Draco (constellation)

The Egyptian Pyramids were designed to have one side facing north, with an entrance passage geometrically aligned so that Thuban would be visible at night.

The brighter of the three, and the brightest star in Draco, is Gamma Draconis, traditionally called Etamin or Eltanin.

Nearby Beta Draconis, traditionally called Rastaban, is a yellow giant star of magnitude 2.8, 362 light-years from Earth.

Nu Draconis is a similar binary star with two white components, 100 light-years from Earth.

Psi Draconis (traditionally called Dziban[3]) is a binary star divisible in binoculars and small amateur telescopes, 72 light-years from Earth.

[1] NGC 6543 has a very complex shape due to gravitational interactions between the components of the multiple star at its center, the progenitor of the nebula approximately 1,000 years ago.

In long-term exposures, IC 4677 appears as a portion of a ring surrounding the planetary nebula.

It acts as a gravitational lens for even more distant background galaxies, allowing astronomers to study those galaxies as well as Abell 2218 itself; more specifically, the lensing effect allows astronomers to confirm the cluster's mass as determined by x-ray emissions.

The light of Q1634+706 has taken 8.6 billion years to reach Earth, a discrepancy attributable to the expansion of the universe.

[4] The Hercules–Corona Borealis Great Wall, possibly the largest known structure in the universe, covers a part of the southern region of Draco.

Gaius Julius Hyginus in De Astronomica reports that it was one of the Gigantes, who battled the Olympian gods for ten years in the Gigantomachy, before the goddess Athena killed it and tossed it into the sky upon his defeat.

[11][12] Aelius Aristides names him Aster or Asterius ('star' or 'starry') and says that Athens' Great Panathenaea festival celebrated Athena's victory over him.

[14] The Catasterismi attributed to Eratosthenes identify Draco as Ladon, the dragon who guarded the golden apples of the Hesperides.

[12] Traditional Arabic astronomy does not depict a dragon in modern-day Draco, which is called the Mother Camels.

The nomads who own the camels are camped nearby, represented by a cooking tripod composed of Upsilon, Tau, and Sigma Draconis.

During the 2011 outburst, ZHR reached 400 meteors/hour, however it was largely unnoticed visually due to interference by the bright Moon.

[21] Draco was a United States Navy Crater class cargo ship named after the constellation.

At the conclusion of the film, Draco, the last dragon, ascends into the constellation after he sacrifices himself to destroy an evil king.
