Facts
Kepler 1638star is located in the constellation of Cygnus, The Swan . It is not part of the Cygnus constellation outline but is within the borders of the constellation.
Based on a parallax of 1.1377, Kepler 1638 distance from Earth can be calculated at being 2,866.87 light years away or 878.97 parsecs.
Exoplanet(s)
There is 1 exoplanet that has been discovered or is speculated (inc. candidates, controversial, retracted & others) to exist orbiting this star.
Location
The location of the Kepler 1638 in the night sky is determined by the right ascension (R.A.) and declination (Dec.). These are equivalent to the Longitude and Latitude on Earth. The Right Ascension (Longitude) is expressed in time (hh:mm:ss) and is how far the star is along Earth's celestial equator. If the R.A. is positive, then it's eastwards and vice versa.
The Declination (Latitude) is how far north or south the object is compared to the celestial equator and is expressed in degrees. If the value is positive, it is north of the celestial equator. For Kepler 1638, the location is 19h 41m 55.78 and 48° 31` 28.00 .
Based on the location of Cygnus, Kepler 1638 can be located in the northern hemisphere of the celestial sky. The celestial hemisphere is equivalent to the hemispheres on Earth. Kepler 1638 is north of the Ecliptic. The Ecliptic is the path that the Earth takes as it orbits the Sun. As the Earth is titled, we therefore have Celestial and Ecliptic hemispheres and they can be different for a star.
Physical Properties
Spectral Type
There is no relationship between colour and size. For example, a red star can be large or small. Small stars are more energy efficient than larger stars and live longer.
Kepler 1638 Size (Radius)
Kepler 1638 radius has been calculated as being 0.95 times bigger than the Sun. The Sun's radius is 695,800km, therefore, the Kepler 1638 radius is an estimated 661,010.km. If you need the star's diameter, you just need to multiply the radius by 2.
Kepler 1638 Metallicity
Kepler 1638 metallicity is 0.188000, 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.
