The Planets of our Solar System

Let's sing and learn :)

Let's learn some constellation in the sky :)

月食 Lunar eclipse

月食或月蚀，是一种当月球运行进入地球的阴影（本影部份）时，原本可被太阳光照亮的部份，有部份或全部不能被直射阳光照亮，使得位于地球的观测者无法看到普通的月相的天文现象。月食发生时，太阳、地球、月球恰好或几乎在同一条直线上，因此月食必定发生在满月的晚上（农历十五、十六、或十七），如《说文》所说“日蚀则朔，月蚀则望”。

A lunar eclipse occurs when the Moon passes directly behind the Earth into its umbra (shadow). This can occur only when the Sun, Earth, and Moon are aligned (in "syzygy") exactly, or very closely so, with the Earth in the middle. Hence, a lunar eclipse can only occur the night of a full moon. A lunar eclipse lasts for a few hours, whereas a total solar eclipse lasts for only a few minutes at any given place, due to the smaller size of the moon's shadow. 

地球自转形成白天与黑夜 Day and Night

地球自转是地球的一种重要运动形式，地球绕自转轴自西向东的转动，从北极点上空看呈逆时针旋转，从南极点上空看呈顺时针旋转。地球自转一周的时间是1日。
白天和黑夜，亦可代指事物两个相反的方向。昼夜由自转产生，谓之“太阳日”，但昼夜的长度并非等于自转周期，因为当地球自转一周后，同时进行了公转，公转使地球对于太阳的相对角度发生变化，而昼夜是以太阳照在地球上的范围来看的，所以一昼夜比自转周期多3分56秒。当地球自转时，面向太阳之地面为“昼”，背向太阳之地面则为“夜”。

Earth's rotation is the rotation of the solid Earth around its own axis. The Earth rotates towards the east. As viewed from the North StarPolaris, the Earth turns counter-clockwise.
The Earth rotates around once in 24 hours - that's a rate of 1000 miles per hour!. The time it takes for the Earth to rotate completely around once is what we call a day. It's Earth's rotation that gives us night and day.
