Kappa Orionis (Saiph) is a type B0 star, which means it has a colour of blue-white and a temperature of 10,000--30,000 K
The star Rigel can also be called β Orionis or Beta Orionis.
There are 81 stars in the constellation which appear in the Bayer/Flamsteed catalogues. Eight of these are brighter than an apparent magnitude of 3.0 The seven which from the notable hour-glass outline are:Betelgeuse (Alpha Orionis).Rigel (Beta Orionis)Bellatrix (Gamma Orionis),Mintaka (Delta Orionis),Alnilam (Epsilon Orionis),Alnitak (Zeta Orionis) andSaiph (Kappa Orionis).Of course, as with any constellation, there are stars which are so faint that they have not yet been detected and so have not had their magnitudes measured.
Gamma Orionis (Bellatrix), is a blue-tinted white supergiant in the constellation Orion.It has a spectral class of B2
Epsilon Orionis and Rigel
Epsilon Orionis(Alnilam) is a large blue star in the constellation of Orion. It is the centre star of Orions belt.It has a radius about 26 times larger than our own Sun.
Kappa Orionis (Saiph) is the sixth brightest star in the constellation of Orion.It has a spectral type of B0 which means it is at the top end of the B-class spectral range.See related link for more information.
Kappa Orionis (Saiph) is the sixth brightest star in the constellation of Orion.It is located approximately 700 light years from us.
When astronomers named the brighter stars they often used a Greek letter like alpha or kappa or upsilon. But they also added a constellation name. e.g. Upsilon Orionis, Upsilon Centauri. To answer your question, we need to know in which constellation this star is.
The star Rigel can also be called β Orionis or Beta Orionis.
