Kiladze crater honors Rolan Kiladze (1931 – 2010), the Georgian (Caucasus) astronomer who made pioneering early investigations the dynamics, astrometry and photometry of Pluto.

Venera Terra is called for the Venera missions despatched to Venus by the Soviet Union from 1961 to 1984; they included the primary human-made gadget to enter the environment of one other planet, to make a delicate touchdown on one other planet and to return photographs from one other planetary floor.

The New Horizons spacecraft — constructed and operated on the Johns Hopkins Utilized Physics Laboratory in Laurel, Maryland, with a payload and science investigation led by Southwest Analysis Institute — is sort of four.1 billion miles (6.6 billion kilometers) from Earth. The spacecraft is in good well being and transmitting knowledge recorded from its New 12 months’s 2019 encounter with the Kuiper Belt object 2014 MU69, the farthest and most primitive object ever explored.
