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 220621087, the location is 01h 17m 13.09 and 09° 30` 04.97 .
Based on the star's spectral type of M1.5V , EPIC 220621087's colour and type is red main sequence star. Based on the star's spectral, the stars temperature is between 2,400.00 and 3,700.00 degrees kelvin.
EPIC 220621087 Radius has been calculated as being 0.43 times bigger than the Sun. The Sun's radius is 695,800km, therefore the star's radius is an estimated 298,498.20.km. If you need the diameter of the star, you just need to multiple the radius by 2.
The star's metallicity is 0.120000, 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.
The Parallax of the star is given as 15.94900 which gives a calculated distance to EPIC 220621087 of 204.50 light years from the Earth or 62.70 parsecs. It is about 1,202,178,888,816,048 miles from Earth.
The star is roughly 12,932,713.24 Astronomical Units from the Earth/Sun give or take a few. An Astronomical Unit is the distance between Earth and the Sun. The number of A.U. is the number of times that the star is from the Earth compared to the Sun.
The time it will take to travel to this star is dependent on how fast you are going. U.G. has done some calculations as to how long it will take going at differing speeds. A note about the calculations, when I'm talking about years, I'm talking non-leap years only (365 days).
The New Horizons space probe is the fastest probe that we've sent into space at the time of writing. Its primary mission was to visit Pluto which at the time of launch (2006), Pluto was still a planet.
