Eta Carinae

Eta Carinae Facts

Location of Eta Carinae

The location of the 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 Eta Carinae, the location is 10h 45m 03 and -59° 41` 04 .

Physical Properties (Colour, Temperature, Age) of Eta Carinae

Eta Carinae has a spectral type of O. This means the star is a blue star. Eta Carinae 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 0.61 which means the star's temperature has been calculated using information from Morgans @ Uni.edu at being 5,852 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.

Eta Carinae Apparent and Absolute Magnitudes

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.

Meteor Showers Radiating from near Eta Carinae

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 Eta Carinae

Eta Carinae 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.
