There are more planets than stars in our galaxy. The current count orbiting our star: eight.

The inner, rocky planets are Mercury, Venus, Earth, and Mars. The outer planets are gas giants Jupiter and Saturn and ice giants Uranus and Neptune.

Beyond Neptune, a newer class of smaller worlds called dwarf planets reign, including longtime favorite Pluto. Thousands more planets have been discovered beyond our solar system. Scientists call them exoplanets (exo means "from outside").

Chinese translation:

在我们的星系中,行星比恒星多。 目前围绕我们的恒星运行的数量为:八。

内部的岩石行星是水星、金星、地球和火星。外行星是气态巨行星木星和土星以及冰巨星天王星和海王星。

除了海王星,还有一类新的小行星,称为矮行星,其中包括长期以来最受欢迎的冥王星。 在我们的太阳系之外还发现了数千颗行星。 科学家称它们为系外行星(exo 的意思是“来自外部”)。
