One complete orbit takes 365.256 days (1 sidereal year), during which time Earth has traveled 940 million km (584 million mi). [2] Ignoring the influence of other Solar System bodies, Earth's orbit, also called Earth's revolution, is an ellipse with the Earth–Sun barycenter as one focus with a current eccentricity of 0.0167. Since this value ...

Mercator's 1569 map was a large planisphere, [3] i.e. a projection of the spherical Earth onto the plane. It was printed in eighteen separate sheets from copper plates engraved by Mercator himself. [4]
'A Map of the Myriad Countries of the World'; Italian: Carta Geografica Completa di tutti i Regni del Mondo, "Complete Geographical Map of all the Kingdoms of the World"), printed by Italian Jesuit missionary Matteo Ricci at the request by Wanli Emperor in 1602, is the first known European-styled Chinese world map (and the first Chinese map to ...
Schöner's 1515 map of America re-drawn on an equirectangular projection and on the same uniform scale as that of Waldseemüller of 1507, so as to be readily comparable. [6] Apparently most map-makers at the time still erroneously believed that the lands discovered by Christopher Columbus, Vespucci, and others formed part of the Indies of Asia
Geosynchronous orbit (GSO): An orbit around the Earth with a period equal to one sidereal day, which is Earth's average rotational period of 23 hours, 56 minutes, 4.091 seconds. For a nearly circular orbit, this implies an altitude of approximately 35,786 kilometers (22,236 mi). The orbit's inclination and eccentricity may not necessarily be zero.
The Fra Mauro map, completed around 1459, is a map of the then-known world. Following the standard practice at that time, south is at the top. The map was said by Giovanni Battista Ramusio to have been partially based on the one brought from Cathay by Marco Polo. This is a chronology of the early European exploration of Asia. [1]
The map is very large – the full frame measures 2.4 by 2.4 metres (8 by 8 ft). This makes Fra Mauro's mappa mundi the world's largest extant map from early modern Europe. The map is drawn on high-quality vellum and is set in a gilded wooden frame. The large drawings are highly detailed and use a range of expensive colors; blue, red, turquoise ...
