WASP-46 is a white to yellow main sequence dwarf star that can be located in the constellation of Indus. The description is based on the spectral class. WASP-46 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. It is calculated at being 1.400 Billion Years old. This information comes from ExoPlanet. WASP-46 has at least 1 Extrasolar Planets believed to be in orbit around the star.
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-46, the location is 21h 14m 57.00 and -55° 52` 18.00 .
WASP-46 has a spectral type of G6V. This means the star is a white to yellow main sequence dwarf star.
WASP-46 has been calculated as 0.92 times bigger than the Sun.The Sun's radius is 695,800km, therefore the star's radius is an estimated 638,048.60.km. If you need the diameter of the star, you just need to multiple the radius by 2.
The star's metallicity is 0.130000, 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 1.40 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-46 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. 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. }
