The star generates more energy than our star. ' The figure of 29.163 comes from the Vizier online catalogue. Luminosity is the amount of energy a star pumps out relative to the amount that our star, the Sun, gives out. Okab's effective temperature is 6,300 Kelvin which is hotter than our own Sun's effective temperature, which is 5,777 Kelvin. Small stars are more energy efficient than larger stars and live longer. For example, a red star can be large or small. There is no relationship between colour and size. As the Earth is titled, we therefore have Celestial and Ecliptic hemispheres and they can be different for a star.īased on the star's spectral type of A0Vn, Okab's colour and type is blue - white main sequence star. The Ecliptic is the path that the Earth takes as it orbits the Sun. Being in the equatorial region, the star can be seen in both terrestrial hemispheres but there is a caveat of depending how far south and north you are. The celestial hemisphere is equivalent to the hemispheres on Earth. īased on the location of Aquila, Okab can be located in the equatorial region of the celestial sky. If the value is positive, it is north of the celestial equator. The Declination (Latitude) is how far north or south the object is compared to the celestial equator and is expressed in degrees. is positive, then it's eastwards and vice versa. The Right Ascension (Longitude) is expressed in time (hh:mm:ss) and is how far the star is along Earth's celestial equator. These are equivalent to the Longitude and Latitude on Earth. The location of the Okab in the night sky is determined by the right ascension (R.A.) and declination (Dec.). The name is shared between this star and Epsilon Aquilae which is in the same constellation as this one. If Okab is a typical blue star (A Type) then this star would probably have a lifespan of a mere 10 million years, they are short lived stars.Changing the distance from light years to years will tell you roughly how long ago we are looking at the star. Using the most recent figures from the 2007 Hipparcos data, Okab distance from Earth is 83.04 light years. When you look at Okab, you are looking back in time and seeing how it looked years ago.The radius of Okab is 4.53 times bigger than the Sun.No one has visited Okab, and we have no probes on a rendezvous with the star.If an exoplanet has been spotted or confirmed, it will probably be recorded in the Exoplanet EU database. There are no exoplanets recorded on the site for the star, and that is most likely the case.In case you're wondering, Okab is not in our Solar System, and there is only one star in the Solar System, the Sun. Okab is located in the Milky Way galaxy, and this is the galaxy that you reside in.
