142084 Jamesdaniel (2002 QU47) is a main-belt asteroid discovered on August 29, 2002 by James Whitney Young at the Table Mountain Observatory near Wrightwood, California.

Named for the combination of the two first names of James and Daniel, two sons of the discoverer’s friends Bob and Hazel Sealy of Seaside, Oregon. The Sealy family was partly instrumental in the discoverer’s early astronomical career. Bob Sealy founded the Seaside Amateur Astronomers Club and taught astronomy at Clatsop County College in Astoria, Oregon. James Sealy (1951–1978) was killed in a boating accident in 1978 on the ocean near Seaside, Oregon.
