Stars

With the Wolfram Stars Reference App, youll have access to real-time data on over 100,000 stars. Compute your favorite stars sky position, find out when it will rise next, and perform advanced calculations. - For easy browsing, stars are sorted into groups such as the Northern or Southern Sky Stars; Brightest Stars; Nearest Stars; and Giant, Supergiant, and Main Sequence Stars - The Star Lookup allows you to enter any star name in the input field - Examine and compare properties for each star, such as its magnitude, spectral class, temperature, mass, lifetime, and distance from Earth - See the stars position on the Hertzsprung–Russell diagram - Compute the stars current sky position from your location, find out whether it is visible, and learn the times of the stars next rise and set - Perform advanced astronomical calculations using the Stefan–Boltzmann law, Wiens displacement law, blackbody luminosity, and mass-luminosity relationship The Wolfram Stars Reference App is powered by the Wolfram|Alpha computational knowledge engine and is created by Wolfram Research, makers of Mathematica—the worlds leading software system for mathematical research and education. The Wolfram Stars Reference App draws on the computational power of Wolfram|Alphas supercomputers over a 2G, 3G, 4G, or Wi-Fi connection.
