The Voyager 2 probe will actually make a close pass within 1.7 light-years of the star in about 40,000 years. Below is a tabular view of the star facts with the values of the Sun on the right so you can compare them against our star, the Sun. [35][36] Radial velocity measurements of this star using the Near Infrared Spectrometer (NIRSPEC) instrument at the Keck II observatory have not revealed any variations that might otherwise indicate the presence of an orbiting companion. Even though it is close by, you won't be able to see it because it is faint. Like Wolf 359, it is classified as a flare star. The absence of lithium indicates that the element must have been used up by the fusion in the stars core and that the star is at least 100 million years old. Since the Earth-Sun distance is 15 meters in the Voyage model, a basketball-size Earth would require an Earth-Sun distance of about 3 kilometers, and a Sun-Pluto distance of about 120 kilometers.)

Only objects with a magnitude of 6.5 or less can be seen on a clear night. [Hint: how is parallax angle related to distance.] I also think StarTrek.com may be under reporting the distance from Wolf 359 to Earth a little. It was also the site where Captain Benjamin Sisko lost his wife during the battle. The star Wolf 359 is 7.86 light-years from Earth. No one has visited Wolf 359, and we have no probes on a rendezvous with the star. The star is actually moving so fast through space that in about 36,000 years, it will actually take over the title as the closest star to Earth (besides our Sun) for about 9,000 years. There is a relationship between colour and temperature, stars that are closer to red in the rainbow spectrum are cooler whereas those closer to blue are hotter. Wolf 359 - 7 .

It is known more commonly as the Dog Star. Wolf 359 cannot be seen from the Earth with the naked eye, it is just too far and too dim to be seen. What is perhaps the most famous Star Trek planet was placed by creator Gene Roddenberry in a real star system: 40 Eridani. Calculate how many miles away it is. The shift seen in Proxima Centauri (left) and Wolf 359 (right). It's not visible to the naked eye. Temperature estimates of the photosphere of Wolf 359 range from 2,500K to 2,900K,[38] which is sufficiently cool for equilibrium chemistry to occur. Wolf 359 is a relatively young star with an age of less than a billion years. The Proxima Centauri image was obtained on April 22 by a remotely operated 0.4-meter telescope at the Siding Spring node of the Las Cumbres Observatory in Australia. [16] The surface has a magnetic field that is stronger than the average magnetic field on the Sun. The Hubble Space Telescope was recently used to search for faint companions about Wolf 359. The Sun's radius is 695,800km, therefore, the star's radius is an estimated 111,328.km. Based on the spectral type as we don't have the exact temperature', we can deduce that the surface temperature of the star is in the order of below 3,500K based on the notes from Harvard University. One planetary companion is suspected, with another candidate planet having been found to be a likely false positive, but as yet no debris disks have been found. 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 magnitude assumes nothing is between the object and the viewer, such as dust clouds. Unfortunately, it appears to have none.
