A star represents the "heavens." This is in reference to the biblical instruction, Genesis 1:1, which mentions "In the beginning, God created the heavens and the earth." Various celestial bodies including comets, galaxies and stars are referred to as the "heavens."
Stars can have any number of points. In Christianity, the five-pointed star, which is called the Star of Bethlehem, is used to symbolize the reincarnation and birth of Jesus Christ. The four-pointed star is used as a cross in Christianity, and it represents the purpose for which Jesus Christ was born.
In Western culture, a five-pointed star is used as a symbol of fame, as evidenced on the Hollywood Walk of Fame. Famous celebrities are honored with a five-pointed star of pink terrazzo for their contribution to the entertainment industry.
