# OO Centaurii

## OO Centaurii Facts

• OO Centaurii's star type is pulsating star that can be located in the constellation of Centaurus. The description is based on the spectral class.
• OO Centaurii is not part of the constellation outline but is within the borders of the constellation.
• The star is calculated at being about 26009.84 light years away from us. Distance

## Location of OO Centaurii

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 OO Centaurii, the location is 13 26 30.0709247164 and -63 09 45.425744560 .

## Radial Velocity and Proper Motion of OO Centaurii

### 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 -1.67 milliarcseconds/year towards the north and -6.71 milliarcseconds/year east if we saw them in the horizon.

The Radial Velocity, that is the speed at which the star is moving away/towards the Sun is -33.00 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.
