In March DMS Corporation traditionally celebrates its birthday. Donetsk holding successful existence on the market for over 12 years has inspired long-time friends and partners to make an unusual gift. One of the stars in the constellation Big Dipper, now bears the official name of DMS. It is a symbolic gift: like stars form a map of the sky, the companies - large and small - form a “map” of the domestic economy.
The star from the catalog SPACE-EARTH, previously registered under the number 03060211728, today is called DMS. It is located in the constellation Big Dipper at a distance of 40 time minutes from the well-known variable star called 29UMA (UPSυ). According to the spectral class the star is close to the α Bootes stars (Arcturus, β Gemini (Pollux), α Tauri (Aldebaran) and has the following equatorial coordinates: right ascension (j2000) - 09h 09m 49,7 s, declination (j2000): - +59 ° 09'14 , 3".
Recall that International star catalogue “Kosmos-Zemlya” ISC «SPACE-EARTH» was founded on the basis of space research by the Soviet satellites. In 1993 the data was obtained on the location of several millions of celestial objects with the aim of cataloging them. This work was completed in 2 years and the electronic catalogue with information on 6.5 million stars to 15th magnitude inclusive was created. In 2005 it was decided to protect the original version of the catalogue and to have the annual certification and registration of official resources of the international star catalogue SPACE-EARTH.
The age of DMS Star is billions of years, the spectral class - K2, the distance to the star is 216.0 light years, 13,650,893.4 astronomical years, 66.2 parsecs 204.1 * 10 ¹ ³ km. Visual magnitude - m = 6,4, the absolute magnitude - M = 3,0. Mass of the star is ≈ 1,5 of solar masses, the stellar radius is approximately equal to 3.8 solar radius, luminosity ≈ 5,2 solar luminosity, effective surface temperature - ≈ 4600 ° Kelvin.
DMS star brightness varies from Vmax = 6,2 to Vmin = 6,8.
Big Dipper is a large northern constellation whose area is 1279.7 square degrees and it includes 210 stars visible to the naked eye.
