More details on objects' alternative names can be found at Star Names .

Location of HD 140585

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 HD 140585, the location is 15h 47m 29.124 and -59° 10` 40.106 .

Proper Motion of HD 140585

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 -7.68 milliarcseconds/year towards the north and -10.39 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 HD 140585

HD 140585 Colour and Temperature

HD 140585 has a spectral type of F2 V. This means the star is a yellow to white main sequence star.

Distance to HD 140585

The Parallax of the star is given as 8.44 which gives a calculated distance to HD 140585 of 386.44 light years from the Earth or 118.48 parsecs. It would take a spaceship travelling at the speed of light, 386.44 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.

The star is roughly 24,438,083.96 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.
