4674 Pauling is an inner main belt asteroid. It is a member of the Hungaria family.[2] It was discovered by Eleanor F. Helin on 2 May 1989 from Palomar Observatory. Pauling measures about 8 km[2] in diameter. It is named after the scientist Linus Pauling.
In 2004, a team of astronomers at the European Southern Observatory announced that Pauling is orbited by a small moon. The moon has received the provisional designation S/2004 (4674) 1. It is believed to measure 2.5 km[2] in diameter and to orbit Pauling at a distance of 250 km. The primary period of the system is measured by its lightcurve to be 2.5306 ± 0.0003 hours.[2]
