The Sun comes close to Aldebaran around June 1 every year.About 5,000 years ago, Aldebaran was close to the vernal equinox, the instant when the Sun crosses the celestial equator, marking the beginning of spring in the northern hemisphere.
The star came within 21.5 light years of the solar system and, at its maximum, was slightly brighter than Aldebaran is the fourth brightest star in the sky in near-infrared wavelengths. Aldebaran is the brightest star in the region between the Belt and the Pleiades. It is the brightest star in Taurus constellation and the 14th brightest star in the night sky. Alpha Tauri D, E and F have apparent magnitudes of 13.70, 12.00 and 13.60. The epoch photometry of the Hipparcos catalogue indicates that the star’s brightness varies by only 0.02 magnitudes over a possible period of about 18 days. Aldebaran, Alpha Tauri, also known as the Eye of Taurus, is an orange giant star located at a distance of 65 light years from Earth. Its brightness varies from magnitude 0.75 to 0.95 according to historical records given in the General Catalogue of Variable Stars (GCVS). Each star was connected with a plant and a gemstone – in Aldebaran’s case, milk thistle and ruby – and these would be used in rituals to bring out the star’s influence.The space Probe Pioneer 10, launched in 1972, is headed in the general direction of the star. It is an 11th magnitude star separated by 117’’ from Aldebaran. Aldebaran lies at a distance of 65.3 light years from Earth and is in the same line of sight as the bright Hyades open cluster. The Aldebaran is one of the two stars in Taurus included on the list of the 58 navigational stars.
Aldebaran is also one of the 33 stars used as benchmarks to calibrate the stellar parameters during the Gaia space observatory mission (2013 – 2022), launched to take precise astrometric measurements and create the largest 3D space catalogue of the Milky Way to date.The surface gravity of Aldebaran is 1.59 cgs, about 25 times lower than our planet’s and 700 times lower than the Sun’s, but not unusual for a giant star.Aldebaran lies only 5.47 degrees south of the ecliptic, the Sun’s apparent path across the sky, and can be occulted by the Moon. Aldebaran, the "fiery eye of the Bull", is a star system in Taurus that is considered to be a home of the Anunnaki (Illojiim). It has exhausted the hydrogen supply in its core and, as it evolved off the main sequence, it started to expand to its current size. Aldebaran is the brightest star in the constellation Taurus and is known as the "Eye of Taurus."
Aldebaran is the 14th brightest star in the night sky and is the brightest star in Taurus based on the Hipparcos 2007 apparent magnitude.
Aldebaran is a giant star of the spectral type … It narrowly outshines In medieval astrology, Aldebaran was one of the 15 Behenian fixed stars, believed to be a source of special astrological power, and it was associated with the planets Venus and Mars. These include the Crab Nebula (Messier 1), a historic supernova remnant, Hind’s Variable Nebula (NGC 1555), a young reflection nebula illuminated by the variable pre-main sequence star T Tauri, the Crystal Ball Nebula (NGC 1514), a planetary nebula that made William Herschel reconsider his beliefs about the starry nature of these objects, and the colliding galaxies NGC 1410 and NGC 1409.The best time of year to observe the stars and deep sky objects of Taurus is during the month of January, when the constellation rises high in the evening sky.The 10 brightest stars in Taurus are Aldebaran (Alpha Tau, mag. The stars that form the Winter Hexagon are Aldebaran, Aldebaran lies in the same line of sight as the Hyades, the nearest open star cluster to Earth.
