At what speed does Earth rotate?

roughly 1,000 miles per hour

Can we live without moon?

Without a moon the tilt of our earth’s axis would vary over time. This could create some very wild weather. Right now, thanks to our moon, our axis stays tilted at twenty-three point five degrees. But without the moon the earth might tilt too far over or hardly tilt at all leading to no seasons or even extreme seasons.

Would humans die if there was no moon?

The moon holds a significant relationship with the Earth: if there were no moon, our daily lives as humans would significantly change. Just as the Earth exerts a gravitational pull, the moon also exerts a gravitational pull on the Earth. The moon pulls on the Earth and slows down the Earth’s rotation.

What would happen if the moon hit the sun?

We would lose all tides on the Earth, as these are governed by the gravitational force of the Moon. The Sun would also not be too happy I would imagine, but it should not have too dramatic an effect on something as big as that. The sun weighs 100,000,000 times more than the moon.

What would happen if everyone on Earth jumped at the same time?

The ground would begin to shake, and if the jump happened near the coast, it could trigger a tsunami with 100-feet-tall waves. The shaking could also lead to an earthquake falling in the 4-8 magnitude range.

What would happen if we nuked the moon?

The explosion would also likely create a shotgun-like blast of moon debris, as lower gravity makes it easier for moon rocks and dust to easily escape the moon’s gravity. This would be ejected into space, but also strike Earth, creating micrometeor showers visible in the night sky.

Do asteroids ever hit the sun?

No asteroids have ever been observed to hit the Sun, but that doesn’t mean that they don’t! Asteroids are normally content to stay in the asteroid belt between Mars and Jupiter, but occasionally something nudges them out of their original orbits, and they come careening into the inner solar system.

What happens if a comet hits earth?

If the comet is 10 kilometers across or larger (that is, if the impact carries an energy of more than about 100 million megatons), the resulting global environmental damage will be so extensive that it will lead to a mass extinction, in which most life forms die.
