Hephaestus Research Station, currently on Day 448 of its orbit around red dwarf star Wolf 359. 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). All three ships were diverted to . Difference between "select-editor" and "update-alternatives --config editor". While radio-tracking by NASAs Deep Space Network is far more accurate, its first use is a significant milestone in what may "someday become human exploration of the galaxy," say experts. } Wolf 359 is a relatively slow spinner, with a projected rotational velocity of less than 3 km/s. Some of those worlds may exist in its habitable zone, a region that allows liquid water to flow freely on planetary surfaces. [39] Numerous molecular bands appear in the spectrum of Wolf 359, including those of carbon monoxide (CO),[40] iron hydride (FeH), chromium hydride (CrH), water (H2O),[16] magnesium hydride (MgH), vanadium(II) oxide (VO),[14] titanium(II) oxide (TiO) and possibly the molecule CaOH. [18] He listed this star as entry number 359, and the star has since been referred to as Wolf 359 in reference to Max Wolf's catalogue. At 9.68 light-years . Home to the .

Notable stars in the constellation include Regulus (Alpha Leonis), the 21st brightest star in the sky, Algieba (Gamma Leonis), a binary system composed of two giants, the white giant Adhafera (Zeta Leonis), the carbon star CW Leonis, the white supergiant Eta Leonis, Icarus (MACS J1149 Lensed Star 1), one of the most distant stars known, and Caffaus Star (SDSS J102915+172927), one of the oldest stars known in the Milky Way with an estimated age of 13 billion years. [41] Since there are no lines of lithium in the spectrum, this element must have already been consumed by fusion at the core. [17][13], Wolf 359 first came to the attention of astronomers because of the relatively high rate of transverse motion against the background, known as the proper motion. . "The latest New Horizons stereoscopic experiment breaks all records. Because the absolute magnitude of a star is measured at a distance of 33 light years from Earth, and Wolf 359 is presently only about 7.8 light years away, Wolf 359's absolute magnitude is quite a bit fainter than its apparent magnitude, coming in at +16.64. However, only the rotational motion in the direction of the observer can be measured by this means, so the resulting data provides a lower limit on the star's rotation. hitType: 'event', It's called Barnard's Star, after American astronomer E.E. It could be between the fiction and reality too I guess. . Kadosca which just received extensive refit, Yamaguchi that patrol the outer Solar system and Galahand which was near the Wolf 359 at the time of gathering. Wolf 359 is a flare star, a variable star of the UV Ceti type that can undergo sudden increases in brightness across the spectrum. 12 Iconic Images From Hubble Space Telescope, How to Spot the Cassiopeia Constellation in the Night Sky, The Hercules Constellation: Location, Stars, Deep Sky Objects, There's a Starry Pooch in the Sky Named Canis Major, How to Find the Capricornus Constellation, Ph.D., Physics and Astronomy, Purdue University.
