V354 Cephei
Facts
- V354 Cephei is a very luminous Supergiant Star type star. V354 Cephei is a M2.5 IAB supergiant star based on the spectral type that was recorded in Simbad at Strasbourg University.
- V354 Cephei is not part of the Cepheus constellation outline but is within the borders of the constellation.
- Based on the spectral type (M2.5 Iab) of the star, the star's colour is red .
- The star can not be seen by the naked eye, you need a telescope to see it.
- V354 Cephei has a radius that is 1,520.00 times bigger than the Suns.
Location
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 V354 Cephei, the location is 22h 33m 34.6 and 58° 53` 47.05 .
Physical Properties
Colour
Based on the star's spectral type of M2.5 Iab , V354 Cephei's colour and type is red supergiant star. Based on the spectral type, we can deduce that the surface temperature of the star is in the order of between below 3,500K based on the notes from Harvard University. To put this in context, the temperature of our Sun is about 5,778 Kelvin as said by Google.
Radius
V354 Cephei Radius has been calculated as being 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.
Apparent (Brightness) and Absolute Magnitudes
V354 Cephei has an apparent magnitude of 10.82, this is a measure of the brightness of the star as seen from Earth. Apparent Magnitude is also known as Visual Magnitude.
Absolute Magnitude is the apparent magnitude of the star from a distance of 10 parsecs or 32.6 light years. This assumes that there is nothing in between the object and the viewer such as dust clouds. To really compare the brightness of the star, it is best to use Absolute rather than Apparent 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.
Alternative Names and Meanings
- The V indicates that the star is a variable star and its position in the catalog (General Catalog of Variable Stars).
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.
Comparison Between V354 Cephei and The Sun
Below is a tabular view of the star facts with the values of the Sun on the right so you can compare against our own star, the Sun. The Sun is our nearest star and it is what keeps us warm and gives us light as we complete one orbit in 365.24 days.
If you want to see the comparison between V354 Cephei and our star, the Sun, you will need a screen of at least 800px across. Rotating your screen maybe sufficient to see the Stellar values for comparison.
