Nearest F-type main sequence star with a multiplanetary system. Second-brightest star in the night sky with a multiplanetary system after 7 Canis Majoris. All exoplanets orbit around star A in the binary system. 47 Ursae Majoris: Ursa Major: 10 h 59 m 27.97 s +40° 25′ 48.9″ 5.10: 46: G0V: 1.029: 5892: 7.434: 3

The discovery of 20 previously unknown star systems within 10 parsecs of the Solar System. These are in addition to 8 new star systems announced between 2000 and 2005. [4] RECONS is listed explicitly as an author on papers submitted to the Bulletin of the American Astronomical Society since 2004. [5] The RECONS web page includes the frequently ...
This category contains articles about star systems, which are groups of two or more gravitationally-bound stars in a region usually smaller than one light-year. Star clusters (groups of many more stars that occupy a much larger region) are listed in Category:Star clusters.
Optical companions (stars that appear to be close together but are physically unrelated) do not count. Star systems placed here should be categorized by their number of components. Trinary star systems are listed under Category:Triple star systems, while binary stars are listed under Category:Binary stars
"All-America teams" do not typically play any games as a unit, unlike many of the all-star teams. [ citation needed ] The original use of the term "All-America" seems to have been in reference to a list of college football players who were regarded as the best at their respective positions.
The first All-Star Game was held as part of the 1933 World's Fair at Comiskey Park and was the brainchild of Arch Ward, then sports editor for the Chicago Tribune. [1] Initially intended to be a one-time event, its great success resulted in making the game an annual event, with some years (1959–1962) having two All-Star Games.
A multiple star system consists of two or more stars that appear from Earth to be close to one another in the sky. [dubious – discuss] This may result from the stars actually being physically close and gravitationally bound to each other, in which case it is a physical multiple star, or this closeness may be merely apparent, in which case it is an optical multiple star [a] Physical multiple ...
