FS Eridani Facts

FS Eridani's Alternative Names

HIP14055 is the reference name for the star in the Hipparcos Star Catalogue.

FS Eridani has alternative name(s) :- , FS Eri.

More details on objects' alternative names can be found at Star Names .

Location of FS Eridani

The location of the variable star in the night sky 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 object is compared to the celestial equator and is expressed in degrees. For FS Eridani, the location is 03h 01m 03.84 and -41° 21` 05.5 .

Physical Properties (Temperature) of FS Eridani

FS Eridani Colour and Temperature

FS Eridani has a spectral type of R.... The star has a B-V Colour Index of 1.69 which means the star's temperature has been calculated using information from Morgans @ Uni.edu at being 3,492 Kelvin.

FS Eridani Apparent and Absolute Magnitudes

FS Eridani has an apparent magnitude of 8.69 which is how bright we see the star from Earth. Apparent Magnitude is also known as Visual Magnitude. Using the supplied Parallax value, you would get an absolute magnitude of 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.

Distance to FS Eridani

Using the original Hipparcos data that was released in 1997, the parallax to the star was given as -0.85 which gave the calculated distance to FS Eridani as -3837.22 light years away from Earth or -1176.47 parsecs. It would take a spaceship travelling at the speed of light, -3837.22 years to get there. We don't have the technology or spaceship that can carry people over that distance yet. FS Eridani brightness ranges from a magnitude of 8.829 to a magnitude of 8.731 over its variable period. The smaller the magnitude, the brighter the star. Its variable/pulsating period lasts for 0.1 days (variability).

Source of Information

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 Metallicity and/or Mass is from the E.U. Exoplanets. The information was obtained as of 12th Feb 2017.
