In traditional astrological nomenclature, the stars were divided into fixed stars, Latin stellæ fixæ, which in astrology means the stars and other galactic or intergalactic bodies as recognized by astronomy; and "wandering stars" (Greek: πλανήτης αστήρ, planētēs astēr), which we know as the planets of the Solar System.
Consequently, a magnitude 1 star is about 2.5 times brighter than a magnitude 2 star, about 2.5 2 times brighter than a magnitude 3 star, about 2.5 3 times brighter than a magnitude 4 star, and so on. This is the modern magnitude system, which measures the brightness, not the apparent size, of stars.
This is the nearest red giant to the Earth, and the fourth brightest star in the night sky. Pollux (β Geminorum) 9.06 ± 0.03 [91] AD The nearest giant star to the Earth. Spica (α Virginis A) 7.47 ± 0.54 [97] One of the nearest supernova candidates and the sixteenth-brightest star in the night sky. Regulus (α Leonis A) 4.16 × 3.14 [98]
This astrology had some parallels with Hellenistic Greek (western) astrology, including the zodiac, a norming point near 9 degrees in Aries, the trine aspect, planetary exaltations, and the dodekatemoria (the twelve divisions of 30 degrees each). [31] The Babylonians viewed celestial events as possible signs rather than as causes of physical ...
The mass ratio of this planet with its star is more than 100 times greater than that of Earth and the sun. ... simply are not big enough to host planets much larger than Earth.
δ Leonis (Latinised to Delta Leonis) is the star's Bayer designation.. It bore the traditional names Zosma or Zozma and Duhr (rare spellings included Zozca, Zosca, Al-Zubra الزبرة, traditional Arabic for both shoulder, and a lion's mane and Dhur ظهر, the latter meaning 'back' in Arabic [citation needed]).
Our life-giving death star is experiencing its "solar maximum," which sounds like the name of a Christian rock band and is defined as the peak activity period within the sun's 11-year solar cycle.
The abundance of elements other than hydrogen and helium, what astronomers term the star's metallicity, is uncertain, with estimates ranging from 85% to 155% of the Sun's abundance. [ 11 ] [ 35 ] An old estimate for Pollux's diameter obtained in 1925 by John Stanley Plaskett via interferometry was 13 million miles (20.9 million km, or 18.5 R ...
