Misor and Alcor are a famous double star system located in the Big Dipper constellation. They are actually two separate stars that appear close together in the night sky, and have been used historically as a visual test for eyesight.
Alcor is a hot, white A5V main sequence star having a luminosity about 13 times that of the sun. The spectral type implies that Alcor has an effective temperature of 8500 K, a diameter 1.7 times that of the sun, and a mass of about 2.2 solar masses. Alcor is a variable star of Delta Scuti type; see Caph.
The apparent visual magnitude of the star Alcor is about 4.01, making it faintly visible to the naked eye under good viewing conditions. Its apparent brightness may vary slightly depending on atmospheric conditions and light pollution in the observer's location.
The star Alcor has a very specifis color,it is a whitish orange star which means its kind of cool, but you never know. So i would recommend for you to go on http:/Googlo.com or Yahoo.com Images to look for it.
the archaic word Mizar means cloak.in astronomy, it refers to a star in the handle of the Big Dipper.its located near Alcor in the the handle of the Big Dipper.And are actually a complex system. Alcor is a binary and Mizar is a quadruple system of two binary stars.
Mizar and Alcor are in a sextuplet system in the constellation Ursa Major.Mizar of Zeta Ursa Majoris (actually 4 stars) is one of the stars in the asterism "the Big Dipper" or "the Plough".Alcor or 80 Ursa Majoris is a binary system that is orbiting the Mizar Systrem.All 6 stars are also part of the Ursa Major Moving Group.Mizar A Sytem - Distance from earth 78 light years. Orbit each other every 20 days 12 hours and 55 minutes.Mizar A-A - Spectral type A2 V.Mizar A-B - Spectral type A2 V.Mizar B System - Seperation from Mizar A - 380 AU. Orbital period with Mizar A of many thousands of yearsMizar B-A - Spectral type A1 V.Mizar B-B - Spectral type A7 V.Alcor System - Seperation from Mizar 74,000 AU.Alcor A - Spectral Type A5 V.Alcor B - Spectal Type M? V. Red dwarf.
Ursa Major is the constellation that contains Alcor.
The population of Mairena del Alcor is 19,924.
The area of Mairena del Alcor is 69.72 square kilometers.
The population of Alcor Life Extension Foundation is 12.
El Viso del Alcor's population is 18,351.
Santa Cecilia del Alcor's population is 152.
The Alcor star which resides in URSA MAJOR, part of the star that makes up the big Dipper, is 81 light years from earth. FYI: Alcor and Mizar are twin stars or double stars which almost line up directly behind each other. However, Alcor is behind Mizar but resides slightly above and to the left of Mizar.
Alcor is a binary star system located in the Big Dipper constellation. The primary star, Alcor A, is a main sequence star with a mass about 1.9 times that of the Sun and a radius around 1.75 times that of the Sun. The companion star, Alcor B, is a smaller red dwarf star.
Alcor is a hot, white A5V main sequence star having a luminosity about 13 times that of the sun. The spectral type implies that Alcor has an effective temperature of 8500 K, a diameter 1.7 times that of the sun, and a mass of about 2.2 solar masses. Alcor is a variable star of Delta Scuti type; see Caph.
The double star in the handle of the Big Dipper is called Alcor and Mizar. They are also known as Mizar and Alcor.
