WASP-84 is a orange to red star that can be located in the constellation of Hydra. The description is based on the spectral class. It is calculated at being 1.000 Billion Years old. This information comes from ExoPlanet. WASP-84 has at least 1 Extrasolar Planets believed to be in orbit around the star.
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-84, the location is 08h 44m 25.99 and 01° 50` 35.88 .
WASP-84 has a spectral type of K0. This means the star is a orange to red star.
WASP-84 has been calculated as 0.75 times bigger than the Sun.The Sun's radius is 695,800km, therefore the star's radius is an estimated 520,458.40.km. If you need the diameter of the star, you just need to multiple the radius by 2.
The star's metallicity is 0.100000, 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 star is believed to be about 1.00 Billion years old. To put in context, the Sun is believed to be about five billion years old and the Universe is about 13.8 billion years old.
The Parallax of the star is given as 8.33 which gives a calculated distance to WASP-84 of 391.40 light years from the Earth or 120.00 parsecs. It would take a spaceship travelling at the speed of light, 391.40 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.
