LHS 3844

LHS 3844 is a red star that can be located in the constellation of Indus. The description is based on the spectral class. LHS 3844 is not part of the constellation but is within the borders of the constellation.

LHS 3844 would be an insignificant red dwarf had it not been for the news that N.A.S.A.'s TESS exoplanet hunter spotting an exoplanet in orbit round the star. The planet is one of the first to be discovered and its discovery shared with the wider public along with a second exoplanet orbiting Pi Mensae.

Location of LHS 3844

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 star is compared to the celestial equator and is expressed in degrees. For LHS 3844, the location is 22 41 58.1173365142 and -69 10 08.320922853 .

Proper Motion of LHS 3844

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 -738.00 miliarcseconds/year towards the north and 334.00 miliarcseconds/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 3844

LHS 3844 has a spectral type of M. This means the star is a red star. }

Distance to LHS 3844

The Parallax of the star is given as 67.15 which gives a calculated distance to LHS 3844 of 48.57 light years from the Earth or 14.89 parsecs. It would take a spaceship travelling at the speed of light, 48.57 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.

The star is roughly 3,071,261.56 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.
