Am Canum Venaticorum

Am Canum Venaticorum Facts

Information on Am Canum Venaticorum

The AM CVn star is believed to be consisting of two binary white dwarfs that are in close proximity to one another. The stars contain no hydrogen, having used up the hydrogen, leaving only helium. It is believed that they are a source of gravitational waves that were picked up Lisa. David Darling.

Location of Am Canum Venaticorum

The location of the dwarf 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 Am Canum Venaticorum, the location is 12 34 54.6230046722 and +37 44.120772480 .

Proper Motion of Am Canum Venaticorum

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 12.42 milliarcseconds/year towards the north and 30.94 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 Am Canum Venaticorum

Am Canum Venaticorum Colour and Temperature

Am Canum Venaticorum has a spectral type of DBnnp D. This means the star is a white dwarf star.

Distance to Am Canum Venaticorum

The Parallax of the star is given as 3.35 which gives a calculated distance to Am Canum Venaticorum of 973.27 light years from the Earth or 298.40 parsecs. It would take a spaceship travelling at the speed of light, 973.27 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.

The star is roughly 61,548,989.30 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.
