6239 Minos (prov. designation: 1989 QF) is a bright sub-kilometer near-Earth object, classified as a potentially hazardous asteroid of the Apollo group. It was discovered on 31 August 1989, by American astronomer couple Carolyn and Eugene Shoemaker at the Palomar Observatory in California. The asteroid has a rotation period of 3.6 hours and measures approximately 0.5 kilometers (0.3 miles) in diameter. It makes frequent close approaches to Mars, Earth, and Venus.[1]
