Eta Carinae is a main sequence dwarf star that can be located in the constellation of Carina. The star can be seen with the naked eye, that is, you don't need a telescope/binoculars to see it.
Eta Carinae is the Bayer Classification for the star. The Id of the star in the Yale Bright Star Catalogue is HR4210.
More details on star alternative names can be found at Star Names.
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 Eta Carinae, the location is 10h 45m 03.59 and -59 ° 41` 04.26 .
Eta Carinae has a spectral type of LBV. 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 5,859 Kelvin.
Eta Carinae has been calculated as 60.00 times bigger than the Sun.The Sun's radius is 695,800km, therefore the star's radius is an estimated 41,748,000.00.km.
Eta Carinae has an apparent magnitude of 6.37 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.
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. p>
