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. Other stars are visible from Earth during the night, when they are not obscured by atmospheric phenomena, appearing as a multitude of fixed luminous points because of their immense distance. Historically, the most prominent stars on the celestial sphere were grouped together into constellations and asterisms, and the brightest stars gained proper names. Extensive catalogues of stars have been assembled by astronomers, which provide standardized star designations.

For at least a portion of its life, a star shines due to thermonuclear fusion of hydrogen in its core releasing energy that traverses the star's interior and then radiates into outer space. Almost all naturally occurring elements heavier than helium were created by stars, either via stellar nucleosynthesis during their lifetimes or by supernova nucleosynthesis when stars explode. Astronomers can determine the mass, age, chemical composition and many other properties of a star by observing its spectrum, luminosity and motion through space. The total mass of a star is the principal determinant in its evolution and eventual fate. Other characteristics of a star are determined by its evolutionary history, including diameter, rotation, movement and temperature. A plot of the temperature of many stars against their luminosities, known as a Hertzsprung–Russell diagram (H–R diagram), allows the age and evolutionary state of a star to be determined.

Kailash Kher(born 7 July 1973) is an Indian pop-rock singer with a music style influenced by Indian folk music. He has sung in 18 languages for regional films, and over now 300 songs for the Bollywood.

Kher’s father Mr. Mehar Singh, a Hindu priest, was an amateur musician whose performances of traditional folk songs were a regular household event.

Kailash used to learn music from him in his childhood. Kailash Kher was brought up in a musical atmosphere and from his school days he was fascinated by music and used to listen to his father's Indian folks songs all the day. Even as a four year old, Kher revealed a natural musical talent and he would often impress friends and family by belting out songs with his prematurely powerful voice.
