Elnyom

Elnyom, also known as Elnath, is a star located in the constellation Taurus. It is the second brightest star in the constellation, with an apparent magnitude of 1.65, making it easily visible to the naked eye. Elnyom is a binary star system, consisting of a primary star, Elnath A, and a secondary star, Elnath B.

Elnath A is a blue-white giant star with a spectral type of B7III. It has a mass approximately 5.5 times that of the Sun and a radius about 4.5 times larger. The star is relatively young, with an estimated age of around 100 million years. Elnath B is a fainter companion star, with an apparent magnitude of 11.4. It is a main-sequence star of spectral type A5V, with a mass about 1.8 times that of the Sun.

The name Elnyom is derived from the Arabic phrase "al-nath," which means "the butting." This name reflects the star's position in the constellation Taurus, which is often depicted as a bull. In ancient times, Elnyom was considered one of the horns of the bull. The star is also known by its Bayer designation, Beta Tauri, which indicates that it is the second brightest star in Taurus.

Elnyom is located approximately 136 light-years away from Earth. Despite its relative proximity, the star is not visible from the Southern Hemisphere due to its high northern declination. The star's binary nature and its position in the constellation make it an interesting object for astronomers and stargazers alike.
