The scientists at E.S.O. have captured what they believe is the first image of an extrasolar planet in orbit round another star. Whilst we know about the other planets from wobbles in the star, this is the first that an exoplanet has been photographed. Previous pictures have been of artist impressions, this is the first that we see. Its not much but we`ll get better at taking photos. The star is in the constellation of Orion, the Hunter and the star is just slightly up from the famous Orions Belt.
The star is just known by its letters at the moment but I`m sure that the star will get a new name when the IAU start a new star name competition. All the other important stars with exoplanets have received new names such as 51 Pegasi -> Helvetios, 55 Cancri -> Copernicus. The planet is barely visible with a powerful Southern Observatory, its not going to be seen through the telescopes you buy over the counter so don`t spend time looking. More information can be found at E.S.O., you may need a translator.
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 CVSO 30, the location is 05h 25m 07.557 and +01 ° 34` 24.33 .
CVSO 30 has a spectral type of M3. This means the star is a red star.
CVSO 30 has been calculated as 1.39 times bigger than the Sun. The Sun's radius is 695,800km, therefore the star's radius is an estimated 967,162.00.km. If you need the diameter of the star, you just need to multiple the radius by 2.
CVSO 30 has an apparent magnitude of 16.26 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.
