What is the orbit plane of revolution =The three-dimensional sense is not very good How can there be an orbital plane for revolution? Isn't the orbit a curve
Simulation, you find a rope, one end tied with a key, swing it up, this time the key is a curve
But can you make it stick to the wall (vertical rotation) or the table (horizontal rotation) without touching the wall and the table? At this time, it means that the curve it takes is subordinate to the wall or the table. This surface is the track surface of the key rotation
What is the revolution of the earth
The earth revolution around sun is the earth revolution around sun in a certain orbit. Just like the earth's rotation has its unique regularity, because of the sun's gravitational field and rotation, The earth's revolution also has its own laws. These laws include the earth's orbit, the earth's orbital plane, the angle between the yellow and the red, the period of the earth's revolution, the speed of the earth's revolution and the effect of the earth's revolution
Let the earth's revolution period and orbit radius around the sun be t and R respectively, and the moon's revolution period and orbit radius around the earth be t and R respectively. Then the ratio of the mass of the sun to that of the earth can be obtained
When the earth revolves around the sun, we know the orbit radius and the revolution period, and we use gravity to provide centripetal force: gmmr2 = m · 4 π 2rt2m = 4 π 2r3gt2. When the moon revolves around the earth, we know the orbit radius and the revolution period, and we use gravity to provide centripetal force: GMM ′ R2 = m ′· 4 π 2rt2m = 4 π 2r3gt2, so the ratio of the mass of the sun to the mass of the earth is mm = r3t2r3t2
