Gliese 570 D (Companion Star) Facts

Gliese 570 D Facts

  • Gliese 570 D is a cool methane dwarf Star that can be located in the constellation of Libra. The description is based on the spectral class.
  • Gliese 570 D is not part of the constellation outline but is within the borders of the constellation.
  • Based on the spectral type (T8 C) of the star, the star's colour is brown.
  • The star is calculated at being about 19.27 light years away from us. Distance

Location of Gliese 570 D

The location of the cool methane dwarf 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 Gliese 570 D, the location is 14h 57m 14.96 and -21° 21` 47.8 .

Proper Motion of Gliese 570 D

All stars like planets orbit round a central spot, in the case of planets, its the central star such as the Sun. In the case of a star, its the galactic centre. The constellations that we see today will be different than they were 50,000 years ago or 50,000 years from now. Proper Motion details the movements of these stars and are measured in milliarcseconds. The star is moving -1,726.00 milliarcseconds/year towards the north and 1,034.00 milliarcseconds/year east if we saw them in the horizon. . When the value is negative then the star and the Sun are getting closer to one another, likewise, a positive number means that two stars are moving away. Its nothing to fear as the stars are so far apart, they won't collide in our life-time, if ever.

Physical Properties of Gliese 570 D

Gliese 570 D Temperature and Colour

Based on the star's spectral type of T8 C , Gliese 570 D's colour and type is brown cool methane dwarf Star. Based on the star's spectral, the stars temperature is between 0.00 and 0.00 degrees kelvin.

Distance to Gliese 570 D

The Parallax of the star is given as 169.30000 which gives a calculated distance to Gliese 570 D of 19.27 light years from the Earth or 5.91 parsecs. It is about 113,281,110,941,248 miles from Earth.

The star is roughly 1,219,016.51 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.

Travel Time to Gliese 570 D

The time it will take to travel to this star is dependent on how fast you are going. U.G. has done some calculations as to how long it will take going at differing speeds. A note about the calculations, when I'm talking about years, I'm talking non-leap years only (365 days).

The New Horizons space probe is the fastest probe that we've sent into space at the time of writing. Its primary mission was to visit Pluto which at the time of launch (2006), Pluto was still a planet.
