The Leo Constellation | Pictures, Facts, and Brightest Stars The 2005 study examined the effects of the rotation for the first time using the CHARA telescope array on top of Mount Wilson in California. The two stars complete an orbit around their common centre of mass every 40 days or so. This is not only the best golf resort in the area, but actually one the best in the country. The star is an exceptionally fast rotator, with a rotation period of only 15.9 hours. The pair lie about 177 arc seconds or 4,200 astronomical units away from Regulus A. Regulus B has an apparent magnitude of 8.13 and Regulus C has an apparent magnitude of 13.50. The stars Altair and Achernar are also fast spinners with flattened, oblate shapes.

Regulus is the only 1st magnitude star to sit almost squarely on the ecliptic, which marks the path of the sun, moon and planets across our sky. It is approximately 70 million light years distant. However, Regulus C would require a larger telescope to be seen isolated from the system. It has a visual magnitude of 4.1 and is about 133 light years distant from Earth.

The stars heliacal rising, which is its first appearance above the horizon after a period of invisibility, occurs in the first week of September for observers in most locations. Regulus was seen as the main star because it was in the constellation of Leo, giving it the power of the lion, signifying the strength of kings with large implications. A line from Megrez through Phecda, the inner stars of the Big Dippers bowl, leads to the Sickle. Together, the Regulus BC pair can be seen in small telescopes. These are minor objects in the inner Solar System. There are no recently available measurements. Draco) or exist in the real world (e.g. Leo constellation lies in the northern sky.

According to Bantu Mythology mankind is not indigenous to planet Earth. Archaeological evidence suggests that Mesopotamians had a constellation similar to Leo as early as 4000 BC. The central region of M95 has a ring-shaped starburst region around the core with a diameter spanning about 2,000 light years. In 2016, the International Astronomical Union organized a Working Group on Star Names (WGSN)[21] to catalog and standardize proper names for stars. The main star Regulus A is large and blue with a spectral type of B8 IVn. If we go across the sea to Egypt, we can see a different take on the constellation Leo myth. A constellation is a pattern of stars in a recognisable shape that is supposed to resemble an object, animal or person. [4] Spica - Alpha Virginis - Constellation Guide The Sickle can be found using the bright stars of the Big Dipper, the most recognizable part of the constellation Ursa Major. The Planets. Regulus, the brightest star in the constellation Leo, the lion, is a harbinger of spring in the Northern Hemisphere. Leo Constellation: Stars, Facts, Myth, Location - Constellation Guide It can be seen in the night sky throughout the year except for a month on either side of August 22, when the Sun comes too close to the star. Our Sun in comparison has an average temperature of 5.778 Kelvin. It would also be the star system from which the lions and the lion Gods (half man, half human) originally came. For example, in 1959, Regulus was occulted by Venus. Due to the stars oblate shape, its poles are closer to the centre of mass and have a higher effective temperature and therefore brightness, while the equatorial region is cooler and less bright. in Space Studies from the University of North Dakota, a Bachelor of Journalism from Canada's Carleton University and a Bachelor of History from Canada's Athabasca University. There is a great deal of mythology associated with Leo, perhaps the most common tale being that Leo was the Nemean Lion of the Hercules story. In the Babylonian MUL.APIN, Regulus is listed as Lugal, meaning king, with co-descriptor, "star of the Lion's breast".[41].

As for what causes the rapid rotation, astronomers at the time said it was a mystery. Marissa B. Goodyear, AZ. It has a visual magnitude of 3.856 and is approximately 5,000 light years distant. As a result, the star is emitting polarized light. It was discovered by the German astronomer Albert Marth on April 5, 1864. [27] The next will occur on October 1, 2044, also by Venus. The star was listed as one of four "royal stars," first under the name Venant and then Miyan ("the center", according to the Encyclopedia of Astronomy and Astrophysics.).

M66 and NGC 3628 had an encounter in the past, and the gravitational interaction between the two resulted in an exceptionally high central mass concentration in M66, a high molecular to atomic mass ratio, and a resolved noncorotating clump of H I material being removed from one of M66s spiral arms. Regulus was associated with Jupiter and Mars, and linked with granite and mugwort. Gliese 436 is another red dwarf located relatively close to the Sun. It has a visual magnitude of 10.8 and is a member of the Leo II Group (NGC 3607 Group) of galaxies. The two stars take approximately 40 days to complete an orbit around their common centre of mass. This fast rotation causes Regulus A to bulge at its equator, so it appears oblate, or egg-shaped. 3.52), and Rho Leonis (mag. Don became interested in astronomy at age 8. In 1978, Don was one of the independent inventors of the Messier Marathon, an attempt to find and view all 110 galaxies, clusters, and nebulae in one night.
