宇宙中充满了奇奇怪怪的东西。有超速度的恒星——它们不是流星，顺便说一下，是像覆盆子一样的尘雾，闻起来像朗姆酒。世界上有更多的声音是绝对不可能的(双关语)。还有太阳系之外的行星，它们很神秘。在AlexanderWolszczan博士于年发现了太阳系的前三颗行星之后，在过去的十多年里，太阳系外的这些奇怪而神秘的行星被发现。让我们来看看太阳系外10个奇怪而神秘的行星。

TheCoRoT-7bisastrangeandmysteriousplanetoutsidethesolarsystem,andthefirstrockyplanetdiscoveredorbitingastarotherthantheSun.据信，它最初是一颗巨大的气态行星，像海王星或土星，但由于它靠近它的宿主，它逐渐失去了气体和大气层。因为它是潮锁,它总是面临其恒星一侧温度可以°F,而温度对背对约°F。这些条件导致了岩石的降雨:蒸发掉的岩石变成了液态的岩石雨，并在地球表面凝固。
