10 Puppis is a blue to white subgiant star that can be located in the constellation of Puppis. HIP38427 is the reference name for the star in the Hipparcos Star Catalogue. The Id of the star in the Henry Draper catalogue is HD64238. The Id of the star in the Gould Star Catalogue is 206. Stars in the southern hemisphere are more likely to have a Gould Id than the northern hemisphere. For example, there are no Gould classified stars in Ursa Major. 10 Puppis has alternative name(s), 10 Puppis , 10 Pup.
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 10 Puppis, the location is 07h 52m 18.88 and -14 d 50 ` 46.2 .
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 001.00 ± 000.00 towards the north and -007.00 ± 000.00 east if we saw them in the horizon.
10 Puppis has a spectral type of F2IV/V. This means the star is a blue to white coloured subgiant star. The star has a B-V Colour Index of 0.36 which means the star's temperature has been calculated using information from Morgans @ Uni.edu at being 6,918 Kelvin.
10 Puppis has been calculated as 15.74 times bigger than the Sun.The Sun's radius is 695,800km, therefore the star's radius is an estimated 10,950,792.87.km.
10 Puppis has an apparent magnitude of 5.69 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 -1.92 If you used the 2007 Parallax value, you would get an absolute magnitude of -1.92. 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.
Using the original Hipparcos data that was released in 1997, the parallax to the star was given as 3.00 which gave the calculated distance to 10 Puppis as 1087.21 light years away from Earth or 333.33 parsecs. In 2007, Hipparcos data was revised with a new parallax of 3.00 which put 10 Puppis at a distance of 1087.21 light years or 333.33 parsecs.
It would take a spaceship travelling at the speed of light, 1087.21 years using the 1997 distance to get there. We don't have the technology or spaceship that can carry people over that distance yet.
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 Stellar Age, Metallicity or Mass is from the E.U. Exoplanets. The information was obtained as of 12th Feb 2017.
