HIP 64634

Primary Facts on HIP 64634

  • HIP 64634's star type is star that can be located in the constellation of Coma Berenices. The description is based on the spectral class.
  • HIP 64634 is not part of the constellation outline but is within the borders of the constellation.
  • The star can not be seen by the naked eye, you need a telescope to see it.
  • Using the most recent figures given by the 2007 Hipparcos data, the star is 378.82 light years away from us.

HIP 64634's Alternative Names

HIP64634 is the reference name for the star in the Hipparcos Star Catalogue.

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

Location of HIP 64634

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 star is compared to the celestial equator and is expressed in degrees. For HIP 64634, the location is 13h 14m 52.98 and +29° 44` 56.7 .

Radial Velocity and Proper Motion of HIP 64634

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 -40.20 ± 1.54 miliarcseconds/year towards the north and 74.02 ± 2.41 miliarcseconds/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 8.00 km/s with an error of about 0.70 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.

Source of Information

The source of the information if it has a Hip I.D. is from Simbad, the Hipparcos data library based at the University at Strasbourg, France. Hipparcos was a E.S.A. satellite operation launched in 1989 for four years. The items in red are values that I've calculated so they could well be wrong. Information regarding Metallicity and/or Mass is from the E.U. Exoplanets. The information was obtained as of 12th Feb 2017.
