Rotation of The Sun, The Earth and The Moon

太阳、地球与月球 The Sun , The Earth and The Moon

太阳

太阳或日是位于太阳系中心的恒星，它几乎是热等离子体与磁场交织著的一个理想球体。其直径大约是1,392,000(1.392×10⁶)公里，相当于地球直径的109倍。

The Sun is the star at the center of the Solar System. It is almost perfectly spherical and consists of hot plasma interwoven with magnetic fields. It has a diameter of about 1,392,684 km, about 109 times that of Earth.

地球

地球是太阳系八大行星之一，按离太阳由近及远的次序排列为第三颗。地球是太阳系的第三颗行星，也是太阳系中直径、质量和密度最大的类地行星。住在地球上的人类又常称呼地球为世界。地球是上百万种生物的家园，包括人类。地球是目前人类所知宇宙中唯一存在生命的天体。

Earth is the third planet from the Sun, and the densest and fifth-largest of the eight planets in the Solar System. The planet is home to millions of species of life, including humans.Both the mineral resources of the planet and the products of the biosphere contribute resources that are used to support a global human population.

月球

月球，俗称月亮，古时又称太阴、玄兔，是地球唯一的天然卫星，并且是太阳系中第五大的卫星。月球的直径是地球的四分之一，质量是地球的1/81。

The Moon is the only natural satellite of the Earth, and the fifth largest satellite in the Solar System. It is the largest natural satellite of a planet in the Solar System relative to the size of its primary,having 27% the diameter and 60% the density of Earth, resulting in ¹⁄₈₁ its mass. 

Bersenam untuk sihat ！（Let's do exercise 多多运动吧！ ）

Bersenam dan aktiviti fizikal juga memainkan peranan penting dalam memperbaiki status kesihatan, meningkatkan kecergasan serta membantu mengawal dan melawan penyakit.

Mechanism of The Seasons 四季的形成

A season is a period of the year that is distinguished by special climate conditions. 

The four seasons—spring,summer, fall, and winter—follow one another regularly. 

Each has its own light, temperature, and weather patterns that repeat yearly.

Seasons occur because Earth is tilted on its axis relative to the orbital plane, the invisible, flat disc where most objects in the solar system orbit the sun. Earth’s axis is an invisible line that runs through its center, from pole to pole. Earth rotates around its axis.

Matahari - The Sun

The sun is a star, a hot ball of glowing gases at the heart of our solar system. Its influence extends far beyond the orbits of distant Neptune and Pluto. Without the sun's intense energy and heat, there would be no life on Earth. And though it is special to us, there are billions of stars like our sun scattered across the Milky Way galaxy.

Matahari adalah merupakan pusat bagi sistem suria (centre of the solar system).Matahari (Sun) adalah sejenis bintang (star), dan ia adalah satu-satunya objek dalam sistem suria/solar yang boleh memancarkan cahaya (radiate light) dan menjana tenaga sendiri. Matahari juga adalah bintang yang paling hampir dengan Bumi (Earth), iaitu kira-kira 150 juta km daripada Bumi.
