Foramen (Eta Carinae) - HD93308

Foramen (Eta Carinae) is a blue star that can be located in the constellation of Carina. It is calculated at being .300 Billion Years old. This information comes from ExoPlanet. Eta Carinae is the Bayer Classification for the star. The Id of the star in the Henry Draper catalogue is HD93308.

Location of Foramen

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 Foramen, the location is 10h 45m 03 and -59d 41` 04 .

Physical Properties (Colour, Temperature, Age, Radius) of Foramen

Foramen has a spectral type of O. This means the star is a blue star. Foramen lies at a distance of 7,500.00 light years away from our Sun and our planet Earth or to put it another way, 2,299.46 parsecs away from the Sun. The star has a B-V Colour Index of -0.45 which means the star's temperature has been calculated using information from Morgans @ Uni.edu at being 159,978 Kelvin.

The star is believed to be about 0.30 Billion years old. To put in context, the Sun is believed to be about five billion years old and the Universe is about 13.8 billion years old.

Meteor Showers Radiating from near Foramen

The Eta Carinids Meteor Shower radiants from a point near this star. The meteor shower runs typically between 14-Jan - 27 Jan with a peak date of 21 - Jan.

Distance to Foramen

Foramen is an estimated 7,500.00 light years from our Solar System (Earth and Sun). It would take a spaceship 7,500.00 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.

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