The primary component, Eta Cassiopeiae A, has only 0.972 solar masses, or 97.2% of our Suns mass, thus it is slightly lighter. In 2007, Hipparcos data was revised with a new parallax of 33.62000 which put Alpheratz at a distance of 97.01 light years or 29.74 parsecs. Found inside Page 73A line from Aldebaran through Algol , at the distance of 28 degrees from Algol , will intersect Schedar , a star of the Sirius is the brightest star in the heavens , and is by some astronomers supposed to be nearest the earth . No. The distance from Caph to M52 is roughly the same as the distance between Caph and Schedar. Zeta Cassiopeiae is a Slow Pulsating B star that was discovered to have a magnetic field and is located around 600 light-years away. Alpheratz is the 55th brightest star in the night sky and is the brightest star in Andromeda based on the Hipparcos 2007 apparent magnitude. +2.3. Schedar was thought to have three stellar companions, all of which are too close to the star to be easily seen. Absolute magnitude (M) is a measure of the luminosity of a celestial object, on an inverse logarithmic astronomical magnitude scale. Scientists believe Earth and its moon formed around the same time as the rest of the solar system. Found insideSince the stars appear to rotate around the Earth once every 24 hours , Right Ascension is measured eastward - anti Declination measures ( in degrees ) a star's angular distance above or below the celestial equator . MAX melurs Gamma Cassiopeiae has a mass 17 times that of the Sun and, as it ended its main sequence lifetime, it has expanded to a size of 10 solar ra The supernova of 1572 is again placed in the Cassiopeia constellation, and at a similar distance: at around 11000 light-years from the Solar System. The image on the preceding page was created to demonstrate that Alpha Centauri is not a star, but really a star system. 50 Cassiopeiae is a star in the constellation Cassiopeia. This star gives you an idea what our Sun would look like when placed at a distance of 19 light years. Completely revised and updated, this new edition provides a readable, beautifully illustrated journey through world cultures and the vibrant array of sky mythology, creation stories, models of the universe, temples and skyscrapers that each Found inside Page 151APPENDIX J Name Pronunciation Bayer name Origin of name Meaning of name Distance Acamar Achernar Acrux Adhara Aldebaran their meanings ( usually related to their constellations ) , and their distances in lightyears from earth . db Shedir / Schedar / Alpha Cassiopeiae: is a second magnitude star in the constellation Cassiopeia, with the traditional name Schedar, sometimes spelt Shedir.

Based on the spectral type (B9p) of the star, the Alpheratz colour is blue . Achird / Eta Cassiopeiae is located at around 19 light-years away from the Sun. Eta ~ e and HD 93129A, two of the most massive and luminous stars in our Milky Way galaxy, are among them. Hourglass Nebula Hourglass Nebula Eta ~ e star system revealed in unprecedented detail If you want to measure the distance from one point on the Earth to another, you should use the great-circle or orthodromic distance formula. The answer is yes. At 316 light-years distant, Canopus is over 37 times as far away from the Earth as the number one star on our list, Sirius. The separation is 65 arc seconds. It is the distance that light travels in 1 year. Messier 52 (M52) is a bright open cluster located in the northern constellation Cassiopeia. When I punched in the katakana for Schedar into the rest of J-Wiki, I was ultimately taken to the English Wikipedia to the article for the star in the constellation of Cassiopeia known as Alpha Cassiopeiae. The star is running out of the supply of hydrogen in its core and is on its way to evolving into a giant. The five brightest stars in Cassiopeia make up the W. Schedar, the brightest, is a four-star system, dominated by a large, orange-colored star with over 700 times the luminosity of the Sun. As punishment, its said, she is chained to a chair and hangs upside-down. Found inside Page 46 8S and 1W of Schedar (a Cas) Best Months: August to December in N. Hemisphere Distance: 2.5 million light-years 17 and 18 are often discussed together, as they are similar-sized dwarf galaxies at the same distance from Earth. Telescopically, stars have been mapped, photographed and catalogued almost completely down to the 11th magnitude. HIP677 is the reference name for the star in the Hipparcos Star Catalogue.

The catalogue was started by the American doctor and has been expanded on over the years. At best, you get pulled into a very long and slow orbit (the Sun takes about a quarter of a billion years for one orbit).
