Revolution
The earth orbits around the sun and the moon orbits around the earth, this is called revolution. Revolution length is 585 million miles. The earth takes 365 days to orbit around the sun once. The actual shape of the orbit is not circle but an oval-like shape, ellipse. The farthest distant point from sun is aphelion and the closet planet or point from sun is perihelion the reason why we have different temperature. The earth is tilted with 23.4 degrees. Earth Axis is an imagined line cross the globe. The equator is the division in middle of earth.
When we see stars in the sky moving, it is actually the earth spinning, we call the group of stars constellation. A constellation is a pattern formed by the stars in the night sky. Revolution is cause by gravity pulling the earth by the Sun; it is actually the earth falling. The earth is tilted, so the sunlight is not spread evenly through the earth. Revolution causes different seasons, like summer, winter, fall, spring. For example when the earth equator tilted to the south, southern side straightly faces the sun it is summer time in south. Same as when the earth revolves and the earth equator is tilted to the north; the northern side gets summer because the sun is directly straight facing north. Basically revolution means change to new.
However all the planets maintain balance and communicate. Revolution is really important in order to have different seasons, climate also moon phases. The earth axis and equator helps to have terms. Revolution help us to know more about the planet,and figure why we have different season and weather. Also change the way people believe,extend the horizon of science.
