An error, in the 13th century AD, reading the Arabic ya as ba led to the European name. The traditional name Betelgeuse has been derived from the Arabic يد الجوزاء Yad al-Jauzā’ "the hand of al-Jauzā’ ". The star's designation is α Orionis (Latinised to Alpha Orionis), given by Johann Bayer in 1603. This cast material millions of miles from the star that then cooled to form the dust that caused the star's dimming. A study using the Hubble Space Telescope suggests that occluding dust was created by a surface mass ejection. Infrared observations found no significant change in luminosity over the last 50 years, suggesting that the dimming was due to a change in extinction around the star rather than a more fundamental change. ![]() It then returned to a more normal brightness range, reaching a peak of 0.0 visual and 0.1 V-band magnitude in April 2023. Starting in October 2019, Betelgeuse began to dim noticeably, and by mid-February 2020 its brightness had dropped by a factor of approximately 3, from magnitude 0.5 to 1.7. The Earth-observed angular diameter of Betelgeuse is exceeded only by those of R Doradus and the Sun. It is also surrounded by a complex, asymmetric envelope, roughly 250 times the size of the star, caused by mass loss from the star itself. Subsequent studies have reported an angular diameter (i.e., apparent size) ranging from 0.042 to 0.056 arcseconds that range of determinations is ascribed to non-sphericity, limb darkening, pulsations and varying appearance at different wavelengths. In 1920, Betelgeuse became the first extrasolar star whose photosphere's angular size was measured. Having been ejected from its birthplace in the Orion OB1 association – which includes the stars in Orion's Belt – this runaway star has been observed to be moving through the interstellar medium at a speed of 30 km/s, creating a bow shock over four light-years wide. Less than 10 million years old, Betelgeuse has evolved rapidly because of its large mass and is expected to end its evolution with a supernova explosion, most likely within 100,000 years. For various reasons, its distance has been quite difficult to measure current best estimates are on the order of 500–600 light-years from the Sun – a comparatively wide uncertainty for a relatively nearby star. ![]() Calculations of Betelgeuse's mass range from slightly under ten to a little over twenty times that of the Sun. If it were at the center of our Solar System, its surface would lie beyond the asteroid belt and it would engulf the orbits of Mercury, Venus, Earth, and Mars. Its Bayer designation is α Orionis, Latinised to Alpha Orionis and abbreviated Alpha Ori or α Ori. At near-infrared wavelengths, Betelgeuse is the brightest star in the night sky. It is a distinctly reddish, semiregular variable star whose apparent magnitude, varying between +0.0 and +1.6, has the widest range displayed by any first-magnitude star. ![]() It is usually the tenth-brightest star in the night sky and, after Rigel, the second-brightest in the constellation of Orion. Lists every NPC in Classic WoW and lets you link through to them to see their location on the map./ ˈ b ɛ t əl dʒ uː z, ˈ b iː t əl-, - dʒ uː s/ īetelgeuse, α Ori, 58 Ori, HR 2061, BD+7☁055, HD 39801, FK5 224, HIP 27989, SAO 113271, GC 7451, CCDM J05552+0724, AAVSO 0549+07īetelgeuse is a red supergiant star of spectral type M1-2 and one of the largest visible to the naked eye. The dynamic results will show you if we have any locations for that NPC denoted by the number next to the icon.Ĭreated a new NPC Location Listing page (added ot the menu at the top). The NPC panel has been upgraded to allow some specific filtering, you can now search accross the world for any NPC you desire. We've extended our database to include the location of many more creatures within the world, search for them in the NPC panel, click the one you're looking for to see detailed locations. You can now click on any icon on the map be it Vendor, Quest Marker, Inn Keeper etc, an appropriate help panel will popup showing additional information. Right click anywhere on the map to show everything close by, including any NPCs and gathering nodes.Īdded a filter on the herb / mining tab to only show gathering nodes / veins relevant to your required location. Works exactly the same as the old one but covers so much more :) ![]() New map that includes all current and future expansions. Latest WoW Classic Map Features NEW MAP - ONE FOR ALL
