6239 Minos (1989 QF) is classified as a Potentially Hazardous Asteroid (PHA) because it is estimated to be larger than 140 meters and its orbit comes within 0.05 AU of Earth. NASA continuously monitors this object for any future impact risk. Current data does not indicate a confirmed impact event.
Bright sub-kilometer near-Earth object
6239 Minos 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 in diameter. It makes frequent close approaches to Mars, Earth, and Venus.
6239 Minos (1989 QF) is classified as a potentially hazardous asteroid (PHA) by NASA. This means it is large enough and its orbit brings it close enough to Earth to warrant close monitoring. However, a PHA classification does not mean an impact is imminent.
The closest recorded Earth approach of 6239 Minos (1989 QF) is 0.1954 AU (29.2 million km) on August 23, 1900, at a speed of approximately 18.6 km/s.
6239 Minos (1989 QF) has an estimated diameter of 0.823 km (509โ1138 meters range). Its absolute magnitude (H) is 18.59, which NASA uses along with assumed albedo to estimate size.
