Question: On what planet was a large rectangular outcrop that is composed mainly of sandstone first observed by an English astronomer born 1618?

full_context: Document 1: Heavens-Above: Heavens-Above is a non-profit website developed and maintained by Chris Peat as "Heavens-Above GmbH". The web site is dedicated to helping people observe and track satellites orbiting the Earth without the need for optical equipment such as binoculars or telescopes. It provides detailed star charts showing the trajectory of the satellites against the background of the stars as seen during a pass. Special attention is paid to the ISS, Iridium flares and other satellites. Space shuttle missions were tracked until the program was retired in July 2011. The website also offers information on currently visible comets, asteroids, planet details, and other miscellaneous information.
Document 2: The Man in the Moone: The Man in the Moone is a book by the English divine and Church of England bishop Francis Godwin (1562–1633), describing a "voyage of utopian discovery". Long considered to be one of his early works, it is now generally thought to have been written in the late 1620s. It was first published posthumously in 1638 under the pseudonym of Domingo Gonsales. The work is notable for its role in what was called the "new astronomy", the branch of astronomy influenced especially by Nicolaus Copernicus. Although Copernicus is the only astronomer mentioned by name, the book also draws on the theories of Johannes Kepler and William Gilbert. Godwin's astronomical theories were greatly influenced by Galileo Galilei's "Sidereus Nuncius" (1610), but unlike Galileo, Godwin proposes that the dark spots on the Moon are seas, one of many parallels with Kepler's "Somnium sive opus posthumum de astronomia lunari" of 1634.
Document 3: Horrocks Block: Horrocks Block ( ) is a large rectangular outcrop that is composed mainly of sandstone, lying on the north side of Venus Glacier, 2 nmi southwest of the Keystone Cliffs, on the east side of Alexander Island, Antarctica. It was mapped by the Directorate of Overseas Surveys from satellite imagery supplied by the U.S. National Aeronautics and Space Administration in cooperation with the U.S. Geological Survey, and was named by the UK Antarctic Place-Names Committee from association with Venus Glacier after Jeremiah Horrocks, the British astronomer who predicted and first observed a transit of Venus, in 1639.
Document 4: Victoria (crater): Victoria is an impact crater on Mars located at 2.05°S, 5.50°W in the Meridiani Planum extraterrestrial plain, lying situated within the Margaritifer Sinus quadrangle (MC-19) region of the planet Mars. This crater was first visited by the Mars Exploration Rover "Opportunity". It is roughly 730 metres wide, nearly eight times the size of the crater Endurance, visited by "Opportunity" from sols 951 to 1630. It is informally named after "Victoria" – one of the five ships of Ferdinand Magellan and the first ship to circumnavigate the globe – and formally named after Victoria, Seychelles. Along the edges of the crater are many outcrops within recessed alcoves and promontories, named for bays and capes that Magellan discovered.
Document 5: Johannes de Sacrobosco: Johannes de Sacrobosco, also written Ioannis de Sacro Bosco ( 1195 – 1256), was a scholar, monk and astronomer who was a teacher at the University of Paris. He wrote a short introduction to the Hindu–Arabic numeral system which became the most widely read introduction to that subject in the later medieval centuries (judging from the number of manuscript copies that survive today). He also wrote a short astronomy textbook, "Tractatus de Sphaera", which was widely read and influential in Europe during the later medieval centuries as an introduction to astronomy. In his longest and most original book, Sacrobosco correctly described the defects of the then-used Julian calendar, and, three centuries before its implementation, recommended a solution much like the modern Gregorian calendar.
Document 6: Newbrook Observatory: The Newbrook Observatory (a designated historic building) was built in Newbrook, Alberta, Canada by the Stellar Physics Division of the Dominion Observatory and operated as a space observatory from 1952 until 1957 The observatory was equipped with a Super-Schmidt Meteor Camera, one of only six built by the Perkin-Elmer Company used to observe meteors. One of the observatory resident scientists, Art Griffen, was the first in North America to photograph the Sputnik 1 satellite (less than a week after its launch).
Document 7: Astronomia nova: Astronomia nova (English: "New Astronomy", full title in original Latin: ) is a book, published in 1609, that contains the results of the astronomer Johannes Kepler's ten-year-long investigation of the motion of Mars. One of the most significant books in the history of astronomy, the "Astronomia nova" provided strong arguments for heliocentrism and contributed valuable insight into the movement of the planets. This included the first mention of the planets' elliptical paths and the change of their movement to the movement of free floating bodies as opposed to objects on rotating spheres. It is recognized as one of the most important works of the scientific revolution.
