WASP-133

WASP-133 is a white to yellow star that can be located in the constellation of Microscopium. 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 6.800 Billion Years old. This information comes from ExoPlanet. WASP-133 has at least 1 Extrasolar Planets believed to be in orbit around the star.

Location of WASP-133

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-133, the location is 20h 58m 18.00 and -35° 47` 48.00 .

Physical Properties (Colour, Metallicity, Age, Radius) of WASP-133

WASP-133 has a spectral type of G4. This means the star is a white to yellow star.

WASP-133 has been calculated as 1.44 times bigger than the Sun.The Sun's radius is 695,800km, therefore the star's radius is an estimated 1,001,952.00.km. If you need the diameter of the star, you just need to multiple the radius by 2.

The star's metallicity is 0.120000, 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 6.80 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-133 Apparent and Absolute Magnitudes

WASP-133 has an apparent magnitude of 12.90 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 4.60 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-133

The Parallax of the star is given as 2.19 which gives a calculated distance to WASP-133 of 1490.56 light years from the Earth or 457.00 parsecs. It would take a spaceship travelling at the speed of light, 1490.56 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.
