OGLE-2015-BLG-0051 Facts

Location of OGLE-2015-BLG-0051

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 OGLE-2015-BLG-0051, the location is 17h 58m 39.01 and -28° 01` 54.10 .

OGLE-2015-BLG-0051 Colour and Temperature

OGLE-2015-BLG-0051 has a spectral type of G. This means the star is a white to yellow star.

OGLE-2015-BLG-0051 Apparent and Absolute Magnitudes

OGLE-2015-BLG-0051 has an apparent magnitude of 16.40 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 1.83 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 OGLE-2015-BLG-0051

The Parallax of the star is given as 0.12 which gives a calculated distance to OGLE-2015-BLG-0051 of 26734.70 light years from the Earth or 8196.72 parsecs. It would take a spaceship travelling at the speed of light, 26734.70 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.

The star is roughly 1,690,683,081.82 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.
