WASP-53 is a orange to red star that can be located in the constellation of Cetus. The description is based on the spectral class. WASP-53 is not part of the constellation but is within the borders of the constellation.

WASP-53 has at least 2 Extrasolar Planets believed to be in orbit around the star.

Location of WASP-53

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 WASP-53, the location is 02h 07m 38.22 and -20° 39` 43.00 .

Physical Properties (Colour, Metallicity, Radius) of WASP-53

WASP-53 has a spectral type of K3. This means the star is a orange to red star.

WASP-53 has been calculated as 0.80 times bigger than the Sun.The Sun's radius is 695,800km, therefore the star's radius is an estimated 555,248.40.km. If you need the diameter of the star, you just need to multiple the radius by 2.

The star's metallicity is 0.110000, 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.

Distance to WASP-53

The Parallax of the star is given as 4.26 which gives a calculated distance to WASP-53 of 766.49 light years from the Earth or 235.00 parsecs. It would take a spaceship travelling at the speed of light, 766.49 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.

The star is roughly 48,471,891.71 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.
