The zodiacal constellation, whose outline really resembles two human figures. The Castor represent the heads of twins whose bodies descend to the Milky Way and border Orion there
The “great twins” were called his Sumerians and Babylonians, but the bright stars were not named. In Greek mythology, the origin of the Gemini constellation is associated with the myth of the Dioscuri — Castor, and Polidevkei (Pollux). In the Australian dualistic mythologies of the tribes, the culices of the cultural hero Bungil and his brothers Paliane tell them that they live in heaven, and are identified with the stars of the constellation Gemini Castor and Pollux.
The twins occupy an area of 513.8 square degrees in the sky and contain 121 stars visible to the naked eye.
By designating stars in each constellation in Greek letters in descending order of light, Bayer made Castor the Alpha of the Twins, though he now shines weaker than Pollux. One of two: whether Pollux has become brighter since then, or whether Castor's brilliance has diminished. Or maybe Bayer was wrong.
Castor is a visual triple system, with both its bright components being spectrally double and the weak component a darkening double. So Castor is a tiny cluster of six stars. Their total apparent magnitude is 1.59 and the distance from the Sun is 45 years. And the magnitude of Pollux 1.16 and the distance of 35 st. years.
Castor and Pollux — the two main, most striking stars of the constellation of Gemini, judging by their names, must be very similar to each other. Nature, however, did not want to be reckoned with myths and endowed these stars with very different properties.
Castor is a multiple star, the two main components of which are blue hot stars. Castor is the 20th star in brightness. 66 Alpha Gemini, named after the hero of mythology, one of the brothers — Dioscuri. The apparent stellar magnitude is 1, 58 m. Spectral class A1 V. Castor is a six-star system.
Two binary systems (Castor A 1, 9 m visible A0 magnitude, rotating around its center in 9.2 days, and Castor B 2, 9 m visible A0 class magnitudes, generating 2.9 days) 4.1 “angle.
Even William Herschel in 1804 found in these components the orbital motion around the common center of mass (according to modern data, the period of rotation — 341 years). A third double component (Castor C, which rotates around its center in 0.8 days) is located approximately 73 “from the system described, having an average apparent value of 9.0 m.
The period of rotation of Castor C around the center of mass of the entire system is measured by tens of thousands of years. Each of these three stars is spectrally double (and Castor C is also darkened and variable) with periods: Castor A is 9 days; Castor B — 3 days; Castor C is 19 years old. The distance from the Castor system to the Sun is 14.3 pc. Astronomical position of centre of gravity for 2000,0: straight ascent = 07h34, 6 m; declension = + 31°53 '. The figure of the constellation Castor is on the head of the front Gemini.
By designating the stars in each constellation in Greek letters in descending order, Bayer made Castor the Alpha of the Twins, though he now shines weaker than Pollux. One of two: whether Pollux has become brighter since then, or Castor's brilliance has diminished. Or maybe Bayer was wrong.
On April 7, 2002, a very rare event occurred — covering the star of the constellation Gemini, the Pandora asteroid. The event was seen in Japan and the Far East. It began at 9: 39-9: 41 UT (13: 39-13: 41 in Moscow) — depending on the observation location. You could immediately see the passage of the eclipse. In the best places, Pollux's eclipse lasted up to 5 seconds.
The eclipse is truly unique: the first magnitude asteroid has never been observed in astronomy throughout the history of astronomy.
This event aroused the intense interest of specialists. At Hokkaido, the eclipse was the best place to watch — not only astronomers from all over Japan but also foreign experts, including from the US space agency NASA. According to scientists, the eclipse can present “quite unexpected opening”.
Gemini (21.05-21.06) — a sign of the elemental air. This is a sign of duality. Positive characteristics — gifted, inquisitive, agile, expressive. The negative qualities of Gemini are variability, superficiality, anxiety, they often do not bring to an end of the case. The keyword is “versatile development”.
Born under the sign of Gemini love change, both in small and respectable matters. They are almost always dissatisfied with the state of things now. A quiet, balanced life seems to them something unbearable. During the calm of life, the Twins begin to get bored and get sad. Worried about luck, they change the place of work, accommodation, environment, friends and likes at the first opportunity. Many Geminis can have a complete break-even moment in their lives, from which their whole lives move to a different path.
