13 Sextantis - HD87301 - HIP49329

13 Sextantis is a blue to white main sequence dwarf star that can be located in the constellation of Sextans. HIP is the reference name for the star in the Hipparcos Star Catalogue. The Id of the star in the Henry Draper catalogue is HD. 13 Sextantis has alternative name(s), 13 Sextantis.

Location of 13 Sextantis

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 from celestial equator. The Declination is how up or down compared to the celestial equator and is expressed in degrees. For 13 Sextantis, the location is 10h 04m 08.48 and +03 d 12 ` 04.6 .

Physical Properties/View of 13 Sextantis

13 Sextantis has a spectral type of F4V. This means the star is (F) blue to white coloured (V) main sequence (dwarf star). 13 Sextantis lies at a distance of 179.21 light years away from our Sun and our planet Earth or to put it another way, 54.88 parsecs away from the Sun.

13 Sextantis has an apparent magnitude of 6.43 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. 13 Sextantis has an absolute magnitude of 2.73 which is the apparent magnitude of an object if it were 32.6 light years away or 10 parsecs from Earth. 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. The stars temperature has been calculated at between 6000 and 7500 based on the Class Type and lookup at Wikipedia-Stellar Classification

Source of Information

The source of the information came 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.
