623 Chimaera is a minor planet, specifically an asteroid orbiting in the asteroid belt.
Orbit and classification
[edit]The asteroid is the major body in the Chimaera Family. It is 22 kilometres in radius and orbits more in the inner to mid asteroid belt, taking 4 years to complete an orbit. Not much detail is known about the asteroid.
Exploration
[edit]The MBR Explorer spacecraft is going to visit 623 Chimaera among six other asteroids under the Emirates Mission to the Asteroid Belt. The spacecraft is planned to launch in 2028.[3][4] It will make observations of 623 Chimaera with its two cameras and two spectrometers with the goal of better understanding the formation of the Solar System.[5]
