OGLE2-TR-L9 Facts

Location of OGLE2-TR-L9

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 object is compared to the celestial equator and is expressed in degrees. For OGLE2-TR-L9, the location is 11h 07m 55.00 and -61° 08` 46.00 .

Physical Properties (Colour, Metallicity, Age, Radius) of OGLE2-TR-L9

OGLE2-TR-L9 Colour and Temperature

OGLE2-TR-L9 has a spectral type of F3. This means the star is a yellow to white star.

OGLE2-TR-L9 Radius

OGLE2-TR-L9 has been calculated as 1.53 times bigger than the Sun. The Sun's radius is 695,800km, therefore the star's radius is an estimated 1,064,574.00.km. If you need the diameter of the star, you just need to multiple the radius by 2.

The star's metallicity is 0.200000, 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 0.66 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.

Distance to OGLE2-TR-L9

The Parallax of the star is given as 1.11 which gives a calculated distance to OGLE2-TR-L9 of 2935.50 light years from the Earth or 900.01 parsecs. It would take a spaceship travelling at the speed of light, 2935.50 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.

The star is roughly 185,639,094.72 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.
