Question: What Planet has a crater on it named after the man known in his lifetime as Gustavus Vassa?
Context: Sinan is an impact crater on the planet Mercury, 147 kilometers in diameter.  It is located at 15.5°N, 29.8°W, northeast of the crater Yeats and southeast of the crater Li Po.  It has one craterlet on the south-southwestern side of the crater floor, and it has a symmetrical pit slightly west of the center.  Together with a smaller unnamed crater on its southern border, the crater Sinan forms a shape similar to that of the spade found in card games.  The crater is named after Mimar Sinan, a 16th-century Turkish architect.  The name was adopted by the International Astronomical Union in 1976. 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. Dinorwic is a Martian impact crater, approximately 56 kilometers in diameter.  It is located on the planet Mars at 30.4°S, 101.6°W, northeast of the crater Virrat and north of the crater Tugaske.  To the northeast of Dinorwic is the crater Caxias, and farther north is the crater Llanesco.  It is named after the town in Ontario, Canada.  Its name was approved by the International Astronomical Union in 1991.  According to a surface age map of Mars based on US Geological Survey data, the area around Dinorwic is from the Noachian epoch, which places the area's age at 3.8 to 3.5 billion years ago.  At the crater's rim, it is about 7,600 meters above zero altitude, and it is about 5,950 meters above zero altitude at its floor, giving it a depth of 1.6 kilometers. Abu Nuwas is an impact crater on the planet Mercury, 116 kilometers in diameter.  It is located at 17.4°N, 20.4°W.  It is named after the Arab poet Abu Nuwas, and its name was approved by the International Astronomical Union in 1976.  There appears to be a small mountain centered inside the Abu Nuwas floor, and the crater's wall opens toward the south to link to a much smaller, unnamed crater.  To the north are the craters Ts'ai Wen-chi and Rodin.  To the southwest is the crater Moliere, and the crater Aśvaghosa can be found toward the south. Yeats is an impact crater on the planet Mercury, 100 kilometers in diameter.  It is located at 9.2°N, 34.6°W, south of the crater Li Po and southwest of the crater Sinan.  Its rim is circular and intact, except where an indentation is made by a craterlet on the north side.  It is bordered by a smaller, unnamed crater to the northwest.  On the otherwise featureless crater floor is a small, central mountain.  The crater is named after William Butler Yeats, an Irish poet and dramatist.  The name was adopted by the International Astronomical Union in 1976. Lermontov is an impact crater on the planet Mercury, 152 kilometers in diameter.  It is located at 15.2°N, 48.1°W, southwest of the crater Proust and northeast of the crater Giotto.  It has a circular rim and a flat crater floor.  Lermontov is likely a mature crater, but it remains a bright feature because of low opaque material on its floor.  The crater is named after Mikhail Yuryevich Lermontov, a 19th-century Russian poet.  The name was approved by the International Astronomical Union in 1976. Meteor Crater is a meteorite impact crater approximately 37 mi east of Flagstaff and 18 mi west of Winslow in the northern Arizona desert of the United States.  Because the United States Board on Geographic Names commonly recognizes names of natural features derived from the nearest post office, the feature acquired the name of "Meteor Crater" from the nearby post office named Meteor.  The site was formerly known as the Canyon Diablo Crater and fragments of the meteorite are officially called the Canyon Diablo Meteorite.  Scientists refer to the crater as Barringer Crater in honor of Daniel Barringer, who was first to suggest that it was produced by meteorite impact.  The crater is privately owned by the Barringer family through their Barringer Crater Company, which proclaims it to be the "best preserved meteorite crater on Earth". Olaudah Equiano (c. 1745 – 31 March 1797), known in his lifetime as Gustavus Vassa ( ), was a prominent African in London, a freed slave who supported the British movement to end the slave trade.  His autobiography, published in 1789, helped in the creation of the Slave Trade Act 1807 which ended the African trade for Britain and its colonies. Equiano is a crater on Mercury.  It has a diameter of kilometers.  Its name was adopted by the International Astronomical Union in 1976.  Equiano is named for the abolitionist writer Olaudah Equiano, who lived from 1750 to 1797. Molière is an impact crater on the planet Mercury, 132 kilometers in diameter.  It is located at 15.6°N, 16.9°W, south of the crater Rodin, southeast of the crater Abu Nuwas, and northeast of the crater Asvaghosa.  The nearly circular rim of the crater is cut off into a flat edge on its southern and southwestern ends, and on its eastern side the rim is indented by a smaller crater.  The crater is named for the 17th century French dramatist and satirist Molière.  The name was approved by the International Astronomical Union in 1976.
