Westerlund 1-26 Facts

Location of Westerlund 1-26

The location of the supergiant 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 Westerlund 1-26, the location is 16h 47m 05.40 and -45° 50` 36.76 .

Physical Properties (Colour, Radius) of Westerlund 1-26

Westerlund 1-26 Colour and Temperature

Westerlund 1-26 has a spectral type of M2-M6Ia. This means the star is a red supergiant star. Westerlund 1-26 lies at a distance of 11,500.00 light years away from our Sun and our planet Earth or to put it another way, 3,525.84 parsecs away from the Sun.

Westerlund 1-26 Radius

Westerlund 1-26 has been calculated as 1,530.00 times bigger than the Sun. The Sun's radius is 695,800km, therefore the star's radius is an estimated 1,064,574,000.00.km. If you need the diameter of the star, you just need to multiple the radius by 2.

Westerlund 1-26 Apparent and Absolute Magnitudes

Westerlund 1-26 has an apparent magnitude of 17.19 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 Westerlund 1-26

Westerlund 1-26 is an estimated 11,500.00 light years from our Solar System (Earth and Sun). It would take a spaceship 11,500.00 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.
