3362 Khufu is anear-Earthasteroid. It was discovered byR. Scott Dunbar andMaria A. Barucci at thePalomar Observatory inSan Diego County, California, on 30 August 1984. Its provisional designation was1984 QA. It is named afterKhufu, anancient Egyptian pharaoh. Khufu was the 4thAten asteroid to benumbered.
3362 Khufu is apotentially hazardous asteroid (PHA) because itsminimum orbit intersection distance (MOID) is less than 0.05 AU and its diameter is greater than 150 meters. The Earth-MOID is 0.0135 AU (2,020,000 km; 1,250,000 mi).[2] Its orbit is well-determined for the next several hundred years.
Khufu crosses the orbits ofMars,Earth, andVenus and makes close approaches toMercury as well. From 1900 to 2100 it drew nearer than 30 Gm (0.2 AU) to Mercury 26, Venus 27, Earth 20, and Mars 11 times.
