HATS-28 is a white to yellow star that can be located in the constellation of Telescopium. The star can not be seen by the naked eye, you need a telescope to see it. It is calculated at being 6.200 Billion Years old. This information comes from ExoPlanet. HATS-28 has at least 1 Extrasolar Planets believed to be in orbit around the star.
The location of the star in the galaxy 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 HATS-28, the location is 18h 57m 36.00 and -49° 08` 18.50 .
HATS-28 has a spectral type of G. This means the star is a white to yellow star.
HATS-28 has been calculated as 0.92 times bigger than the Sun.The Sun's radius is 695,800km, therefore the star's radius is an estimated 641,527.60.km.
The star's metallicity is 0.060000, 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 6.20 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 1.92 which gives a calculated distance to HATS-28 of 1699.30 light years from the Earth or 521.00 parsecs. It would take a spaceship travelling at the speed of light, 1699.30 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.
