3362 Khufu is a
numbered
.
3362 Khufu is a
potentially hazardous asteroid (PHA) because its minimum 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 of Mars, Earth, and Venus and makes close approaches to Mercury 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.
