V346 Centauri Facts

V346 Centauri's Alternative Names

The Id of the star in the Henry Draper catalogue is HD101837.

V346 Centauri has alternative name(s) :- V346 Cen.

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

Location of V346 Centauri

The location of the giant 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 V346 Centauri, the location is 11 42 49.6741357418 and -62 26 05.401518409 .

Radial Velocity and Proper Motion of V346 Centauri

Proper Motion

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 0.74 milliarcseconds/year towards the north and -6.17 milliarcseconds/year east if we saw them in the horizon.

Radial Velocity

The Radial Velocity, that is the speed at which the star is moving away/towards the Sun is -6.40 km/s . 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 V346 Centauri

V346 Centauri Colour and Temperature

V346 Centauri has a spectral type of B1/3II/III E. This means the star is a blue giant star.

Distance to V346 Centauri

The Parallax of the star is given as 0.40 which gives a calculated distance to V346 Centauri of 8154.08 light years from the Earth or 2500 parsecs. It would take a spaceship travelling at the speed of light, 8154.08 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.

The star is roughly 515,658,422.46 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.
