WR25 is a blue supergiant star that can be located in the constellation of Carina. The description is based on the spectral class. WR25 is not part of the constellation but is within the borders of the constellation.

The star can not be seen by the naked eye, you need a telescope to see it.

Location of WR25

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 star is compared to the celestial equator and is expressed in degrees. For WR25, the location is 10h 44m 10.337 and -59° 43` 11.41 .

Physical Properties (Colour, Radius) of WR25

WR25 has a spectral type of O2.5If*/WN6 + OB. This means the star is a blue supergiant star. WR25 lies at a distance of 10,500.00 light years away from our Sun and our planet Earth or to put it another way, 3,219.25 parsecs away from the Sun.

WR25 has been calculated as 33.00 times bigger than the Sun.The Sun's radius is 695,800km, therefore the star's radius is an estimated 22,961,400.00.km. If you need the diameter of the star, you just need to multiple the radius by 2.

WR25 Apparent and Absolute Magnitudes

WR25 has an apparent magnitude of 8.80 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.

Distance to WR25

WR25 is an estimated 10,500.00 light years from our Solar System (Earth and Sun). It would take a spaceship 10,500.00 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.