Document 8: James Gregory (mathematician): James Gregory FRS (November 1638 – October 1675) was a Scottish mathematician and astronomer. His surname is sometimes spelt as Gregorie, the original Scottish spelling. He described an early practical design for the reflecting telescope – the Gregorian telescope – and made advances in trigonometry, discovering infinite series representations for several trigonometric functions.
Document 9: Transit of Venus: A transit of Venus across the Sun takes place when the planet Venus passes directly between the Sun and a superior planet, becoming visible against (and hence obscuring a small portion of) the solar disk. During a transit, Venus can be seen from Earth as a small black disk moving across the face of the Sun. The duration of such transits is usually several hours (the transit of 2012 lasted 6 hours and 40 minutes). A transit is similar to a solar eclipse by the Moon. While the diameter of Venus is more than 3 times that of the Moon, Venus appears smaller, and travels more slowly across the face of the Sun, because it is much farther away from Earth.
Document 10: Transit of Venus, 2004: The second most recent transit of Venus observed from Earth took place on June 8, 2004. The event received significant attention, since it was the first Venus transit after the invention of broadcast media. No human alive at the time had witnessed a previous Venus transit since that transit occurred on December 6, 1882.
Document 11: 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.
Document 12: Roberts Ice Piedmont: Roberts Ice Piedmont ( ) is a large ice piedmont, 20 nautical miles (37 km) long in a north-south direction and 15 nautical miles (28 km) wide, lying to the north and northwest of Mount Calais and occupying most of the northeast corner of Alexander Island, Antarctica. It was first seen from a distance and roughly surveyed by the French Antarctic Expedition, 1908–10, under Charcot. It was photographed from the air by the British Graham Land Expedition (BGLE) on August 15, 1936, and roughly mapped from these photos. It was then named by the United Kingdom Antarctic Place-Names Committee (UK-APC) in 1955 after Brian B. Roberts (1912–78), a British ornithologist, polar specialist and leading figure in the development of Antarctic nomenclature; ornithologist, BGLE, 1934–37; Secretary, United Kingdom Antarctic Place-names Committee, 1945-74. About six nunataks are situated within the Roberts Ice Piedmont, these are Hengist Nunatak (a separate nunatak) and the Horsa Nunataks (a group of about five nunataks). Both of these features are named after Saxon kings of England in the fifth century; however, they have no association or relation with Brian B. Roberts and the Roberts Ice Piedmont itself.
Document 13: Adivar (crater): Adivar is an impact crater on Venus, named in honor of Turkish writer and pilot Halide Edip Adıvar. The crater is located just north of the western Aphrodite highland (9 degrees north latitude, 76 degrees east longitude). Surrounding the crater rim is ejected material which appears bright in the radar image due to the presence of rough fractured rock. A much broader area has also been affected by the impact, particularly to the west of the crater. Radar-bright materials, including a jet-like streak just west of the crater, extend for over 500 km across the surrounding plains. A darker streak, in a horseshoe or paraboloidal shape, surrounds the bright area. Radar-dark (i.e., smooth) paraboloidal streaks were observed around craters in earlier Magellan images, but this is a rare bright crater streak. These unusual streaks, seen only on Venus, are believed to result from the interaction of crater materials (the meteoroid, ejecta, or both) and high-speed winds in the upper atmosphere. The precise mechanism that produces the streaks is poorly understood, but it is clear that the dense atmosphere of Venus plays an important role in the distribution of the ejected material.
Document 14: Edmond Halley: Edmond (or Edmund) Halley, FRS (pronounced ; 8 November [O.S. 29 October] 1656 – 25 January 1742 [O.S. 14 January 1741] ) was an English astronomer, geophysicist, mathematician, meteorologist, and physicist who is best known for computing the orbit of Halley's Comet. He was the second Astronomer Royal in Britain, succeeding John Flamsteed.
Document 15: Donald B. Campbell: Donald B. Campbell is an Australian-born astronomer and Professor of Astronomy at Cornell University. Prior to joining the Cornell faculty he was Director of the Arecibo Observatory in Puerto Rico for seven years. Campbell's research work is in the general area of planetary studies with a concentration on the radio-wavelength-scattering properties of planets, planetary satellites, and small bodies. His work includes studies of Venus, the Moon, the Galilean satellites of Jupiter, Titan, as well as comets and asteroids. Campbell observed near-Earth asteroid 433 Eros, which was the first asteroid detected by the Arecibo Observatory radar system.
