A third star, Proxima Centauri (sometimes called Alpha Centauri C), is gravitationally associated with the former. . The real Wolf 359 is a flare star that modern scientists have determined is a red dwarf, spectral class M6, massing 0.093 of Sol with absolute magnitude +16.56. Which one was it and why did it survive? If the name seems familiar then its probably you've heard it in Star Trek - The Next Generation as it was the scene of a battle between the Federation and a Borg Cube which didn't end well for the Federation. At present there are no known companion bodies orbiting Wolf 359. What is the bloodiest war in the Star Trek universe involving the UFP? NASA probe captures images of our nearest stars appearing to be in different positions than seen from Earth. "The New Horizons experiment provides the largest parallax baseline ever made over 4 billion miles and is the first demonstration of an easily observable stellar parallax," said Tod Lauer, New Horizons science team member from the National Science Foundation's National Optical-Infrared Astronomy Research Laboratory, who coordinated the parallax demonstration. No large orbiting body (stellar or substellar, such as a brown dwarf) were found as close as the distance from the Earth to the Sun -- i.e., one AU -- from Wolf 359 (Schroeder et al, 2000). 7.780.04 light-year. The companion images of Proxima Centauri and Wolf 359 were provided by different institutes. Wolf 359 was given the variable star designation CN Leonis after the first detection of a flare from the star in 1969, which led to its classification as a flare star. The timing accounts for New Horizons being nearly three light hours closer to Proxima Centauri than Earth when the images were taken. The constellations brightest star Regulus marks the celestial Lions heart, the stars of the Sickle outline the mane, Zosma and Chertan the rump, and Denebola the tail. If we were to send a lightsail satellite out to this system, it would likely encounter Proxima first. Back to Wolf 359, 7.6 light years is approximately 7.2e13 km.
