The Stars in the constellation of Draco
The constellation of Draco is home to several bright stars, including Thuban, the former pole star, and several other stars that make up the dragon’s distinctive shape.
Thuban, also known as Alpha Draconis, is the brightest star in the constellation and was once used as the North Star, serving as a navigational aid for ancient mariners. However, due to the precession of the equinoxes, the North Pole has shifted, and Thuban is no longer the pole star. It is a binary star system with a companion star that orbits around it every 51 days.
Another notable star in Draco is Eltanin, also known as Gamma Draconis. It is the second-brightest star in the constellation and is located near the dragon’s head. Eltanin is also a binary star system, with a companion star that orbits around it every 1,200 years.
Other stars that make up the distinctive shape of Draco include Rastaban, Thuban’s neighbor and Beta Draconis, which is a triple star system. There are also several other stars in the constellation that are visible to the naked eye, making Draco an easy constellation to spot in the night sky.
In addition to these bright stars, Draco is also home to several deep-sky objects, including the Cat’s Eye Nebula, a planetary nebula located in the dragon’s head, and the Draco Dwarf Galaxy, a satellite galaxy of the Milky Way located in the dragon’s tail.
Overall, the stars and deep-sky objects in the constellation of Draco offer a wealth of opportunities for observation and exploration, and are a testament to the beauty and wonder of the night sky.
Deep sky objects visible in the Constellation of Draco
The constellation of Draco is home to several fascinating deep-sky objects that are popular targets for amateur and professional astronomers alike. Here are some of the most notable deep-sky objects visible in Draco:
- Cat’s Eye Nebula: The Cat’s Eye Nebula, also known as NGC 6543, is a planetary nebula located in the dragon’s head. It is a bright and colorful object, with intricate and complex patterns of gas and dust that have been shaped by the dying star at its center.
- NGC 5866: Also known as the Spindle Galaxy, NGC 5866 is a lenticular galaxy located in the tail of Draco. It is notable for its thin, spindle-like shape, which is the result of its orientation relative to our line of sight.
- NGC 5907: The Splinter Galaxy, also known as NGC 5907, is a spiral galaxy located just outside the boundary of Draco. It is a beautiful and intricate galaxy, with a thin, elongated shape and a prominent dust lane that runs through its center.
- Abell 2218: Abell 2218 is a galaxy cluster located in the head of Draco. It is one of the most distant objects visible to amateur astronomers, with a redshift that indicates it is located more than 2 billion light-years away.
- NGC 6543: Also known as the Blue Planetary, NGC 6543 is a planetary nebula located in the head of Draco. It is named for its distinctive blue color, which is caused by ionized oxygen atoms in the nebula.
Overall, the deep-sky objects in Draco offer a fascinating glimpse into the complexity and beauty of the universe. Whether you are a seasoned astronomer or just starting out, observing these objects can be a rewarding and awe-inspiring experience.
