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.
The three bright stars, Alnitak, Alnilam and Mintaka. They are also referred to as Delta, Epsilon and Zeta Orionis. They all lie on or close to the Celestial Equator.
The three stars in Orion's Belt are named Alnitak, Alnilam, and Mintaka. They are also known as Zeta Orionis, Epsilon Orionis, and Delta Orionis, respectively. These stars are some of the most prominent in the constellation Orion.
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.
The first component of the TZ Orionis system to be discovered was TZ Orionis A, which is a spectroscopic binary system. The second component, TZ Orionis B, was later identified as a visual binary companion to TZ Orionis A.
An example of a bluish-white star is Sirius, which is the brightest star in the night sky and part of the constellation Canis Major. It has a notable blue-white color due to its high surface temperature compared to other stars.

There is no star with that name. Many stars have names that start with "Epsilon", followed by the genitive of a constellation, e.g. "Epsilon Cruxis", "Epsilon Geminorum", etc. If its epsilon segin cassiopeia, it is 520L/Y(light years) away from earth.
Alnilam (Epsilon Orionis) is a large blue supergiant star in the constellation of Orion.It has a spectral type of B0.See related link for more information.

Alpha Orionis (α Orionis, α Ori)
The first component of the TZ Orionis system to be discovered was TZ Orionis A, which is a spectroscopic binary system. The second component, TZ Orionis B, was later identified as a visual binary companion to TZ Orionis A.
The three bright stars in the belt are Delta, Epsilon, and Zeta Orionis, also known as Mintaka, Alnilam, and Alnitak respectively. The stars are named from north to south (or west to east; from Orion's left to his right).
Alioth or Epsilon Ursae Majoris
An example of a bluish-white star is Sirius, which is the brightest star in the night sky and part of the constellation Canis Major. It has a notable blue-white color due to its high surface temperature compared to other stars.
V
The star Rigel can also be called β Orionis or Beta Orionis.
