Rotation of the Earth and the Sun
The Earth's rotation around itself is of course not the only movement in space. The Earth revolves around the Sun and its orbital speed around the Sun is about 107,000 km/h.
It takes the Earth about 365 days to revolve around the Sun, in an elliptical orbit. The distance between the Earth and the Sun - called an astronomical unit - is 149,597,870 kilometers, according to the International Astronomical Union.
The Earth travels a distance of about 940 million kilometers within one year. When dividing 940 million km by 24 hours, the result will be that the Earth is moving at a speed of 2.6 million km per day, or 107.226 km/hour.
?What is the speed of the sun and the galaxy
The sun and the galaxy also move, and the sun has its own orbit in the Milky Way, and is about 25,000 light-years away from the center of the galaxy, and at least 100,000 light-years away from the Milky Way. It is believed to be located about halfway from the center, according to Stanford University. It appears that the Sun and the Solar System are moving at a speed of 200 kilometers per second, or an average speed of 720,000 km/h). Even at this fast speed,
It would take the solar system about 230 million years to move along the length of the Milky Way.
The Milky Way Galaxy completes a full cycle every 225 million Earth years, and this period is called the galactic year. But that is not all, because the differential rotation may result in spiral arms at first, but over time these arms will overlap and wrap around each other, causing the structure to become distorted instead of being regular as it always is.
The bottom line is that everything in the universe is in motion.
?What would happen if the Earth stopped rotating
The force of Earth's gravity is very great compared to its rotation, and it reaches its strongest point, at the equator, which is why a person feels lighter at the equator compared to the north or south poles.
NASA says that the probability that the Earth will stop rotating is 0% within the next few billion years. However, if we imagine theoretically that the Earth suddenly stopped moving, the effect will be horrific, as the atmosphere will move at the original speed of the Earth’s rotation, which means that everything will be uprooted. Above the ground, whether buildings, people, trees or rocks.
