Are other stars the same as our sun? Stars are distant Suns, but so far away they look like points of light. They are giant balls of hot gas, just like our Sun. They are also like people. They are born, live through a long middle age, and finally die. Some stars are alone, like our Sun, and others have a constant companion, usually another star. Stars also change as they age. These changes take place over millions and billions of years so we don't notice them.
