TANIA AUSTRALIS (Mu Ursae Majoris). Our Ursa Major, the Greater Bear, contains remnants of ancient Arabic constellations, the best-known example the star Alkaid, which refers to the leader of the daughters of a funeral est of the Dipper's bowl lie three obvious pairs of stars that represent the bear's paws, but to the Arabs were the tracks of leaping gazelles. Star Trek (–). 61 Ursae Majoris is orbited by the class M planet Archer IV. AD (), role-playing game designed by the Game Designers' Workshop. Home system of Joi, a habitable garden world that has four ethnic colonies (Azanian, British, German, and Japanese), as well as the free nation of Elysia, a former French colony.

The Constellation Ursa Major - The Great Bear. Ursa Major is one of the most well known constellations in the heavens. It contains the famous grouping of stars known as the Big Dipper, which is often the first group of stars learned by people in the northern hemisphere.
Fun with double and variable stars. belong to double or multiple star systems. In some cases, a dwarf star is revolving around a giant sun. Below's a sample chart showing Z Ursae Majoris. The third star in the system is a red dwarf of the spectral type M1V, separated from the main pair by arc seconds. The three stars share a common proper motion. They are suspected to be members of the Ursa Major Moving Group. The system lies some 46 light years from Earth. BY Draconis. BY Draconis is another multiple star in Draco.

Kappa Ursae Majoris (κ Ursae Majoris, abbreviated Kappa UMa, κ UMa) is a binary star in the constellation of Ursa a combined apparent magnitude of +, the system is approximately light-years from Earth.
The two components are designated Kappa Ursae Majoris A (officially named Alkaphrah / æ l ˈ k æ f r ə /, a traditional name of the system) and llation: Ursa Major. Well, there’s one more twist to the tale of Xi Ursae Majoris. The total mass of the system is known to a great degree of precision at solar masses.
Not only has a Bc companion been suggested, but a NASA’s WISE mission revealed earlier this year that a T-type brown dwarf shares a common proper motion with the Xi Ursae Majoris system.
Xi Ursae Majoris (HR /5) consists of a visual binary having a period of nearly 60 yr, the primary component of which is a day astrometric and spectroscopic subsystem, and the secondary is. 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 main components are separated by only arcseconds. Xi Ursae Majoris is a splendid binary, one of the most attractive in Ursa Major: xi UMa (Struve ), two yellow stars, AB:; º, " with an orbit of years.
From xi UMa and nu UMa move one binocular field north: Lalande is barely visible in the southwestern corner. Once, it was a generation ship, carrying one and a half million colonists from Earth through the emptiness of space to the distant worlds of the Xi Ursae Majoris system.
Then came the Crisis. During the anarachy that followed, most of the ship's crew perished, while others mutated into 5/5(1).
Muscida – ο Ursae Majoris (Omicron Ursae Majoris) Omicron Ursae Majoris is a multiple star system about light years distant. It belongs to the spectral class G4 II-III, which means that it is somewhere between a giant and bright giant on the evolutionary scale. It has an apparent visual magnitude of Muscida – ο Ursae Majoris (Omicron Ursae Majoris) Omicron Ursae Majoris is a multiple star system about light years distant.
It belongs to the spectral class G4 II-III, which means that it is somewhere between a giant and bright giant on the evolutionary scale. It has an apparent magnitude of 47 Ursae Majoris c is known as Wolf,and there are two fictional terrestrial planets, Fox and Raven, which orbit inward from Bear and Wolf.

Cambridge Core - Astrophysics through Computation - by Brian Koberlein. VII The Multiple System Xi Ursae Majoris. Astrophysical Journal, (January ), Book summary views reflect the number of visits to the book and chapter landing pages.
Total views: *Cited by: 1. AE Ursae Majoris is a short-period, high-amplitude delta Scuti star, a pulsating variable close to the main sequence. The delta Scuti stars, once given the moniker "dwarf Cepheids", are stars slightly more massive than our Sun that pulsate with periods of 1 to 6 hours.
Z Ursae Majoris (Z UMa) Z UMa is a circumpolar variable star visible from the northern hemisphere, is easy to find, and high in the springtime sky. Z UMa is sometimes bright enough to view with binoculars, but at other times you need a telescope.
These Astronomical objects span the categories of Exoplanets, Brown Dwarfs, Stars by Spectral type, Populations, Luminosity Classes and by Stellar Evolution, Variable Stars, Compact Stars and Gamma Ray Bursts. This list is adapted from the Wikipedia article titled "Astronomical Objects". I ran across a source that called every "nearest star" in each constellation "Proxima" followed by the constellation name, for example "Proxima Canis Majoris" was Sirius.
This automatically gives us 88 names, mostly to very dim but important stars. Lalande becomes "Proxima Ursae Majoris" and and Ross becomes "Proxima Andromedae".

Another system that I like to re–visit in summer twilight is Lambda Cygni (″), which is easier to resolve than 78UMa, as the components are more closely matched in terms of their.

(v) Griffin's () paper on Xi Ursae Majoris. I certainly learned about Xi as I read his treatment of this star system. He was quite thorough--down to Admiral Symth's challenge that Xi is the Bear's "right hind paw," not the "left hind foot" as originally reported by Sir William Herschel when he discovered the double-star in This galaxy can be seen with the unaided eye -- it is the furthest object that can be seen with the naked eye, it is million light years from Earth.
It was known to the Persian astronomer Abd-al-Rahman Al-Sufi who described it in his book Book of Fixed Stars in A.D. It is visible in both the Northern and Southern hemispheres. There are four stars in the system.  Additional names for the Talitha system are Iota, Ursae, Majoris, and Dnoces.

In the table below, unless indicated by a "†", the "modern proper name" is that approved by the WGSN and entered in the List of IAU-approved Star Names or otherwise approved by the IAU.
The WGSN decided to attribute proper names to individual stars rather than entire multiple systems. For such names relating to members of multiple star systems, and where a component letter (from e.g.
