V354 Cephei

V354 Cephei is a red supergiant star that can be located in the constellation of Cepheus. The description is based on the spectral class. The star can not be seen by the naked eye, you need a telescope to see it.

Location of V354 Cephei

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 V354 Cephei, the location is 22h 33m 34.6 and 58° 53` 47.05 .

Physical Properties (Colour, Radius) of V354 Cephei

V354 Cephei has a spectral type of M2.5 Iab. This means the star is a red supergiant star. V354 Cephei lies at a distance of 9,000.00 light years away from our Sun and our planet Earth or to put it another way, 2,759.35 parsecs away from the Sun.

V354 Cephei has been calculated as 1,520.00 times bigger than the Sun.The Sun's radius is 695,800km, therefore the star's radius is an estimated 1,057,616,000.00.km. If you need the diameter of the star, you just need to multiple the radius by 2.

V354 Cephei Apparent and Absolute Magnitudes

V354 Cephei has an apparent magnitude of 10.82 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 V354 Cephei

V354 Cephei is an estimated 9,000.00 light years from our Solar System (Earth and Sun). It would take a spaceship 9,000.00 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.
