WASP-104 is a white to yellow star that can be located in the constellation of Leo. The description is based on the spectral class. WASP-104 is not part of the constellation but is within the borders of the constellation.

The star can not be seen by the naked eye, you need a telescope to see it. WASP-104 has at least 1 Extrasolar Planets believed to be in orbit around the star.

Location of WASP-104

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-104, the location is 10h 42m 24.61 and 07° 26` 06.30 .

Physical Properties (Colour, Metallicity, Radius) of WASP-104

WASP-104 has a spectral type of G8. This means the star is a white to yellow star.

WASP-104 has been calculated as 0.93 times bigger than the Sun.The Sun's radius is 695,800km, therefore the star's radius is an estimated 647,094.00.km. If you need the diameter of the star, you just need to multiple the radius by 2.

The star's metallicity is 0.090000, 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-104 Apparent and Absolute Magnitudes

WASP-104 has an apparent magnitude of 11.12 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 5.34 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-104

The Parallax of the star is given as 6.99 which gives a calculated distance to WASP-104 of 466.41 light years from the Earth or 143.00 parsecs. It would take a spaceship travelling at the speed of light, 466.41 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.

The star is roughly 29,495,661.76 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.
