107 Piscium is an orange to red main sequence dwarf star that can be located in the constellation of Pisces. HIP7981 is the reference name for the star in the Hipparcos Star Catalogue. The Id of the star in the Henry Draper catalogue is HD10476. 107 Piscium has alternative name(s), 107 Piscium , 107 Psc.
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 107 Piscium, the location is 01h 42m 29.95 and +20 d 16 ` 12.5 .
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 -679.00 ± 000.00 towards the north and -302.00 ± 001.00 east if we saw them in the horizon.
107 Piscium has a spectral type of K1V. This means the star is an orange to red coloured main sequence dwarf star. The star has a B-V Colour Index of 0.83 which means the star's temperature has been calculated using information from Morgans @ Uni.edu at being 5,212 Kelvin.
107 Piscium has been calculated as 0.76 times bigger than the Sun.The Sun's radius is 695,800km, therefore the star's radius is an estimated 531,277.34.km.
107 Piscium has an apparent magnitude of 5.24 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 5.88 If you used the 2007 Parallax value, you would get an absolute magnitude of 5.86. 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 134.00 which gave the calculated distance to 107 Piscium as 24.34 light years away from Earth or 7.46 parsecs. In 2007, Hipparcos data was revised with a new parallax of 133.00 which put 107 Piscium at a distance of 24.52 light years or 7.52 parsecs.
It would take a spaceship travelling at the speed of light, 24.34 years using the 1997 distance to get there. We don't have the technology or spaceship that can carry people over that distance yet.
