On what planet was a large rectangular outcrop that is composed mainly of sandstone first observed by an English astronomer born 1618?
Jeremiah Horrocks Jeremiah Horrocks (1618 – 3 January 1641), sometimes given as Jeremiah Horrox (the Latinised version that he used on the Emmanuel College register and in his Latin manuscripts), was an English astronomer. He was the first person to demonstrate that the Moon moved around the Earth in an elliptical orbit; and he was the only person to predict the transit of Venus of 1639, an event which he and his friend William Crabtree were the only two people to observe and record.
Kepler-1229b Kepler-1229b (also known by its Kepler Object of Interest designation "KOI-2418.01") is a confirmed super-Earth exoplanet, likely rocky, orbiting within the habitable zone of the red dwarf star Kepler-1229, located about 770 light years (236 parsecs, or nearly km) from Earth in the constellation of Cygnus. It was discovered in 2016 by the "Kepler" space telescope. The exoplanet was found by using the transit method, in which the dimming effect that a planet causes as it crosses in front of its star is measured.
