LHS 1989 (High Proper Motion Star) Facts

LHS 1989 Facts

Location of LHS 1989

The location of the main sequence 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 LHS 1989, the location is 08 12 40.8887006440 and -21 33 06.982376130 .

Proper Motion of LHS 1989

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 -694.02 milliarcseconds/year towards the north and 13.70 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 (Colour) of LHS 1989

LHS 1989 Colour and Temperature

LHS 1989 has a spectral type of M3.5V C. This means the star is a red main sequence star.

Distance to LHS 1989

The Parallax of the star is given as 123.22 which gives a calculated distance to LHS 1989 of 26.47 light years from the Earth or 8.12 parsecs. It would take a spaceship travelling at the speed of light, 26.47 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.

The star is roughly 1,674,858.56 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.
