Aries 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 9 Extrasolar Planets (Exoplanets) in this constellation that are detailed on this site.

Aries Star and Deep Space Object Count

The number of stars that have been catalogued as part of the Hipparcos Star Catalogue from Aries is 966. The number of stars that are of magnitude 6.0 or lower in the constellation is 57. The number of stars in the constellation that make up the outline is 4.

There are no deep space objects that were identified by Charles Messier in this constellation. There are no non-Messier deep space objects in this constellation that are covered at present on this site.

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

Meteor Showers

There are 27 Meteor Showers that occur during the year within this constellation based on information gathered from Adam Mickiewicz University (Poland). The ones listed as the ones I've been able to find a date range for. For others if you have the time, you can visit the AMU site, obtains the SL value then use IMO tables to calculate the date. A lot of the Meteor Showers are weak and you need to do a lot of stargazing to spot them.

List of Named Stars in Aries without Extrasolar Planets

As there's so many stars in the cosmos, not all the stars are listed here. The site has lots of stars not listed so if your star isn't listed and you know the Henry Draper or Hipparcos ID, type https://www.universeguide.com/star/ then followed by the HIPNNNNNN or HDNNNN where NNNNN is the number part of the name. The stars that I do list have either a traditional name, a bayer or other classification name.
