Sneden's Star is a orange to red luminous giant star that can be located in the constellation of Aquarius. The star can not be seen by the naked eye, you need a telescope to see it.
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 Sneden's Star, the location is 22h 17m 1.5 and -16 d 39`26 .
Sneden's Star has a spectral type of KIIvw. This means the star is a orange to red luminous giant star. Sneden's Star lies at a distance of 15,329.52 light years away from our Sun and our planet Earth or to put it another way, 4,699.95 parsecs away from the Sun.
Sneden's Star has an apparent magnitude of 13.20 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. 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.
Sneden's Star is an estimated 15,329.52 light years from our Solar System (Earth and Sun). It would take a spaceship 15,329.52 years travelling at the speed of light to get there. We don't have a space ship that can travel that distance or at that speed yet.
