A planet on the other hand is built up out of the dust that surrounds a star. When a star is formed there is still a disk of gas surrounding it. As this gas cools, it condenses and forms solid grains. These grain particles accrete into large bodies called planetesimals, which then collide and accrete to make protoplanets. These protoplanets evolve into planets like the planets in our own solar system.
行星演化与恒星不同:恒星形成之后,周边的气体尘埃云冷却之后凝结形成,成为行星雏形,众多小行星雏形聚合碰撞,演化成成熟的行星;没有内部的核聚变;质量超过木星13.6倍,就会产生核聚变,如果还未至木星86倍,尚处于棕矮星的阶段,将会向恒星演化;持久的核聚变需要足够大的质量来支撑,温度也不足支撑氢向氦的转变。
