Rudolphine Tables and instructive examples for computing planetary positions. For most stars these tables were accurate to within one arc minute, and included corrective factors for atmospheric refraction. The tables were sufficiently accurate to predict a transit of Mercury observed by Pierre Gassendi in 1631 and a transit of Venus observed by Jeremiah Horrox in 1639. Rudolphine Tables The Rudolphine Tables () consist of a star catalogue and planetary tables published by Johannes Kepler in 1627, using some observational data collected by Tycho Brahe (1546–1601). The tables are named as "Rudolphine" in memory of Rudolf II, Holy Roman Emperor. Star tables had
Stars and planetary systems in fiction by 75 times in only 20 seconds. None of the items below pretend that UV Ceti is orbited by habitable worlds. Wolf 359 is a red dwarf of apparent magnitude 13.5 and thus can only be seen with a large telescope. However, at approximately 7.8 light-years away it is the fourth-closest stellar system to the Sun; only the Alpha Centauri system, Luhman 16 and Barnard's Star are known to be closer. Thus, even though it is suspected to be a flare star, it has attracted the attention of science fiction authors, filmmakers, and game developers. Stars and planetary systems in
