KY Cygni is a red very luminous supergiant star that can be located in the constellation of Cygnus. KY Cygni has alternative name(s), KY Cyg , .
The location of the star in the galaxy 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 38d 21' 7.6 .
Luminosity is the amount of energy that a star pumps out and its relative to the amount that our star, the Sun gives out. The figure of 54000.0000000 that I have given is based on the Spectral Types page that I have found on the Internet. You might find a different figure, one that may have been calculated rather than generalised that I have done. The figure is always the amount times the luminosity of the Sun. It is an imprecise figure because of a number of factors including but not limited to whether the star is a variable star and distance.
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.
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.
