11 Leonis Minoris - HD82885 - HIP47080

11 Leonis Minoris is a white to yellow subgiant star that can be located in the constellation of LeoMinor. 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.

Location of 11 Leonis Minoris

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 11 Leonis Minoris, the location is 09h 35m 40.03 and +35 d 48 ` 38.8 .

Physical Properties/View of 11 Leonis Minoris

11 Leonis Minoris has a spectral type of G8IV-V. This means the star is (G) white to yellow coloured (IV) subgiant. 11 Leonis Minoris lies at a distance of 36.46 light years away from our Sun and our planet Earth or to put it another way, 11.04 parsecs away from the Sun.

11 Leonis Minoris has an apparent magnitude of 5.40 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. 11 Leonis Minoris has an absolute magnitude of 5.16 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 star's effective temperature is 5,370 Kelvin which is cooler than our own Sun's effective Temperature which is 5,777 Kelvin

11 Leonis Minoris Radius has been calculated as being 1.06 times bigger than the Sun. The Sun's radius is 695,800km, therefore the star's radius is an estimated 737,547.96. km. The star's solar mass is 1.00 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.

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.
