SOLAR SYSTEM'S ETERNAL SHOW IN A BREAKUP OF THE SUN. THE EARTH AND PLANETS MAY HAVE BEEN BORN In the distant past, according to one theory, the Sun was rotating so fast that it began to fly apart. Huge bulges developed on it, as shown here. AS THE SUN BROKE INTO TWO STARS, SMALLER FRAGMENTS ALSO WERE EJECTED These became the planets. Tidal forces slowed down the rotation of the two large masses, and. some of their momentum was transferred to the newborn worlds.
