The earth and the sun would rotate. The Earth had rotation and revolution. The Earth's rotation was a rotation around its axis of rotation. The direction was from west to east. It was counterclockwise when viewed from the North Pole and clockwise when viewed from the South Pole. The period was a sidereal day, about 23:56:4. Its angular velocity was about 15°/h (equal except for the poles), and its linear velocity decreased from the equator to the poles. The earth revolved around the sun according to a certain orbit. The orbit was an oval orbit that was close to a perfect circle. The direction was from west to east. The revolution period was 365 days, 5 hours, 48 minutes and 46 seconds. During the revolution, the earth's axis was tilted and the direction remained unchanged. Due to the different solar heat obtained at different latitudes during the revolution of the earth, the four seasons changed. The sun also rotated and revolved. The sun's rotation could be confirmed by the movement of sunspots and other active objects on the sun's surface or the Doppler-effect of the spectral lines on the east and west edges of the sun. Its rotation direction was the same as that of the Earth, but because the sun was a balloon, the rotation period of different parts was different. For example, the rotation period at the equator was about 27 days, 6 hours and 36 minutes. The higher the latitude, the slower the rotation. The sun's revolution was a movement around the center of mass of the Milky Way, the galactic center. It was located in the Orion spiral arm of the Milky Way, 25000 to 28000 light years away from the center of the galaxy. The revolution speed was about 220 kilometers per second. The orbit was an oval with a very small eccentricity. The solar system needed about 250 million years to orbit around the Milky Way.
