... May 26, 1996 . Alpha Centauri: The Closest Star System . ... Explanation: The closest star system to the Sun is the Alpha Centauri system . ... The bright stars Alpha Centauri A and B form a close binary as they are separated by only 23 times the Earth - Sun distance - slightly greater than the distance between Uranus and the Sun . ... Alpha Centauri A, also known as Rigil Kentaurus , is the brightest star in the constellation of Centaurus and is the fourth brightest star in the night sky. ...

... 2000 January 10 . Brown Sun Bubbling . ... Our Sun is an extremely large ball of bubbling hot gas , mostly hydrogen gas. The above picture was taken in a specific color of light emitted by hydrogen gas called Hydrogen-alpha . ... The energy source of our Sun is the nuclear fusion of hydrogen into helium deep within its core. Astronomers are still working to understand, however, why so few neutrinos are measured from the Sun's core. ... About APOD | ...

... The distance scales of the objects are matched both by comparing the first derivatives of the angular velocity determined separately from radial velocities and proper motions and by the statistical-parallax method. ... Good agreement between the inferred 0 and our calculations based on space velocities suggests that the Lindblad relation holds throughout the entire sample volume. ... Brandt and Blitz (1993) published the distances and radial velocities for a total of 206 H II-regions. ... Astron. ...
