Asteroid 21409, Forbes, was discovered on March 20, 1998 by MIT Lincoln Laboratory's Near-Earth Asteroid Research (LINEAR) program. It has a period of 3 years, 158 days.
It was named for Silver Spring, Maryland high-school student Michael Andrew Forbes (born 1987), who entered a computer-science project in the 2005 Intel Science Talent Search, reaching the finals.
The astrological meaning of asteroid Forbes, however seems to be informed by the famous family of publishers and business people: finance, wealth, "fat cats," rules or obligations applying to all.
The glyph for Forbes is mine.
