WASP-108

WASP-108 is a blue to white star that can be located in the constellation of Centaurus. The description is based on the spectral class. The star can not be seen by the naked eye, you need a telescope to see it. It is calculated at being 4.600 Billion Years old. This information comes from ExoPlanet. WASP-108 has at least 1 Extrasolar Planets believed to be in orbit around the star.

Location of WASP-108

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-108, the location is 13h 03m 19.00 and -49° 38` 23.00 .

Physical Properties (Colour, Metallicity, Age, Radius) of WASP-108

WASP-108 has a spectral type of F9. This means the star is a blue to white star.

WASP-108 has been calculated as 1.22 times bigger than the Sun.The Sun's radius is 695,800km, therefore the star's radius is an estimated 845,397.00.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.

The star is believed to be about 4.60 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.

WASP-108 Apparent and Absolute Magnitudes

WASP-108 has an apparent magnitude of 11.20 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 4.49 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 WASP-108

The Parallax of the star is given as 4.55 which gives a calculated distance to WASP-108 of 717.55 light years from the Earth or 220.00 parsecs. It would take a spaceship travelling at the speed of light, 717.55 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.
