WX Leporis, HD37622, HIP26612

WX Leporis is a blue eclipsing binary sys main sequence dwarf star that can be located in the constellation of Lepus. The description is based on the spectral class. WX Leporis is not part of the constellation 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.

WX Leporis's Alternative Names

HIP26612 is the reference name for the star in the Hipparcos Star Catalogue. The Id of the star in the Henry Draper catalogue is HD37622.

WX Leporis has alternative name(s) :- , WX Lep.

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-11 1251.

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

Location of WX Leporis

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 WX Leporis, the location is 05h 39m 25.09 and -11° 12` 36.8 .

Radial Velocity and Proper Motion of WX Leporis

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 1.88 ± 0.41 miliarcseconds/year towards the north and 1.67 ± 0.55 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 32.00 km/s with an error of about 5.60 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, Temperature) of WX Leporis

WX Leporis has a spectral type of B3Vn. This means the star is a blue main sequence dwarf star. The star has a B-V Colour Index of -0.07 which means the star's temperature has been calculated using information from Morgans @ Uni.edu at being 10,845 Kelvin.

WX Leporis Radius has been calculated as being 26.70 times bigger than the Sun.The Sun's radius is 695,800km, therefore the star's radius is an estimated 18,577,103.53.km. If you need the diameter of the star, you just need to multiple the radius by 2. The figure is derived at by using the formula from SDSS and has been known to produce widely incorrect figures.

WX Leporis Apparent and Absolute Magnitudes

WX Leporis has an apparent magnitude of 7.99 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 -5.02 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 WX Leporis

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 0.25 which gave the calculated distance to WX Leporis as 13046.53 light years away from Earth or 4000 parsecs. It would take a spaceship travelling at the speed of light, 13046.53 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.

Variable Type of WX Leporis

The star is a eclipsing binary sys Beta Lyrae (Sheliak) variable type which means that its size changes over time. The Variable Type is usually named after the first star of that type to be spotted. WX Leporis brightness ranges from a magnitude of 8.023 to a magnitude of 7.925 over its variable period. The smaller the magnitude, the brighter the star. Its variable/pulsating period lasts for 1.8 days (variability).

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.
