For the southern hemisphere, constellations appear rotated degrees upside-down and left-right reversed from what is shown. Remember that seasons are reversed too - summer in northern latitudes is winter in southern latitudes. Values listed apply primarily to stars. Deep-sky objects such as galaxies and nebulae are diffuse, so subtract an integer for these. Galaxy name Alt name Magnitude Draco Dwarf This bridge is a source of debate between astronomers. Using the redshift theory, if a bridge does exist, then the distance between the two objects would be much closer Exoplanets are planets that revolve around stars, other than our star, the Sun.
Exoplanets excite astronomers as they may offer conditions similar to those in our Solar System, with the possibility of life. The Draco dragon constellation has a large number of exoplanets — 97 in total so far!
Iota Draconis is a yellow-white double that lies about It has one planet in its orbit, known as HIP b. This discovery was in HD is a yellow-white main-sequence star. It has 2 exoplanets orbiting around it. HD b has an orbital period of days. Its mass is 2. Its discovery was in Kepler is a G-type star with a radius of 0.
Kepler b is a Neptune-like exoplanet, with a mass of It takes Kepler b is a Neptune-like exoplanet that orbits its mother star every It has a mass of is Kepler is a G-type star, light-years away from earth.
It has 2 exoplanets orbiting it. The first is Kepler, a Neptune-like exoplanet with a mass of 6. It takes 6. Kepler c is a Neptune-like exoplanet with a mass of Meteor showers occur when Earth crosses the orbital path of a comet.
This creates a spectacular show, often known as shooting stars. The meteor shower occurs between 6 October and 10 October with a peak on 8 October. This is a spectacular shower to observe in the northern hemisphere — a huge dragon spitting out fireballs!
In the southern hemisphere, Draco the constellation is difficult to see, as it barely rises above the horizon, so your chance of spotting shooting stars is very low. The comet linked to the Draconids is the Giacobini-Zinner comet. In years where the Earth passes closest to the debris of the comet, thousands of meteors can be seen.
The Draconid meteor shower produced amazing displays in and , and observers saw over meteors per hour in The radiant of the shower is the point from where it originates. The Draconids appear to radiate outwards from the fiery mouth of the Dragon.
The two brightest stars in Draco, Eltanin, and Rastaban are the eyes of the dragon and are close to the radiant point of the Draconids. This is a minor shower that occurs between 3 February and 5 February, with the peak on 4 February. The Draconis constellation is a large constellation with many bright stars, and you can easily spot it without a telescope.
Then, you can imagine the mythical dragon, with a twisted snake-like shape, winding his way across the heavens. Where is Draco in the sky? Draco is a northern constellation and is the 8th largest constellation in the 88 named constellations.
It occupies an area of square degrees. Draco lies in the third quadrant of the northern hemisphere, NQ3. A quadrant is essentially a quarter of a circle, which allows astronomers to measure the altitude of objects above the horizon. To find the Draco constellation location, you can locate the two Dipper star patterns, or asterisms, known as the Big Dipper and the Small Dipper. They lie in the constellations of Ursa Major and Ursa Minor. The twisted body of Draco, winds its way between these two constellations.
Another tip to find the head of the red dragon constellation is to locate Hercules the Kneeling Giant Warrior. The two bright stars, Rastaban and Elatin, are the eyes of the Dragon, glaring directly at the warrior As a home stargazer, you may ask — when is Draco visible?
Here is one of the fascinating Draco constellation facts — the Dragon is only fully visible in the northern hemisphere! In the southern hemisphere, you will only see a small part of the dragon, very low on the horizon. In the northern regions the constellation Draco never sets below the horizon, so you can see it all year round. From January to March the dragon first appears low on the horizon in a northerly direction at about 6pm.
This is a great time to take the kids out for some amazing stargazing. In April, May, and June, Draco appears in a more north-easterly position at about 9pm. At 2am, he is directly overhead and then sinks down towards the northwest horizon. In July, August, and September, the constellation is visible directly overhead at about 10pm. From October to December, drako the dragon appears high in the sky in the northwest at about 6pm and moves overhead at about midnight.
