Asteroid 18555, Courant, was discovered February 4, 1997 by Paul G. Comba at Prescott, Arizona. Courant has a period of 4 years, 283 days.
It was named for Polish-born German-American mathematician Richard Courant (1888-1972), who in 1934 became a professor at New York University, where he founded the prestigious Courant Institute of Mathematics.

The astrological meaning of asteroid Courant seems to be what its name might suggest: recent, current, up-to-date, getting up to speed.
The glyph for Courant is mine.
