WASP-100

Primary Facts on WASP-100

  • WASP-100's star type is star that can be located in the constellation of Reticulum. The description is based on the spectral class.
  • WASP-100 is not part of the constellation outline but is within the borders of the constellation.
  • Based on the spectral type (F2) of the star, the star's colour is blue to white .
  • The star can not be seen by the naked eye, you need a telescope to see it.
  • WASP-100 has at least 1 Extrasolar Planets believed to be in orbit around the star.

Location of WASP-100

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-100, the location is 04h 35m 49.99 and -64° 01` 36.84 .

Physical Properties (Colour, Metallicity, Radius) of WASP-100

WASP-100 has a spectral type of F2. This means the star is a blue to white star.

WASP-100 has been calculated as 2.00 times bigger than the Sun.The Sun's radius is 695,800km, therefore the star's radius is an estimated 1,391,600.00.km. If you need the diameter of the star, you just need to multiple the radius by 2.

The star's metallicity is 0.100000, 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.

WASP-100 Apparent and Absolute Magnitudes

WASP-100 has an apparent magnitude of 10.80 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. 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.
