Beta Arietis Sheratan is a blue-white star star with an apparent magnitude of 2. This star is also a spectroscopic binary, meaning that its companion is only known through analysis of the spectra.
Gamma Arietis Mesarthim is binary star with two white-hued components that are located light-years from Earth. Aries is also home to several faint Deep Sky Objects. These include NGC , an unbarred spiral galaxy located million light-years from Earth which is visible to the southeast of Beta Arietis.
It has a small companion galaxy, NGC , that is about , light-years away from the larger galaxy. Another spiral galaxy in Aries is NGC , a weakly barred spiral galaxy that is million light-years distant from Earth. For those who have a larger telescope, there are several faint galaxies that can be spotted. NGC is a good example, a 13th magnitude spiral galaxy located within Aries that is part of a galaxy group.
NGC is also part of a galaxy group and is equally faint, at magnitude NGC is a dwarf irregular galaxy that is considered to a Magellanic-type, with a larger than average core and a a H II nucleus containing zones of counter-rotating gas which is thought to be the result of tidal interactions with another gas-rich galaxy some time in the past. Aries is also home to several meteor showers. The May Arietids are a daylight meteor shower which begins between May 4th and June 6th with maximum activity happening on May 16th.
The Epsilon Arietids are also a daylight occurrence, which are active between April 25th to May 27th with peak activity on May 9th. The very best daytime Arietids occur from May 22nd to July 2nd with a maximum on June 8th, when the meteoroid stream produces one meteor every minute. Historically speaking, the Delta Arietid meteor shower was first noted in by analyzing photographic meteor orbits, and activity occurs between December 8th and December 13th.
The Autumn Arietid meteor shower begins on or about September 7th and runs through October 27th. Maximum activity occurs about October 8th, and the fall rate is about 3 to 5 average meteors per hour. Though representations of Aries as The Ram comes to us from classical antiquity, it is believed that this constellation has existed since the days of ancient Babylon. In the description of the Babylonian zodiac contained in the MUL.
The shift in identification from the constellation as the Agrarian Worker to the Ram likely occurred in later Babylonian tradition because of its growing association with Dumuzi the Shepherd. By the time the MUL. In traditional Chinese astronomy, stars from Aries were used in several constellations. This constellation has also been associated with harvest-time as it could represent a woman carrying a basket of food on her head.
Hamal has one known planet, which is a giant ball of gas similar to Jupiter, the giant of our own solar system. It's so close to Hamal that its atmosphere is being blown off into space. One of the ram's most important stars is too faint to see without a telescope.
Yet half a century ago, it played a key role in a revolutionary discovery: Most of the chemical elements on Earth -- and in our bodies -- were forged in the stars.
For a long time, scientists didn't know where the oxygen, silicon, iron, and other heavy elements that make up Earth came from. A faint star in Aries, HD , along with a star in Libra, helped point the way. In , astronomers reported that these two stars had much less iron and calcium than the Sun. It was a shocking report, because most astronomers thought that nearly all stars had the same composition. Around this time, though, they realized that the two iron-deficient stars were very old, so they had formed in the galaxy's earliest years.
Since the stars had little iron, it meant that the young galaxy itself had little iron. According to another Aries constellation story of Greek origin, King Athamas appointed his eldest son Phrixos as his successor to the throne. His current wife, Ino, however, wanted to see her own son in his place. For this reason, the conniving queen resorted to a ruse. She let the seed spoil for the following year, causing crop failure. He was told that if he wanted to avoid another crop failure in the following year, he would have to sacrifice his son Phrixos.
But high above the strait separating Europe and Asia, Helle fell into the sea, where she drowned. The ram flew on with Phrixos on his back to the land of Colchis, where the boy was well received. In astronomy, there is a celestial coordinate system for fixing positions of all celestial bodies. The First Point of Aries has been chosen as the zero point in the celestial sphere. It is the point at which the Sun crosses the Celestial Equator moving from south to north along the ecliptic.
However, due to precession, the vernal equinox now lies in the constellation Pisces. Hamal, also called Alpha Arietis, is the brightest star of constellation Aries. Hamal is a red giant located about 75 light years away from us. Sheratan, or Beta Arietis, is a binary star. It means that it includes two stars: a white main sequence star and a spectroscopic binary, 66 light years distant.
Mesarthim, also known as Gamma Arietis, is a triple star system. Mesarthim lies about light-years away from us. Delta Arietis, or Botein, the following brightest star after Alpha, Beta and Gamma Arietis, is an orange giant star located approximately light years from Earth. This name is derived from the Arabic word butain, which means 'belly'.
