In a very broad sense, a star is simply one of those twinkling points of light you can see in the night sky But that’s not terribly satisfying in either lexicological or physical terms.
The simplest way to describe a star is that it is a great ball of fire, but it is more complicated than that A star is a giant ball of hydrogen turning into helium through nuclear fusion.

A star is a massive, luminous ball of plasma that is held together by its own gravity The nearest star to earth is the sun, which is the source of most of the energy on earth Other stars are visible in the night sky, when they are not outshone by the sun. An ordinary star is a massive sphere of luminous gas, mainly hydrogen and helium.
Where do stars come from Every star forms in a huge cloud of gas and dust Over time, gravity causes the cloud to contract, drawing the gas closer and closer together
