Aries, The Ram Constellation

Aries (Pronounciation:Air-ees, Abbrev:Ari, Latin:Arietis) is a constellation, one of 88 constellations that the night sky is divided into. The sky is not divided up equally between the constellations. Aries takes up 441.395 sq. degrees of the night sky which equates to 1.07% of the night sky. The constellation gets its name as it name means The Ram . The constellation is one of the original constellations that was devised by the Ancient Greco-Egyptian astronomer Ptolemy who lived between 90 A.D. and 168 A.D.

Aries is a member constellation of the Zodiac grouping, a group of 12 star signs that astrologers use to predict someones future based on their date of birth and which constellation appeared when the Sun set. The Zodiac year may be divided up equally between the twelve signs but when they appear in the night sky no longer conforms to the Zodiac calendar. Aries is an equatorial constellation that can be seen by countries nearest the Equator.

The brightest star in Aries is Hamal. There are 15 Extrasolar Planets (Exoplanets) in this constellation that are detailed on this site. There is a dedicated page for exoplanets in Aries. For a list of named stars, that is stars that don't start HD or HIP, please visit Aries Star List Page.

Stars of Interest

The nearest star to Earth is HIP 12781 which is roughly about 24.49 Light Years from the Earth. The nearest star to the Earth with an exoplanet is Hamal which is about 65.81 Light Years. The furthest star that can be located in the constellation is HIP 15713 which is located about 108721.1 Light Years away from the Sun. The furthest figure is derived from either the 1997 or 2007 Hipparcos star catalogue parallax figure and it has been known to produce distances that are wrong.

The dimmest star that can be seen in Aries with the naked eye is 29 Arietis. The dim star has an apparent magnitude of 6. The dimmest star that a person is able to see with their naked eye is 6.0 magnitude based on the table in the reference. Ref: University of Michigan

The caveat of these stars are that they are catalogued on this site. If you know of a star that is nearer or further then do let me know in the comments and I'll add it to the site. The stars mentioned are from the Hipparcos catalogue or have been added because of their special status.

Legend of the constellation

Athamas's son Phrixus and daughter Helle was carried by Aries to Colchis so that they could escape their stepmother Ino. Phrixus made it to safety but Helle fell into some water and became Hellepoint. Once Phrixus was safe, he sacrificed the Ram, its fleece was flung onto a Grove of Ares. The fleece turned to gold. Jason and the Argonauts sought out this fleece for its healing properties.

Hamal Planets

Hamal is one of those rare stars that is an Alpha star and has stars in orbit round it. The other stars that spring to mind are Aldebaran in the nearby constellation of Taurus and Fomalhaut, the Alpha star in Piscis Austrinus. Just because the star is an Alpha star doesn't mean that the planet will or will not have life on the planet, we just don't know. Of what can be seen i

There are no major meteor showers that radiate from within this constellation.
