Xi Ursae Majoris is composed of two main sequence dwarfs belonging to the spectral class G0 Ve. Xi Ursae Majoris is classified as an RS Canum Venaticorum type variable star. Polaris is the brightest star in the constellation of Ursa Minor. Peter Christoforou The combined visual magnitude of the system is 3.79. The brightest galaxy within this group is the well-known spiral Pinwheel Galaxy (also known as Messier 101). M82 was discovered by Johann Elert Bode on December 31, 1774, along with M81. A type Ia supernova, SN 1956A, was seen in the galaxy in 1956. The star has a apparent magnitude of 1.76 but an absolute magnitude of -0.26 when the star is viewed from a distance of 10 Parsecs or 32.6 Light Years. Pinwheel Galaxy – Messier 101 (NGC 5457) – photo: NASA, ESA (Hubble), K.D. The star’s traditional name, Alula Borealis, is derived from the Arabic word al-Ūlā, which means “the first (leap),” and the Latin word for “northern,” borealis.

It is also the brightest star in Ursa Major and the thirty-first brightest star in the sky. The Owl Nebula is a planetary nebula about 2,600 light years away from the solar system. The star’s traditional name, Phecda (or Phad), is derived from the Arabic phrase fakhð ad-dubb, which means “the thigh of the bear.”. – Mizar and Alcor (Zeta Ursae Majoris/ 80 Ursae Majoris) are perhaps the most famous naked eye double star in the night sky, and together are known as the “Horse and Rider.” They are both white stars approximately 80 light years away, with Mizar shining with a magnitude of 2.23, and Alcor at 4.01. The galaxy can be seen about 10 degrees northwest of the star Dubhe (Alpha Ursae Majoris). The constellation Ursa Major contains the group of stars commonly called the Big Dipper. However, when compared to the Milky Way with its hundreds of billions of stars, NGC 5474 does indeed seem relatively small. It is 14 times more luminous than the Sun and has 63% more mass. The other Messier Objects in Ursa Major includes the planetary Owl Nebula (M97) situated 1,630 light-years from Earth; and Winnecke 4 (M40), a faint double star found 510 light years away. The brightest star in Ursa Major is Alioth and is located about 128.87 light years from the Sun. Owl Nebula – Messier 97 (NGC 3587), photo: Jessica Barton, Faulkes Telescope North. Another consequence of the gravitational interactions is the vigorous star forming activity caused by interstellar gas falling into the centres of Messer 82 and NGC 3077. The distance between the two has decreased dramatically since, and is now only 4.5 arc seconds. Phecda – γ Ursae Majoris (Gamma Ursae Majoris), Gamma Ursae Majoris is the lower left star in the bowl of the Big Dipper. The star’s name, Megrez, is derived from the Arabic word al-maghriz, which means “the base” (as in, the base of the bear’s tail). Ursa Minor lies well away from the plane of the Milky Way, and does not contain any bright deep sky objects. Star formation that occurs in the galaxy’s core is ten times faster than star forming activity in the entire Milky Way. Find clues for Ursa Minor's brightest star or most any crossword answer or clues for crossword answers. It got its name because of its appearance of owl-like eyes when observed through a large telescope. Dubhe is the second brightest star in the constellation Ursa Major and the 33rd brightest star in the sky. It is also referred to as the “Plough” or “Frying Pan”, with four of its stars forming a pan shape, and the other three a handle. Two meteor showers are associated with it. It is a prominent pattern of bright stars and is circumpolar for mid-northern to polar latitudes in the Northern Hemisphere. Epsilon Ursae Majoris (Latinised from ε Ursae Majoris, abbreviated Epsilon UMa, ε UMa), officially named Alioth /ˈæliɒθ/, is, despite being designated "ε" (epsilon), the brightest star in the constellation of Ursa Major, and at magnitude 1.77 is the thirty-second brightest star in the sky. This time we are looking on the crossword puzzle clue for: Ursa Minor’s brightest star. Lalande 21185 is a red dwarf (spectral type: M2V) only 8.31 light years distant from the Sun. Alkaid is notable for being one of the hottest stars that can be seen without binoculars. Because of its relative proximity and brightness – it has an apparent magnitude of 6.94 – M81 is a popular target both for beginners and professional astronomers. If you are looking at the Big Dipper, the outer edge stars that make up the "bowl" of the dipper are the two stars, with Merak being the one on top. It is about six times more massive than the Sun, and 700 times more luminous. This is still very far, but many other constellation stars are over 200 light years away. Two of the stars, Dubhe and Merak, are pointer stars. It is believed to have formed about 8,000 years ago. Both Mizar and Alcor belong to the Ursa Major Moving Group. Xi Ursae Majoris is also notable for being the first binary star to have its orbit calculated, in 1828. The name Mizar is derived from the Arabic mÄ«zar, which means “girdle” or “waistband.”. Ursae Majoris (Eta Ursae Majoris). The galaxy’s apparent size is 26.9 x 14.1 arc minutes. Native North Americans also perceived the pattern of stars as a bear. Ursa Major . Muscida – ο Ursae Majoris (Omicron Ursae Majoris), Omicron Ursae Majoris is a multiple star system about 179 light years distant. The star’s traditional name comes from the Arabic word alyat, which means “fat tail of a sheep.” In 1779, Charles Messier identified the galaxy independently and included it in his catalogue. The constellation of Ursa Major is depicted on the flag of Alaska. The Pinwheel Galaxy is a grand design spiral galaxy seen face-on. – Alkaid (Eta Ursae Majoris) is a blue-white main sequence star situated 101 light-years from our solar system with a visual magnitude of 1.85. The brightest star of this constellation is Alioth, Epsilon Ursae Majoris. Hera was annoyed the pair were given so much honor and so convinced Poseidon to forbid them from bathing.

The constellation of Ursa Major never sets below the horizon. Not finding the nebula, Messier catalogued the binary star instead. Winnecke 4 is another binary star in Ursa Major. Charles Messier included it in his catalogue two years later. Kuntz (GSFC), F. Bresolin (University of Hawaii), J. Trauger (JPL), J. Mould (NOAO), and Y.H. Messier 108 is a barred spiral galaxy, discovered by Pierre Méchain in 1781. The Cigar Galaxy is believed to have had at least one tidal encounter with the neighbouring Messier 81 and, as a result, a large amount of gas ended up funneled into its core in the last 200 million years. M108 contains about 290 globular clusters and 83 X-ray sources. In about 19,900 years, it will come within 4.65 light years from the Sun. Bode’s Galaxy is the largest of the 34 galaxies in the M81 Group, one of the groups of galaxies located in Ursa Major.
