Hi Nick
Just been checking myself and I think it’s an asteroid –
(787) Moskva is a 13th magnitude Asteroid appearing in the constellation Monoceros. It orbits the sun every 4.0 years at an average distance of 2.5 AU. It is a main belt asteroid which orbits the Sun between Mars and Jupiter.
(787) Moskva, a small asteroid, is roughly 27 kilometers across.
