8/16/2023 0 Comments Little dipper constellation![]() ![]() Unlike its Big Dipper counterpart, the Little Dipper does not have many nearly deep-sky objects. The Big and Little Dipper are arranged with their handles pointing in opposite directions, meaning one Dipper is upright while the other is upside down. Simply locate the outer two stars in the Big Dipper bowl (Merak and Dubhe) and draw an imaginary line through both stars, extended outwards until you locate a bright star-forming the end of the Little Dipper handle. While you might not be able to see the Little Dipper, you can use the stars from the Big Dipper to locate Polaris. This would explain why you might not be able to locate the Little Dipper. With the stars in the bowl being so dim, you will need a darker sky in order to see them. Light pollution in the form of sky glow from urban city centers and surrounding suburbs affects the overall darkness of the sky. Polaris nearly in line with the North Celestial Pole. However, since the stars in the Little Dipper range in brightness from second to fifth magnitude, it may be difficult to see depending on the quality of your night sky. The Little Dipper is visible between latitudes 90 and -10 with the best time to observe in the month of June. It is approximately 131 light-years from Earth and is known as the other ‘guardian of the poke star’ along with Pherkad. Kochab forms the lower outer bowl and is an orange giant star only slightly fainter than Polaris at an apparent magnitude of 2.08. It is also known, along with Kochab, as the ‘guardians of the pole star’. Pherkad, forming the top end of the bowl, is a white bright giant with an apparent magnitude that varies between 3.04 and 3.09. This star is 97 light-years away from Earth. Eta Ursae MinorisĮta is a main sequence dwarf with a visual magnitude of 4.95, making it the dimmest of the seven stars. ![]() It is approximately 380 light-years away from Earth. Zeta is a white main-sequence star of spectral type F5V with a visual magnitude of 4.32. Epsilon is approximately 347 light-years away. The system includes a yellow G-type giant, which is also an eclipsing spectroscopic binary star and is orbited by an 11th magnitude star. Epsilon Ursae MinorisĮpsilon is a triple star system with an overall brightness that varies from 4.19 to 4.23 in magnitude. It is of the spectral type A1V, is 47 times more luminous than the Sun and approximately 175 light-years from Earth. Polaris is a triple star system that includes Polaris Aa and its dimmer counterparts, Polaris Ab and Polaris B which are approximately 434 light-years away.ĭue to its close proximity to the rotational axis of Earth, the star appears motionless in the sky which makes it an important star in celestial navigation.ĭelta is a white main sequence dwarf star with a visual magnitude of 4.35. It is a yellow-white supergiant with an apparent magnitude of 2.02 and a varying spectral type of F7lb/F8lb. Polaris, or Pole Star, is the end of the handle (or Bear’s tail) and is the brightest star in the Ursa Minor constellation. John Chumack The Handle Alpha Ursae Minoris (Polaris) Names of the stars in Little Dipper and their approximate magnitude. There are seven stars that make up the Little Dipper, they include: ![]() The stars in the Little Dipper were named after a cartographer who used Greek letters alpha to label the most prominent stars in the constellation. For this reason, Polaris is a known navigational tool. the North Star or Pole Star) which is located almost directly above the North Celestial Pole and marks the direction of due north. The Little Dipper is an asterism and is not considered a formal constellation. Similar to the Big Dipper, the handle forms the tail of the little bear, while the bowl forms the bear’s flake/hindquarters. The Little Dipper is a pattern of stars found in the Ursa Minor constellation (i.e. ![]()
