Discovered by Andrew Graham on 25 April 1848, at Markree Observatory in Ireland. Metis (minor planet designation: 9 Metis) is one of the larger main-belt asteroids. It is composed of silicates and metallic nickel-iron, and may be the core remnant of a large asteroid that was destroyed by an ancient collision. Metis is estimated to contain just under half a percent of the total mass of the asteroid belt. - Dec 26 Full Moon - Dec 28 Asteroid 5 Astraea at Opposition! 5 Astraea is an asteroid in the asteroid belt. Its surface is highly reflective and its composition is probably a mixture of nickel-iron with silicates of magnesium and iron. It is an S-type asteroid in the Tholen classification system. Astraea was the fifth asteroid discovered, on 8 December 1845, by Karl Ludwig Hencke and named for Astraea, a Greek goddess of justice named after the stars. It was his first of two asteroid discoveries. The second was 6 Hebe. A German amateur astronomer and post office headmaster, Hencke was looking for 4 Vesta when he stumbled on Astraea. The King of Prussia awarded him an annual pension of 1,200 marks for the discovery. - Dec 30 Double Shadow Transit on Jupiter YES!   Concluding Listener Message: Just a reminder for our Patreon Calendar Draw, all you need to do is be a Patreon Supporter to be placed in our draw.
