Where is ursa minor in the sky
It has been responsible for showing us true north and helping people of the sea for centuries. Do you know which star we are talking about? The Ursa Minor constellation is usually associated with two different myths. In the first story, Ursa Minor is a representation of Ida, a nymph who cared for Zeus when he was born. He was doing this because a prophet told him his son would overthrow him.
The other myth associated with Ursa Minor is a tale of lovers, betrayal and envy. Then, depending on which myth you continue to follow, Zeus placed Arcas and the bear into the sky to stop them fighting each other, or to protect them from hunters and people wanting to capture them. If we join the dots of a constellation together in a specific way, we get an outline of a shape which can then be interpreted to resemble an image.
Most of the time Ursa Minor is said to resemble a small bear. This continues the symbolism of Ursa Major, which also resembles a bear of the sky, albeit much larger. The constellation is surrounded by the Draco constellation, which depicts a dragon that surrounds the little bear.
These are the images our ancient ancestors saw in the sky and connected them with myths. But we have to be prepared to use our imagination to some extent to see what they once saw.

Polaris mag 2. IC mag NGC mag Kochab mag 2. Polaris , the closest bright star to the north celestial pole since the High Middle Ages, is the brightest star in Ursa Minor. It has an apparent magnitude of 1. The star is approximately light years distant from Earth.
The easiest way to find Polaris in the night sky is to follow Dubhe and Merak , the two bright stars at the end of the Big Dipper asterism in Ursa Major , upwards and then look for the nearest bright star. Bacon STScI. It has a mass six times that of the Sun. Polaris is classified as a Population I Cepheid variable. When Ptolemy observed Polaris , it was a third magnitude star, but today it is 2.
It has a visual magnitude of 2. It is the brightest star in the bowl of the Little Dipper. Kochab and Pherkad, Gamma Ursae Minoris, are sometimes called the Guardians of the Pole because they appear to be rotating around Polaris. From BC to AD, the two stars served as twin pole stars, being the closest bright stars to the north celestial pole. Neither of the two, however, was as close to the pole as Polaris currently is.
Pherkad, Gamma Ursae Minoris, is an A-type star with an apparent magnitude of 3. It has the stellar classification A3 lab, which means that it is an intermediate luminosity supergiant. It is a very fast rotating star, with a rotational velocity estimated at kilometres per second.
Its radius is 15 times solar and it is 1, times more luminous than the Sun. Delta Ursae Minoris is a white main sequence dwarf of the spectral type A1V, approximately light years from Earth.
It has a visual magnitude of 4. The name is sometimes also spelled Vildiur, Jildun, Yilduz and Gildun. Zeta Ursae Minoris is a main sequence dwarf belonging to the spectral type A3Vn.
