The location of the main sequence 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 object is compared to the celestial equator and is expressed in degrees. For EPIC 204221263, the location is 16h 00m 08.00 and -23° 11` 21.00 .
EPIC 204221263 has a spectral type of G2V. This means the star is a white to yellow main sequence star.
EPIC 204221263 has been calculated as 1.10 times bigger than the Sun. The Sun's radius is 695,800km, therefore the star's radius is an estimated 765,380.00.km. If you need the diameter of the star, you just need to multiple the radius by 2.
The star's metallicity is 0.040000, this value is the fractional amount of the star that is not Hydrogen (X) or Helium (Y). An older star would have a high metallicity whereas a new star would have a lower one.
EPIC 204221263 has an apparent magnitude of 11.39 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.
