HATS-25 Facts

  • HATS-25 is a star that can be located in the constellation of Hydra. The description is based on the spectral class.
  • HATS-25 is not part of the constellation outline but is within the borders of the constellation.
  • Based on the spectral type (G) of the star, the star's colour is yellow .
  • The star can not be seen by the naked eye, you need a telescope to see it.
  • It is calculated at being 7.500 Billion Years old. This information comes from ExoPlanet.
  • HATS-25 has at least 1 Extrasolar Planets believed to be in orbit around the star.
  • HATS-25 has a radius that is 1.11 times bigger than the Suns. Radius
  • The star is calculated at being about 1519.94 light years away from us. Distance

Location of HATS-25

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-25, the location is 13h 51m 37.80 and -23° 46` 52.20 .

Physical Properties of HATS-25

HATS-25 Colour and Temperature

Based on the star's spectral type of G , HATS-25's colour and type is yellow star. Based on the star's spectral, the stars temperature is between 5,200.00 and 6,000.00 degrees kelvin.

HATS-25 Radius

HATS-25 Radius has been calculated as being 1.11 times bigger than the Sun. The Sun's radius is 695,800km, therefore the star's radius is an estimated 770,250.60.km. If you need the diameter of the star, you just need to multiple the radius by 2.

HATS-25 Metalicity

The star's metallicity is 0.050000, 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.

HATS-25 Estimated Age

The star is believed to be about 7.50 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.

HATS-25 Apparent and Absolute Magnitudes

HATS-25 has an apparent magnitude of 13.10 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. Using the supplied Parallax value, you would get an absolute magnitude of 4.76 Magnitude, whether it be apparent/visual or absolute magnitude is measured by a number, the smaller the number, the brighter the Star is. Our own Sun is the brightest star and therefore has the lowest of all magnitudes, -26.74. A faint star will have a high number.

Distance to HATS-25

The Parallax of the star is given as 2.14590 which gives a calculated distance to HATS-25 of 1519.94 light years from the Earth or 466.00 parsecs. It is about 8,935,157,849,716,696 miles from Earth.

The star is roughly 96,118,729.95 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.

Travel Time to HATS-25

The time it will take to travel to this star is dependent on how fast you are going. U.G. has done some calculations as to how long it will take going at differing speeds. A note about the calculations, when I'm talking about years, I'm talking non-leap years only (365 days).

The New Horizons space probe is the fastest probe that we've sent into space at the time of writing. Its primary mission was to visit Pluto which at the time of launch (2006), Pluto was still a planet.
