- Hans Hermann von Katte (28 February 1704 – 6 November 1730) was a Lieutenant of the Prussian Army, and a friend, tutor and possible lover of the future King Frederick II of Prussia, who was at the time the Crown Prince. Katte was executed by Frederick’s father, the Prussian King Frederick William I, when Frederick plotted to escape from Prussia to Britain. It was possible that Frederick intended to defect to the service of the British King George II (his maternal uncle) and possibly return to Prussia to depose his father.

486958 Arrokoth (provisional designation 2014 MU69; formerly nicknamed Ultima Thule) is a small, icy Kuiper belt object orbiting the Sun beyond Neptune and Pluto. It became the farthest object in the Solar System visited by a spacecraft when the NASA space probe New Horizons flew past it on 1 January 2019. Arrokoth was discovered on 26 June 2014 by astronomer Marc Buie and the New Horizons Search Team, who had been using the Hubble Space Telescope to find Kuiper belt objects that New Horizons could visit.
