It can be found close to the same path the Sun follows through the sky (the ecliptic), but can only be seen with a telescope. It could be between the fiction and reality too I guess. Wolf 359 is one of the nearest stars to the Sun; only the Alpha Centauri system, Barnard's Star, and the brown dwarfs Luhman 16 and WISE 08550714 are known to be closer. The best time of year to watch the stars and deep sky objects in Leo is during the spring months, when the constellation is prominent in the evening sky. Even though they would not appear close in the sky if they were visible, the two red dwarfs are separated by only 3.79 light years, which is less than the distance from the Sun to Proxima Centauri (4.2465 light years). Hephaestus Research Station, currently on Day 448 of its orbit around red dwarf star Wolf 359. Wolf 359 exhibited hundreds of flares in the K2 data, each more energetic than the Sun's Carrington flare, the . [42] The strength of this line can vary over a time period of several hours, which may be evidence of microflare heating. What is perhaps the most famous Star Trek planet was placed by creator Gene Roddenberry in a real star system: 40 Eridani. [51] Approximately 13,850 years ago, Wolf 359 was at its minimal distance of about 7.35ly (2.25pc) from the Sun. 50 light-years. Typically, the time scale for the spin down of a star at spectral class M6 is roughly 10 billion years, because fully convective stars like this lose their rotation more slowly than other stars.

Like other nearby stars, Wolf 359 is often used in works of fiction. The designation Gliese 406 (GJ 406 or Gl 406) comes from the Gliese Catalogue of Nearby Stars, published by the German astronomer Wilhelm Gliese in 1957. [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. The designation Wolf 359 comes from a 1919 catalogue of stars with high proper motions published by the German astronomer and astrophotography pioneer Max Wolf, who was the first to measure the stars proper motion in 1917. [33], A search of this star by the Hubble Space Telescope revealed no stellar companions. A high rate of proper motion can indicate that a star is located nearby, as more distant stars must move at higher velocities in order to achieve the same rate of angular travel across the celestial sphere. }) Sounds like the sun of Krypton. eventCategory: event.slot.getSlotElementId(), Given its relatively short distance from Earth of 31 light-years, Wolf 1069 b is now the sixth closest Earth-mass habitable zone exoplanet; the others are, in order of increasing distance, Proxima . 390 .

Why did the Borg use a cutting beam in "Best of Both Worlds" part 1 act III? [52], In June of 2019, an international team of astronomers led by Mikko Tuomi from the University of Hertfordshire, UK, submitted a preprint with the results of the first reported detection of two candidate exoplanets orbiting Wolf 359 using the radial velocity method from observations with HARPS in Chile and HIRES in Hawaii. It would take a spaceship 7.86 years travelling at the speed of light to get there. An easy way to see parallax is to place one finger at arms length and watch it jump back and forth when you view it successively with each eye, explain scientists. [6] This low rate of rotation may have been caused by loss of angular momentum through a stellar wind. Wolf 359 is located in the constellation Leo and has a magnitude of .

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. Wolf 359 was the first star other than the Sun to have the emission lines from its stellar corona observed from a ground-based telescope. 5.9630. These are equivalent to the Longitude and Latitude on Earth. - Age: 350 million years System: Akela and its planets are apparently named after lupine characters in an old Earth fiction work Jungle Book (the identity of the author, only . [24] By comparison, the magnetic field of the Sun averages 1gauss (100 T), although it can rise as high as 3kG (0.3 T) in active sunspot regions. 7.7825. So, to travel that distance at warp 9.9, it would be (7.2e13 / 913,878,914) / 3600 seconds = approximately 22 hours.
