4034 (1986 PA) is an Apollo asteroid, 0.8 kilometers in diameter. It completes one revolution around the Sun almost once every year. It was disclovered by Eleanor F. Helin at the Palomar Observatory in San Diego County, California on August 2, 1986. It is an O-type asteroid, meaning it is similar to the asteroid 3628 Boznemcová, which is the best asteroid match to the spectra of L6 and LL6 ordinary chondrite meteorites. L and LL chondrites have lower iron and metal content, but higher iron oxide content in the silicates.[1][2]
