Welcome back to our next blog post on astronomy!
The moon’s formation is theorized by two theories. The simultaneous formation theory said that the Earth and the Moon formed at the same time, around 4.6 billion years ago. The impact theory states an object collided with the Earth breaking the Earth apart into the planet and the moon.
The moon has two sides, a dark and a light, the difference is which side the light is shining upon. The farther side of the moon is not visible from the Earth due to synchronous rotation; the same rotation period of the Earth is the same as the Moon orbits the Earth.
The moon’s orbit around the Earth as the Earth orbits around the sun results in several different phases on the moon on where light shines. The moon orbits Earth counterclockwise.
There are also certain times where the sun, the Earth, and the moon are aligned perfectly to form eclipses: lunar and solar.
The sun has a very complex structure:
The sun’s heat is formed by nuclear fusion where Hydrogen atoms combine to form Helium, and this takes place at the sun’s core.
Energy comes as waves traveling through space from the sun in multiple types of rays: gamma, X, UV, Visible, Infrared, and Radio.
