Yaks have handlebar horns, shoulder humps, horse-like tails and long shaggy skirts hanging nearly to the ground. Yaks can live up to 20 years and more. Cows average about 600-800 pounds and around 4.5 feet at the hump. Bulls average 1200-1500 pounds but can reach over 1600 pounds.
Brightness of stars is assigned a number starting with the brightest star starting at about -1 magnitude. Dimmer stars are zero or positive numbers. The larger the number means the dimmer the star is. For example, a star -1 magnitude is brighter than a star 0 magnitude. A star 0 magnitude is brighter than a star 1 magnitude. A star 1 magnitude is brighter than a star 2 magnitude. A star 4 magnitude is brighter than a star 5 magnitude. Magnitude sequence for stars starting with the brightest is -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 magnitude, ... etc. The decimal point is not used when star magnitudes are used on a star map. The decimal point could be confused for a star on the map.
Hamal â Î± Arietis (Alpha Arietis). Hamal is the brightest star in the constellation Aries and the 48th brightest star in the night sky. It is a K-type orange giant about twice as massive as the Sun, with an apparent visual magnitude varying between 1.98 and 2.04. The star is 66 light years distant.GC 772, or Arp 78, is an unbarred spiral galaxy in Aries. It is located about 130 light years from Earth and has an apparent magnitude of 11.3. The galaxy lies southeast of Beta Arietis. Two supernovae were discovered in the galaxy, SN 2003 hl and SN 2993 iq.
