine.
The glyph for Xanthus is mine.
