2675 Tolkien, provisional designation 1982 GB, is a stony Florian asteroid and extremely slow rotator from the inner regions of the asteroid belt, approximately 10 kilometres (6.2 mi) in diameter. It was discovered on 14 April 1982, by British astronomer Martin Watt at Lowell's Anderson Mesa Station in Flagstaff, Arizona, and later named for J. R. R. Tolkien.[2][8]
