[1] the nearest star to earth is the sun But that’s not terribly satisfying in either lexicological or physical terms. Many other stars are visible to the naked eye at night
Their immense distances from earth make them appear as fixed points of light. In a very broad sense, a star is simply one of those twinkling points of light you can see in the night sky Of the tens of billions of trillions of stars in the observable universe, only a very small percentage are visible to the naked eye.
But there are different ways a star’s life can end, and its fate depends on how massive the star is. A star is a huge sphere of very hot, glowing gas Stars produce their own light and energy by a process called nuclear fusion Fusion happens when lighter elements are forced to become heavier elements
When this happens, a tremendous amount of energy is created causing the star to heat up and shine Stars come in a variety of sizes and colors. 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.
