A near-Earth binary asteroid system, named after the Greek word for ‘twin’, Didymos’s main body measures about 780 m across, with its previously nameless moonlet about 160 m in diameter, approximately the size of Egypt’s Great Pyramid.

The current Right Ascension of Asteroid 65803 Didymos (1996 GT) is 02h 05m 22s and the Declination is +07° 12’ 14” (topocentric coordinates computed for the selected location: Greenwich, United Kingdom [ change ]). The sky map shown below represents a rectangular portion of the sky 60x40 arcminutes wide. This page shows Asteroid 65803 Didymos (1996 GT)location and other relevant astronomical data in real time. Asteroid 65803 Didymos (1996 GT) is currently in the constellation of Pisces. NASA’s DART impacting asteroid Due to its binary nature, it was then named "Didymos", the Greek word for twin. This video is sponsored my Magellan TV. Asteroid 65803 Didymos is a binary near-Earth asteroid; the main body has a size of around 780 m and a rotation duration of 2.26 hours, whereas the Didymoon secondary body has a size of around 160 m and turns around the main at a range of around 1.2 km from the main surface area in […] 65803 Didymos, provisional designation 1996 GT, is a sub-kilometer asteroid and synchronous binary system, classified as potentially hazardous asteroid and near-Earth object of both the Apollo and Amor group. The binary near-Earth asteroid (65803) Didymos is the target for DART.

This is AIDA, the Asteroid Impact and Deflection Assessment mission that will test out the theories on the double asteroid Didymos. 65803 Didymos (Greek for "twin") is a binary, S-type near-Earth asteroid system. The system was discovered in 1996 by Spacewatch at Kitt Peak, Arizona, and confirmed as a binary asteroid in 2003. Didymos is a sub-kilometer asteroid and synchronous binary system, classified as potentially hazardous asteroid and near-Earth object.

The asteroid was discovered in 1996, by the Spacewatch survey at Kitt Peak, and its small 160-metre minor-planet moon was discovered in 2003, named Dimorphos. Depending on the device you are using, the map can be dragged horizondally or vertically using the mouse or touchscreen. While Didymos’ primary body is approximately 800 meters across, its secondary body (or “moonlet”) has a diameter of about 150 m, which is more typical of the size of asteroids that could pose a more common hazard to Earth. Asteroid Targeted by Planetary Defence Missions is Named In 2022 NASA will atempt an ambitious mission to deflect a small asteroid.
