56 Virginis, HD115062, HIP64625

56 Virginis is a orange to red star that can be located in the constellation of Virgo. The star can not be seen by the naked eye, you need a telescope to see it.

56 Virginis's Alternative Names

HIP64625 is the reference name for the star in the Hipparcos Star Catalogue. The Id of the star in the Henry Draper catalogue is HD115062.

Flamsteed designations are named after the creator, Sir John Flamsteed. Sir John numbered the stars in the constellation with a number and the latin name, this star's Flamsteed designation is 56 Virginis with it shortened to 56 Vir.

The Gould star designation is one that was designed by American astronomer, Benjamin Apthorp Gould. Gould stars are predominantly in the Southern and Equatorial constellations but do appear in northern constellations such as Bootes and Orion. The star has the designation 122 G. Virginis. There are no stars with a Gould designation in Ursa Major for example.

BD number is the number that the star was filed under in the Durchmusterung or Bonner Durchmusterung, a star catalogue that was put together by the Bonn Observatory between 1859 to 1903. The star's BD Number is BD-09 3646.

Location of 56 Virginis

The location of the star in the galaxy 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 56 Virginis, the location is 13h 14m 45.13 and -10° 22` 13.0 .

Proper Motion of 56 Virginis

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 -44.13 ± 0.33 miliarcseconds/year towards the north and -22.45 ± 0.50 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 us is 27.30000 km/s with an error of about 3.00 km/s .

56 Virginis Luminosity

Luminosity is the amount of energy that a star pumps out and its relative to the amount that our star, the Sun gives out. The figure of 184.5200000 that I have given is based on the value in the Simbad Hipparcos Extended Catalogue at the University of Strasbourg from 2012.

Physical Properties (Colour, Temperature) of 56 Virginis

56 Virginis has a spectral type of K5. This means the star is a orange to red star. The star is 7319.00000000 Parsecs from the Galactic Centre or terms of Light Years is 23871.8951473600000000s. The star has a B-V Colour Index of 1.54 which means the star's temperature has been calculated using information from Morgans @ Uni.edu at being 3,926 Kelvin.

56 Virginis Radius has been calculated as being 16.71 times bigger than the Sun.The Sun's radius is 695,800km, therefore the star's radius is an estimated 11,627,416.10.km. The figure is derived at by using the formula from SDSS and has been known to produce widely incorrect figures.

56 Virginis Apparent and Absolute Magnitudes

56 Virginis has an apparent magnitude of 6.95 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. Using the supplied Parallax value, you would get an absolute magnitude of 0.41 Magnitude, whether it be apparent/visual or absolute magnitude is measured by a number, the smaller the number, the brighter the Star is. Our own Sun is the brightest star and therefore has the lowest of all magnitudes, -26.74. A faint star will have a high number.

Distance to 56 Virginis

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 4.93 which gave the calculated distance to 56 Virginis as 661.59 light years away from Earth or 202.84 parsecs. It would take a spaceship travelling at the speed of light, 661.59 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.

The star's Galacto-Centric Distance is 7,319.00 Parsecs or 23,871.90 Light Years. The Galacto-Centric Distance is the distance from the star to the Centre of the Galaxy which is Sagittarius A*.

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.
