HATS-28

Primary Facts on HATS-28

Location of HATS-28

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 object 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 .

Physical Properties (Colour, Metallicity, Age, Radius) of HATS-28

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. If you need the diameter of the star, you just need to multiple the radius by 2.

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.

Distance to HATS-28

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.

The star is roughly 107,463,215.24 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.
