In Indian astronomy, Regulus corresponds to the Nakshatra Magha ("the bountiful"). Regulus is a quadruple star system composed of four stars organized into two pairs. The Arabic phrase is sometimes approximated as Kabelaced. As a result, the star is emitting polarized light. s r.o. The star is a very fast spinner, with a projected rotational velocity of 318 km/s at the equator. They, of course, did not know that this star was actually a quadruple star system. It can also be occulted by Mercury and Venus, but this only happens rarely. Regulus is situated in one of the most prominent asterisms known as the Sickle of Leo. 0-120°C Contact thermometer, retaining spring, d=63mm, 0-120°C Thermometer, with sheath (l= 30, 3/8“), rear, d=40 mm. The heliacal rising of Regulus (rising just before the dawn after a period of invisibility) occurs in early September. 2.98), Chertan (Theta Leo, mag. This blue-white star has a companion, though the pair is technically k… The location of the main sequence star in the night sky is determined by the Right Ascension (R.A.) and Declination (Dec.), these are equivalent to the Longitude and Latitude on the Earth. Regulus is a multiple star system consisting of at least four stars. The star was also known as Basiliskos, Cor Leonis – Lions heart. It would take a spaceship 77.49 years travelling at the speed of light to get there. Regulus, Alpha Leonis, α Leo, 32 Leonis, HR 3982, HIP 49669, FK5 380, GJ 9316, GCTP 2384.00, α Leo A, HD 87901, SAO 98967, LTT 12716, BD+12°2149, TYC 833-1381-1, GC 13926, GCRV 6417, α Leo B/C, HD 87884, SAO 98966, LTT 12714, BD+12°2147, TYC 833-134-1, GC 13922, GCRV 6416, PPM 127133, Gaia DR2 3880785530720066176, Gaia DR1 3880785526425032832. The primary pair, Regulus A and Regulus B are separated by a distance of around 0.40 AU. Does Jerry Seinfeld have Parkinson's disease? Regulus C is a Binary or Multiple star system. [4] Designated Regulus B and Regulus C, the pair has Henry Draper Catalogue number HD 87884. Because of this, it has a rotational period of around 15.9 hours and it is emitting polarized light. On March 20, 2014, the star was occulted by 163 Erigone, a relatively large asteroid first discovered in April 1876. If the R.A. is positive then its eastwards. Regulus is 79 light-years / 24 parsecs distance away from the Sun. Regulus C has an apparent magnitude of 13.50 which is how bright we see the star from Earth. 2.56), Epsilon Leonis (mag. Regulus B and Regulus C have an orbital period of 600 years. 3.33), Eta Leonis (mag. It is spinning extremely rapidly, with a rotation period of only 15.9 hours, which causes it to have a highly oblate shape. It is only slightly fainter than Deneb in the constellation Cygnus and Mimosa in Crux, and it just outshines Adhara in Canis Major, Castor in Gemini, and Shaula in Scorpius. It has a lower mass than our sun, at around 0.8 solar masses. The asteroid 166 Rhodope, discovered in August 1876, was observed occulting Regulus by a team of researchers on October 19, 2005. The second binary pair of stars, designated Regulus CD, is around 5.000 AU away from the primary pair. Regulus A has an average temperature of around 12.460 Kelvin. It was the Polish astronomer and inventor of the heliocentric system Nicolaus Copernicus who gave the star its name.
