Binary asteroid 90 Antiope
Référence de la vidéo 11927980
| Binary asteroid 90 Antiope. 90 Antiope was found to be a double asteroid in 2000, over 130 years after it was discovered. Unusually, both components are similar in size, and they orbit their common centre of mass, which lies between them. The asteroids are both around 86 kilometres in diameter, with their centres separated by 171 kilometres, meaning their surfaces are about as close to each other as they are wide. They orbit one another every 16.5 hours. They are thought to be loose aggregations of rubble rather than solid rock, as their density is very low, only 25% higher than that of water. The 90 Antiope system orbits the Sun in the Themis family of the Asteroid Belt between Mars and Jupiter, taking 5.6 years to complete one orbit. | |
