WASP-140

WASP-140 is a orange to red star that can be located in the constellation of Eridanus. The description is based on the spectral class. WASP-140 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 1.600 Billion Years old. This information comes from ExoPlanet. WASP-140 has at least 1 Extrasolar Planets believed to be in orbit around the star.

Location of WASP-140

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-140, the location is 04h 01m 33.00 and -20° 27` 04.00 .

Physical Properties (Colour, Metallicity, Age, Radius) of WASP-140

WASP-140 has a spectral type of K0. This means the star is a orange to red star.

WASP-140 has been calculated as 0.87 times bigger than the Sun.The Sun's radius is 695,800km, therefore the star's radius is an estimated 605,346.00.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.

The star is believed to be about 1.60 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-140 Apparent and Absolute Magnitudes

WASP-140 has an apparent magnitude of 11.10 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 4.82 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-140

The Parallax of the star is given as 5.56 which gives a calculated distance to WASP-140 of 587.09 light years from the Earth or 180.00 parsecs. It would take a spaceship travelling at the speed of light, 587.09 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.

The star is roughly 37,127,406.42 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.
