269 Justitia
Main-belt asteroid
269 Justitia is a fairly sizeable main belt asteroid around 50 km in diameter.
It was discovered by Johann Palisa on 21 September 1887 in Vienna.
The asteroid was named after Justitia, the Roman equivalent of Themis, the Greek goddess of justice (she also has an asteroid named after her, 24 Themis).
As discovered in 2021, the asteroid has a very red color due to tholins on its surface, similar to trans-Neptunian objects. It is therefore thought to have formed in the outer Solar System despite its current orbit within the asteroid belt.[3]
The asteroid will be visited by the United Arab Emirates' MBR Explorer mission, which will attempt to land on its surface in 2034.[4][5]
