The discovery of a new triple asteroid – (93) Minerva


So I was quite mysterious after my observations at Keck Observatory, and I briefly mentioned that we discovered something interesting during the night. I will give a little bit more details in this blog since the IAU circular announcing the result is about to be published. To summarize, the high angular resolution images provided by the Keck Adaptive Optics system revealed that the asteroid 93 Minerva possesses 2 tiny km-sized moons in orbit around the large 140-km primary.
