AUSTIN, Texas — A quartet of stars has been discovered in an intimate cosmic dance, swirling around each other within a region about the same as Jupiter's orbit around the sun.

We tend to think of the North Star, Polaris, as a steady, solitary point of light that guided sailors in ages past. But there is more to the North Star than meets the eye. The North Star is actually a triple star system. And while one companion can be seen easily through small telescopes, the other hugs Polaris so tightly that it has never been seen – until now.

A scientist using NASA's Chandra X-ray Observatory has found evidence that two white dwarf stars are orbiting each other in a death grip, destined to merge.

Triple Star -- A triple star system consists of three gravitationally bound stars. The stars are in orbits around a common center of mass, usually so that two of the stars form a close binary star and the third is further away. This configuration is often called a hierarchical triple star. Multiple stars containing more than three stars can usually be decomposed to binaries and single stars that are in a hierachically bound system. ----- Click here to learn more on this...

Double Star -- When two stars are so nearly in the same direction as seen from Earth that they appear to be a single star to the naked eye but may be separated by the use of telescopes, they are referred to as a double star. There are two different kinds of double star. In the case where two stars are only apparently close to each other, but which are in fact separated by a great distance are known as optical doubles or optical binaries. In the vast majority of cases, however, the two...

Binary Star -- A binary star system consists of two stars both orbiting around a gravitational point between them. The term "binary star" was apparently first coined by Sir William Herschel in 1802 to designate "a real double star - the union of two stars that are formed together in one system by the laws of attraction." At present, binary stars are classified into three types according to their observable properties: visual binaries, spectroscopic binaries, and eclipsing binaries....

Proxima Centauri -- The red dwarf star Proxima Centauri (also Alpha Centauri C), part of the Alpha Centauri star system, is the nearest star to our Earth other than the Sun. Proxima Centauri is roughly 4.22 light years from Earth, 270,000 times as far as the sun. Its apparent magnitude is 11 (very weak, as red dwarfs in general are: far too weak to be observable with the naked eye). Proxima Centauri has often been suggested as a logical first destination for interstellar travel....

Alpha Centauri -- Alpha Centauri is the brightest star system in the southern constellation of Centaurus, and is the third brightest in the entire night sky (although too far south to be visible in most of the northern hemisphere). It is also the closest star system to Earth. It bears the proper name Rigil Kentaurus (often shortened to Rigil Kent), meaning "foot of the centaur" in Arabic, but is nonetheless usually referred to by its Bayer designation Alpha Centauri. Alpha Centauri is...
