Potentially Hazardous Asteroid
1566 Icarus (1949 MA) 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.
Asteroid
1566 Icarus is a large near-Earth object of the Apollo group and the lowest numbered potentially hazardous asteroid. It has an extremely eccentric orbit (0.83) and measures approximately 1.4ย km (0.87ย mi) in diameter. In 1968, it became the first asteroid ever observed by radar. Its orbit brings it closer to the Sun than Mercury and further out than the orbit of Mars, which also makes it a Mercury-, Venus-, and Mars-crossing asteroid. This stony asteroid and relatively fast rotator with a period of 2.27 hours was discovered on 27 June 1949, by German astronomer Walter Baade at the Palomar Observatory in California. It was named after the mythological Icarus.
Frequently Asked Questions
Is 1566 Icarus (1949 MA) dangerous?โพ
1566 Icarus (1949 MA) 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.
How close will 1566 Icarus (1949 MA) come to Earth?โพ
The closest recorded Earth approach of 1566 Icarus (1949 MA) is 0.0845 AU (12.6 million km) on June 11, 1902, at a speed of approximately 27.0 km/s.
How big is 1566 Icarus (1949 MA)?โพ
1566 Icarus (1949 MA) has an estimated diameter of 2.13 km (1314โ2938 meters range). Its absolute magnitude (H) is 16.53, which NASA uses along with assumed albedo to estimate size.
