. It is a G-type bright giant
star
approximately 159 light-years from the Earth
and has an apparent visual magnitude of approximately 2.84.
It is also known as Nihal,"quenching their thirst". The occasional spelling Nibal appears to be due to a misreading.

Star
A star is a massive, luminous sphere of plasma held together by gravity. At the end of its lifetime, a star can also contain a proportion of degenerate matter. The nearest star to Earth is the Sun, which is the source of most of the energy on Earth...

Double star
In observational astronomy, a double star is a pair of stars that appear close to each other in the sky as seen from Earth when viewed through an optical telescope. This can happen either because the pair forms a binary star, i.e...
