KY Cygni is a red supergiant star that can be located in the constellation of Cygnus. The description is based on the spectral class. The star can not be seen by the naked eye, you need a telescope to see it.
KY Cygni has alternative name(s) :- KY Cyg .
More details on star alternative names can be found at Star Names .
The location of the star in the night sky is determined by the Right Ascension (R.A.) and Declination (Dec.), these are equivalent to the Longitude and Latitude on the Earth. The Right Ascension is how far expressed in time (hh:mm:ss) the star is along the celestial equator. If the R.A. is positive then its eastwards. The Declination is how far north or south the star is compared to the celestial equator and is expressed in degrees. For KY Cygni, the location is 20h 25m 58.05 and 38° 21` 7.6 .
KY Cygni has a spectral type of M3-4I. This means the star is a red supergiant star. KY Cygni lies at a distance of 5,000.00 light years away from our Sun and our planet Earth or to put it another way, 1,532.97 parsecs away from the Sun.
KY Cygni has been calculated as 1,420.00 times bigger than the Sun.The Sun's radius is 695,800km, therefore the star's radius is an estimated 988,036,000.00.km. If you need the diameter of the star, you just need to multiple the radius by 2.
KY Cygni has an apparent magnitude of 11.14 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. Magnitude, whether it be apparent/visual or absolute magnitude is measured by a number, the smaller the number, the brighter the Star is. Our own Sun is the brightest star and therefore has the lowest of all magnitudes, -26.74. A faint star will have a high number.
KY Cygni is an estimated 5,000.00 light years from our Solar System (Earth and Sun). It would take a spaceship 5,000.00 years travelling at the speed of light to get there. We don't have a space ship that can travel that distance or at that speed yet.
