右边的那个点，是太阳系中已知的最大的岩石。它比任何已知的小行星、月球和彗星核都要大。它比当地任何一颗岩石行星都要大。这块岩石非常大，它的重力使它变成了一个大球，在它的表面附近容纳了大量的气体。（在最近发现围绕其他恒星运行的大型致密行星之前，它曾是所有已知类型中最大的岩石。）1990年，旅行者1号宇宙飞船从太阳系外拍摄了这颗巨大的太空岩石的特色照片——著名的“淡蓝点”。今天，这颗岩石开始围绕其母恒星运行另一个轨道，大约是50亿次，每次旋转超过350次。祝地球上所有的居民新年快乐。

There, that dot on the right, that's the largest rock known in our Solar System. It is larger than every known asteroid, moon, and comet nucleus. It is larger than any other local rocky planet. This rock is so large its gravity makes it into a large ball that holds heavy gases near its surface. (It used to be the largest known rock of any type until the recent discoveries of large dense planets orbiting other stars.) The Voyager 1 spacecraft took the featured picture -- famously called Pale Blue Dot -- of this giant space rock in 1990 from the outer Solar System. Today, this rock starts another orbit around its parent star, for roughly the 5 billionth time, spinning over 350 times during each trip. Happy Gregorian Calendar New Year to all inhabitants of this rock we call Earth.
