AP Columbae Facts

AP Columbae's Alternative Names

AP Columbae has alternative name(s) :- AP Col.

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

Location of AP Columbae

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 object is compared to the celestial equator and is expressed in degrees. For AP Columbae, the location is 06h 04m 52.1361 and -34° 33` 36.279 .

Radial Velocity and Proper Motion of AP Columbae

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 -91.30 milliarcseconds/year towards the north and -118.90 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 22.40 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 AP Columbae

AP Columbae Colour and Temperature

AP Columbae has a spectral type of M5 D. This means the star is a red star.

Distance to AP Columbae

The Parallax of the star is given as 119.21 which gives a calculated distance to AP Columbae of 27.36 light years from the Earth or 8.39 parsecs. It would take a spaceship travelling at the speed of light, 27.36 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.

The star is roughly 1,730,549.67 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.
