未来,木星会取代太阳吗?

    ①在太阳系中,木星是行星中的“巨无霸”。它的体积和质量分别达到了地球的1320倍和318倍。不过,除此以外,木星的独特之处还在于它能发光,有自己的能源。

    ②也许你并不觉得这是什么稀罕事,那么我们先来看一下行星的定义:行星通常是指自身不发光、环绕着恒星的天体。其公转方向常与所绕恒星的自转方向相同。一般来说行星需具有一定质量,行星的质量要足够的大且近似于圆球状,自身不能像恒星那样发生核聚变反应。在人们的通常认识中,行星的确不能发光,只能依靠反射太阳的光线。但科学家研究发现,木星正在把巨大的能量不断地向周围的宇宙空间释放,它释放的能量,相当于两倍从太阳那里所获得的能量,说明木星有一半的能量来自它的内部。

    ③分别于1972年和1973年发射的“先驱者”10号与11号飞船探测的结果显示,液态氢构成了整个木星。它同太阳一样,没有坚硬的外壳,主要是通过对流形式来实现能量的释放。前苏联科学家齐巴罗夫和苏齐科夫认为,木星的核心温度已达到30000℃之高,热核反应还在其内部继续进行。

    ④那么,我们不禁要问一个严肃的问题:未来,木星会渐渐取代太阳吗?

    ⑤正如之前所说,木星是由液态氢构成的,本身并无坚硬的外壳。木星的这种构成与太阳构成方式十分相似,主要是通过对流形式来实现能量的释放。木星不仅把自己的引力能转换成热能,还在不断吸收太阳释放的能量,这就使它的能量越来越大,且热度越来越高,并使它达到了现在的高度。从木星目前的发展趋势看,它很可能成为太阳系中与太阳相差无几的第二颗恒星。

    ⑥30亿年以后,太阳到了晚年,木星很可能取代太阳的地位。虽然时间还很远,但人类不得不面对一个事实是,太阳已经是一颗垂暮的恒星了,它的光辉总有一天会熄灭,而木星的自带光源,点燃了生命顽强延续下去的希望。
