Constellation Indians

Constellations > Indian

The Indian is a constellation that is located in the southern hemisphere and does not have bright stars.

The constellation depicts an Indian, hinting at an inhabitant of Asia or America. It was created by Peter Plancius at the end of the 16th century. First appeared in “Uranometrics” (1603) by Johann Bayer. Plancius portrayed him as a naked man holding arrows in his hands. This is a faint constellation. The brightest stars do not exceed magnitude 3. But there are several known galaxies: NGC 7049, NGC 7064, NGC 7083, NGC 7090 and IC 5152.

Facts, position and map

With an area of ​​294 square degrees, the Indian constellation is the 49th largest constellation. Covers the fourth quadrant in the southern hemisphere (SQ4). Can be found at latitudes between + 15 ° and -90 °. Neighbors with Microscope, Octant, Peacock, Telescope, Toucan, Sagittarius and Crane.

Accommodates two stars with planets and no Messier objects or meteor shower. The brightest star is Alpha Indian, whose apparent visual magnitude reaches 3.11. It is part of the Bayer group, where you can also find Chameleon, Goldfish, Fly, Peacock, Phoenix, Toucan, Flying Fish, Southern Hydra, Crane and Bird of Paradise.

History

The constellation is not associated with any myth. Usually this is an Indian, prowling with arrows and spears, as if on a hunt. Early images (including Uranometria) show that this character may have been from Madagascar, hinting at the first voyage of Dutch sailors to the East Indies. But there is no exact information about this. The fact is that sailors have traveled to different countries and encountered many indigenous peoples, so it is almost impossible to determine a specific place and a native.

Main stars

Explore the bright stars of the constellation Indus in the southern hemisphere with detailed descriptions and characteristics.

Alpha Indian is a star of spectral type K0 III-IV (evolved from the main sequence and passed into the giant stage). With an apparent visual magnitude of 3.11, it is located 98.3 light years from our system. It is sometimes called the Persian star. It has a pair of red dwarfs with magnitudes 12 and 13. It is 2 times the solar mass and 12 times more in radius. Age is a billion years.

Beta Indian is a bright giant (K1II), whose visual magnitude reaches 3.658, and is 600 light years distant. It is accompanied by a visual companion with an apparent magnitude of 12.5.

Epsilon Indian is a main sequence star, a dwarf (K5V), located 11.83 light years away. The star has two satellites – brown dwarfs (T1V and T6V), found in 2003. In the images, the star symbolizes one of the arrows, which the Indian holds in his left hand.

It takes the third place in the speed of its own motion among the stars visible to the naked eye, and the ninth among the total number. It is expected to move to the constellation Toucan in 2640.

Theta Indian is a double star, 91 light years distant. It is represented by stars with magnitude 5 and 7, which are easy to find with a small telescope.

Rho Indian is a yellow subgiant (G2.5IV) with an apparent visual magnitude of 6.064 and a distance of 86.43 light years. The age is 13 billion years. Soon it will end its existence in the form of a planetary nebula. In 2002, planet Rho, Indian b, was spotted in orbit.

T Indian is a semi-regular variable star with fluctuations in magnitude 7-5. It is a red giant with a period of 11 months, distant from us by 1900 light years.

Celestial objects

NGC 7049 is a galaxy located 100 million light years from our planet. It spans approximately 150,000 light years in size. A noticeable dust ring and a relatively small cluster of stars are striking. Has the characteristics of spiral and elliptical galaxies. She looks unusual. Several recent collisions with other galaxies are believed to be responsible for this. A star is visible at the top of the ring, which is actually located in the Milky Way.

IC 5152 is an irregular galaxy found in 1908 by American astronomer Delil Stewart. There is no evidence yet as to whether she is a distant member of the Local Group of Galaxies.

Objects are quickly located within its limits, but a very bright star in the foreground makes deep observations difficult.

NGC 7090 is a spiral galaxy with an apparent magnitude of 10.51 and a distance of 30 million light years. On October 4, 1834, John Herschel found her.

NGC 7083 is a barred spiral galaxy of magnitude 12. It is considered a grand design type spiral galaxy. In 2009, a supernova SN 2009hm was observed.

NGC 7041 is an elliptical galaxy with a visual magnitude of 11.1. It was discovered by John Herschel on July 7, 1834.

NGC 7064 is a barred spiral galaxy discovered on July 8, 1834 by John Herschel. Apparent magnitude – 12.2.

NGC 7029 is a bright elliptical galaxy with an apparent visual magnitude of 11.7 and a distance of 36.3 Mpc (118.4 million light years). John Herschel discovered it in 1834.

NGC 7140 is a spiral galaxy discovered in October 1834 by John Herschel observing from the Cape of Good Hope. It is 37.4 Mpc (122 million light years) distant and has a visual magnitude of 11.7.

You have the opportunity to study the constellation Indian of the southern hemisphere more closely if you use not only our photos, but 3D models and an online telescope. For an independent search, a map of the starry sky is suitable.
