OGLE-2005-390L Facts

Information on OGLE-2005-390L


As part of the 2019 Star Wars Day celeberations N.A.S.A released a press release stating which exoplanets it felt was closest to the planets in the Star Wars films. They had decided that the exoplanet here most resembled Hoth, the ice world which the Rebel Alliance sought safety after destroying the Death Star at the end of the previous film.

The planet Hoth had Taun-Tauns and Wampas but considering the planet is a freezing -220 Celsius, nothing life forms could possibly survive on that planet.

The planet had been discovered using micro-lensing, light from a distant object is magnified by a closer object. Micro-lensing is just one technique which scientists use to discover objects farther away. Other techniques include Transit and Radial Velocity.

Location of OGLE-2005-390L

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-2005-390L, the location is 17h 54m 19.00 and -30° 22` 38.00 .

OGLE-2005-390L has a spectral type of M. This means the star is a red star.

Distance to OGLE-2005-390L

The Parallax of the star is given as 0.15 which gives a calculated distance to OGLE-2005-390L of 21206.98 light years from the Earth or 6501.95 parsecs. It would take a spaceship travelling at the speed of light, 21206.98 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.

The star is roughly 1,341,114,111.97 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.
