Draco, The Dragon Constellation

Draco Constellation Star Map

Draco (Pronounciation:Drac-o, Abbrev:Dra, Latin:Draconis) is a constellation, one of 88 constellations that the night sky is divided into. The sky is not divided up equally between the constellations. Draco takes up 1082.952 sq. degrees of the night sky which equates to 2.63% of the night sky. Draco is the 8th largest in terms of size in the night sky.

The constellation name means The Dragon . 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.

There are 13 stars that make up the main constellation. The hipparcos satellite scanned and detailed 2689 stars. There are 121 stars that can be seen with the naked eye in the constellation on a very clear night sky.

Draco is not a member of the Zodiac group of twelve constellations that appear when the Sun sets. Draco is a northern hemispheric constellation which means it can't be seen easily or at all from the southern hemisphere.

There are 150 Extrasolar Planets (Exoplanets) in this constellation that are detailed on this site. There is a dedicated page for exoplanets in Draco.

There are no deep space objects that were identified by Charles Messier in this constellation. There are 2 non-Messier deep space objects that are covered on this site and the list is below.

Distance to Draco

You can't just go to one location and arrive at the constellation because the constellation is made up of stars at different locations and different distances. The nearest main star in the constellation is at a distance of 26.28 light years and the furthest main star is a distance of 490.47 light years. The average distance to the main stars is 188.39 light years.

Draco Star Facts

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.

Struve 2398 B, Draco's Nearest Star

The nearest star to Earth is Struve 2398 B which is roughly about 11.27 Light Years from the Earth. The nearest star to the Earth with an exoplanet is Edasich which is about 101.2 Light Years.

HIP 57123, Draco's Furthest Star

The furthest star that is located in the constellation is HIP 57123 and it is 163081.7 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.

Eltanin, Brightest Star in Draco

The brightest star in Draco is Eltanin and is located about 68.95 light years from the Sun. The star has a apparent magnitude of 2.24 but an absolute magnitude of -1.13 when the star is viewed from a distance of 10 Parsecs or 32.6 Light Years. The star is only recognised as being Gamma Draconis rather than having Alpha status.

HIP 63340, Draco's Dimmest Visible Star

The dimmest star that can be seen in Draco with the naked eye is HIP 63340. 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.

Thuban

Thuban was once the Pole star but as our star and planets moved, Thuban moved out of position. Thubans loss, Polaris's gain so to speak. Thuban may one day regain its title but not in the near future.

How to Find and View Draco in the Night Sky

Northern Hemisphere

Draco is one of four constellations that can be seen all the year round in the Northern Hemisphere. There is no best or worst time for it. The only thing that could affect your viewing is light and exactly where you are in the Northern Hemisphere. The constellation can be seen soon after dark It will stay in a northern direction. Over night, it will seemingly spin on its axis before returning back to its original position for the next day.

Southern Hemisphere

As Draco is so far north, it is not possible to see it at any time of the year, at least from Sydney, Australia. There's more than enough other constellations that are available to keep you occupied to look at.

Draco Mythology

There are said to be two possible stories behind this constellation. The first is that the Dragon that fought Minerva during the wars between the Gods and the Giants. The Dragon got there because it lost the fight with Minerva and was thrown into the heavens.

The other story is that it is the dragon that Hera put in the Garden of Hesperidia's to protect the golden apples. The apples grew on a tree given to her as a wedding present by Gaia. Hercules slayed the dragon by throwing a spear into the garden. Atlas retrieved the apples for Hercules who took them to Eurystheus.

Meteor Showers Radiating from Draco
