    Alioth – ε Ursae Majoris (Epsilon Ursae Majoris) Alioth is the brightest star in Ursa Major and the 31st brightest star in the night sky. It has an apparent visual magnitude of and is approximately 81 light years distant. The star’s traditional name comes from the Arabic word alyat, which means “fat tail of a sheep.” Alioth is the. Located just west of the Crown. Arcturus, its brightest star, is about 30° southeast of η Ursae Majoris. Virgo: Spica, its brightest star, is located by a line drawn from Antares in Scorpius through α in Libra and prolonged about 20°. Canes Venatici: Cor Caroli, its brightest star, is about 17° south of Alioth in Ursa Major.

    Distance and visibility. 47 Ursae Majoris is located fairly close to the Solar System: according to astrometric measurements made by the Hipparcos astrometry satellite, the star exhibits a parallax of milliarcseconds, corresponding to a distance of light-years. [1] With an apparent magnitude of +, it is visible to the naked eye under good conditions. Ursa Major is a constellation that can be seen in the northern hemisphere and part of the southern hemisphere. Its name means Great Bear in was named that because many different groups of people around the world have thought that its stars look a lot like a bear with a long of the stars in the constellation except Dubhe and Alkaid are moving toward the same Symbolism: the Great Bear.

    Epsilon Ursae Majoris (Alioth) is the brightest star in the constellation Ursa Major. It has a spectral type of A0, so it will be a white giant. Asked in Jobs & Education, Physics, Chemistry.   If you know them, you can specify the station's distance from it's host start (--ls-from-star or --ls for short), indicate whether it has a black market (--blackmarket or --bm with a value of 'Y' if you know it has a black market or 'N' if you know it doesn't) or specify the maximum pad size the station supports (--pad with a value of 'S' for small, 'M' for medium or 'L' for large).

Z Ursae Majoris is a semiregular variable. Semiregular variables are post main sequence cool (red) giant and supergiant stars. They are classified as long period variables (LPVs), commonly called red variables, and occupy a distinct zone in the far.

Properties. Based upon parallax measurements, β Ursae Majoris is located at a distance of light-years ( parsecs) from the is a subgiant, a star that has exhausted the hydrogen in its core and is now cooling as it generates energy through the thermonuclear fusion of hydrogen in a shell outside the core.

The effective temperature of the outer envelope is about 9, K, Constellation: Ursa Major. Gamma Ursae Majoris (γ Ursae Majoris, abbreviated Gamma UMa, γ UMa), formally named Phecda / ˈ f ɛ k d ə /, is a star in the constellation of Ursathe spectrum of this star has served as one of the stable anchor points by which other stars are classified.

Based upon parallax measurements with the Hipparcos astrometry satellite, it is located at distance of Constellation: Ursa Major. Our Lady of 47 Ursae Majoris and Other Stories - Kindle edition by Parks, Richard.

There is also second spectroscopic companion located 8 minutes of arc away from the primary star, which is a 7th magnitude F8-type star listed as Alpha Ursae Majoris C (HD ).

In addition to the primary pair, another binary system is located ab astronomical units away, which makes Dubhe a 5-star system. Mizar (Zeta Ursae Majoris), image: Wikisky. Star system. The Zeta Ursae Majoris star system consists of two pairs of spectroscopic binary stars appearing as a visual double star.

The system is an excellent target for small telescopes. The two. Megrez, Delta Ursae Majoris (δ UMa), is the faintest of the seven stars that form the Big Dipper asterism.

Of the Ursae Majoris tales, the title story is the standout, a quiet, poetic meditation on one of the planet’s archaeological mysteries, and the effect it has on beings of two different species. If any story in the collection deserves having the book named after it, it’s this one. Ursa Major is a constellation that can be seen in the northern hemisphere and part of the southern hemisphere.

Alioth (Epsilon Ursae Majoris), despite its “epsilon” tag, is the most luminous star in Ursa Major but only just since at magnitude + it is a mere 2% brighter than the star Dubhe, the second brightest star in the ed light years from Earth, this blue star is also the 33rd brightest star in the entire night sky, and is listed as one of the 57 navigational stars.

Ursa Major (Latin: "Larger She-Bear"; also known as the Great Bear) is a constellation visible throughout the year in most of the northern hemisphere. It can be seen best in the month of April. It is dominated by the widely recognized asterism known as the Big Dipper or the Plough, which is a useful pointer towards the north, and it has.

Another star, W Ursae Majoris, is an even closer neighbor, only light years away, which places it practically right across the street from us in the galactic neighborhood.

Ancient people thought it was shaped like a bear and that’s exactly where its name comes from as it means The Big Bear in ancient Greek. In astronomy, Ursa Major is also referred to as Ursae Majoris and the stars that form it are named with that label.
