Asteroid 2884, Reddish, was discovered on March 2, 1981 by SJ (Buddy) Bus at Siding Spring Observatory near Coonabarabran, New South Wales, Australia. It has a period of 5 years, 175 days.
It was named for Vincent C. Reddish (born 1926), Royal Astronomer for Scotland from 1975 to 1980 and a director of the Royal Observatory at Edinburgh. He helped organize a survey of the southern sky at Siding Spring.
The meaning of asteroid Reddish seems to be what its name might suggest: something to blush about, embarrassment, anger, rashes, disorders and diseases that cause rashes, things that are reddish, possibly radishes.