A great time to plan a romantic midnight feast and experience some dragon magic. In the southern hemisphere, the dragon constellations are only partly visible in the months of July, August, and September. Look very low on the northern horizon at around 7pm. You may spot a part of the twisted body before he vanishes at midnight. Draco constellation with his head facing Heracles and his body winding between Ursa Minor and Ursa Major.
If you live in the Southern Hemisphere, you may ask — how to find the Draco constellation? You will find it difficult to spot the star dragon! He only dips very slightly onto your horizon, and only a small part of his twisted body may show.
You will have to plan a stargazing vacation with the family to see the Draco star system. Draco is the 8th largest constellation in the sky. It has bright stars that are easy to spot in dark skies.
By locating these stars, you can imagine the twisted dragon Draco circling in the skies. Like all stargazing experiences, getting away from city lights is the best way to see constellations and deep-sky objects. You can see the Drago constellation with the naked eye, but using a telescope will make it so much more exciting.
For amateurs, there is a great choice of well-priced scopes that will give you fabulous images of Draco in the sky. It has a computerized mount that automatically tracks your celestial object as it moves across the sky.
The scope comes with 2 eyepieces, a 25mm, and a 9mm. Just pick an object and it aligns for you. It features a 3. The scope weighs only 12 lbs and is great to take along on a family outing for stargazing. The design is very impressive — it totally eliminates cord-wrap issues.
Ursa Major sits between degrees north latitude. Therefore, the further south your position the lower it will appear in the north sky. Above latitudes of 45 degrees north the constellation remains above the horizon at all times. Best visible at in July. January : visible 15 degrees above the northern horizon from The constellation rotates anticlockwise around the north star. It is 45 degrees above the northern horizon at sunrise.
February : visible 15 degrees above the northern horizon from It reaches near to its peak 50 degrees above northern horizon at sunrise. March : visible 15 degrees above the northern horizon from It reaches its peak 55 degrees above northern horizon at sunrise.
April : visible 15 degrees above the northern horizon from It reaches its peak 55 degrees above northern horizon at before lowering to 50 degrees by sunrise. May : visible 30 degrees above the northern horizon at sunset.
Making it visible throughout the night. June : visible 45 degrees above the northern horizon at sunset. It reaches its peak 55 degrees above northern horizon at before lowering to 40 degrees above the north western horizon at sunrise. July : visible at its peak, 50 degrees above the northern horizon at sunset. It reaches its peak 55 degrees above northern horizon at before lowering to 25 degrees above the north western horizon at sunrise.
August : visible at its peak, 50 degrees above the northern horizon at sunset. It reaches its peak 55 degrees above northern horizon at The constellation sets at at the northern horizon. September : visible near its peak, 50 degrees above the northern horizon at sunset. Setting at at the northern horizon. October : visible at its peak, 50 degrees above the northern horizon at sunset.
November : visible 40 degrees above the north western horizon at sunset. December : visible briefly after sunset and before sunrise but not visible through most of the night. It appears 30 degrees above the northern horizon at sunset, slightly west of due north. The constellation sets at It appears again above the northern horizon slightly east of due north at It reaches a height of 30 degrees by sunrise.
The average distance to the main stars is The image below was generated using Night Vision , a free to use and download application by Brian Simspon. 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. Thestars mentioned are from the Hipparcos catalogue or have been added because of their special status. The nearest star to Earth is Struve B which is roughly about The nearest star to the Earth with an exoplanet is Edasich which is about The furthest star that is located in the constellation is HIP and it is The furthest figure is derived from either the or Hipparcos star catalogue parallax figure and it has been known to produce distances that are wrong.
The brightest star in Draco is Eltanin and is located about The star has a apparent magnitude of 2. The star is only recognised as being Gamma Draconis rather than having Alpha status. The dimmest star that can be seen in Draco with the naked eye is HIP 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.
