HD 95086, HIP53524

HD 95086 is a blue giant star that can be located in the constellation of Carina. The star can not be seen by the naked eye, you need a telescope to see it. It is calculated at being .017 Billion Years old. This information comes from ExoPlanet.

HIP53524 is the reference name for the star in the Hipparcos Star Catalogue. The Id of the star in the Henry Draper catalogue is HD95086. HD 95086 has at least 1 Extrasolar Planets believed to be in orbit around the star.

Location of HD 95086

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 HD 95086, the location is 10h 57m 03.09 and -68d40`02.6 .

Proper Motion of HD 95086

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 12.47 ± 0.34 miliarcseconds/year towards the north and -41.41 ± 0.41 miliarcseconds/year east if we saw them in the horizon.

Physical Properties (Colour, Temperature, Age, Mass, Radius) of HD 95086

HD 95086 has a spectral type of A8III. This means the star is a blue giant star. The star is 7366.00000000 Parsecs from the Galactic Centre or terms of Light Years is 24025.1919190400000000s. The star has a B-V Colour Index of 0.23 which means the star's temperature has been calculated using information from Morgans @ Uni.edu at being 7,593 Kelvin.

HD 95086 Radius has been calculated as being 1.67 times bigger than the Sun.The Sun's radius is 695,800km, therefore the star's radius is an estimated 1,160,208.37.km. However with the 2007 release of updated Hipparcos files, the radius is now calculated at being round 1.64. The figure is derived at by using the formula from SDSS and has been known to produce widely incorrect figures. The star's solar mass is 1.60 times that of the Sun's. The Sun's Mass is 1,989,100,000,000,000,000,000 billion kg. which to calculate using this website is too large. To give idea of size, the Sun is 99.86% the mass of the solar system.

The star is believed to be about 0.02 Billion years old. To put in context, the Sun is believed to be about five billion years old and the Universe is about 13.8 billion years old.

HD 95086 Apparent and Absolute Magnitudes

HD 95086 has an apparent magnitude of 7.36 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. If you used the 1997 Parallax value, you would get an absolute magnitude of 2.55 If you used the 2007 Parallax value, you would get an absolute magnitude of 2.58. 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 HD 95086

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 10.92 which gave the calculated distance to HD 95086 as 298.68 light years away from Earth or 91.58 parsecs. It would take a spaceship travelling at the speed of light, 298.68 years to get there. We don't have the technology or spaceship that can carry people over that distance yet.

In 2007, Hipparcos data was revised with a new parallax of 11.06 which put HD 95086 at a distance of 294.90 light years or 90.42 parsecs. It should not be taken as though the star is moving closer or further away from us. It is purely that the distance was recalculated.

The star's Galacto-Centric Distance is 7,366.00 Parsecs or 24,025.19 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.
