🌜The Moon🌛
✨The Moon is 384, 400 km from the Earth and More than 25% of Earth's diameter.
✨Once every month, the Moon orbits the Earth. Each orbit takes 27.3 days. It spins around once on its axis in exactly the same time, so only one side of the Moon's surface can be seen.
✨The moon is the brightest object in the night sky, but it does not give out any light itself. It shines only because it surface reflects sunlight.
✨One half of the Moon is always lit by the sun, but as it travels round the Earth, different amount of sunlit side can be seen. This is why the Moons seems to charge shape. These are called the phases of the Moon.
✨A lunar month is the time between one Full Moon and the next. This is slightly longer than the time the moon takes to orbit the Earth because the Earth is also moving.
✨The Moon has no atmosphere and its surface is simply dust, pitted with craters created by meteorites smashing into it early in its history.
✨On the Moon's surface are large, dark patches called seas because that is what people once people once believed they were. They are actually lava flows from ancient volcanoes.
✨One side of the moon is always turned away from the Earth and is called its far side. This is because the moon spins round on its axis at exactly the same time that it orbit the Earth.
✨Unlike the Earth's surface, which changes by the hour, the Moon's dusty, crater pitted surface has remained much the same for billions of years. The only change happens when the meteorite smashes into it and creates a new crater.

🌘Eclipse🌒
✨When one space object, such as the Moon, blocks out the light from another, such as the Sun, an eclipse occurs.
✨A lunar eclipse is when the Moon travels behinds the Earth, and into the Earth's(Earth is between the Moon and the Sun).
✨Lunar eclipses happen about once or twice a year and lasts only a few hours.
In a total lunar eclipse, the Moon turns rust-red.
✨Lunar eclipse can be seen from anywhere on the half of the Earth facing the Moon.
✨A Solar eclipse is when the Moon comes between the Sun and the Earth, casting a shadow up to 270 km wide onto the Earth's surface.
✨In a total eclipse of the Sun, the Moon passes directly in front of the Sun, completely covering it so that only its corona can be seen.
✨There are at least two solar eclipses every year, but they are only visible from a narrow strip of the world.
✨Totality is when the Moon blocks out the face of the Sun completely. It only lasts for a few minutes.
✨Solar eclipse are possible because the Moon is 400 times smaller than the Sun, and is also 400 times closer to the Earth.This means the Sun and the Moon appear to be the same size in the sky.
✨During a total Solar eclipse of the sun, the moon blocks everything except the sun's corona.
