What would happen to the gravitational pull between Earth and the moon if the moon were twice as large Explain your answer?
The moon also has a tidal effect on Earth’s land, Comins said. If the moon were suddenly twice as close to Earth, the effect would be like hitting a gong with a mallet, Comins said: Waves of energy would reverberate through the planet due to the sudden increased strength of the moon’s gravitational pull.
What would happen if the moon was twice as far from the Earth?
If the Moon were twice as far from the Earth as it is currently, there would be no total solar eclipses any more. Currently the relative sizes and distances of the Moon and the Sun means that total solar eclipses can happen.
What would happen to the force of gravity between the Earth and the Moon if the Moon was twice as close to the Earth than now?
Right now, with the Moon very slowly moving away from us, a day on Earth actually extends by 15 millionths of a second every year. But, if the Moon were suddenly twice as close, the new-found gravitational force would cause the Earth to spin faster.
Was the Moon closer to Earth in the past?
The moon used to be closer. When it first formed, about 4.5 billion years ago, molded out of rocky debris that had been floating around Earth, the moon orbited 10 times nearer to the planet than it does today. The debris, scientists believe, had come from a collision between Earth and a mysterious Mars-sized object.
What would happen to Earth if there was no moon?
Without a moon, Earth would spin faster. Our day would be shorter. Why? It’s because, billions of years ago when Earth was young, our planet spun around on its axis much faster. Our world’s cycle of day and night was less than 10 hours long.
What would it be like to live on the Moon?
If you lived on the moon, you’d have to give up lots of things you take for granted on Earth. The feeling of your feet planted firmly on the ground. Your ability to breathe outside without a helmet. And your night-sky view.
Why does the Moon appear to rise and set?
The moon appears to rise and set as seen from Earth not because of the moon’s motion – but because Earth spins once a day on its axis. Because one side of the moon always faces us, from most places on the moon, Earth doesn’t appear to rise or set. Instead, from a given point on the moon’s near side, you’d always see Earth hanging in your sky.
What would the earth look like if the Moon was bigger?
The Earth would also look much bigger than the moon does to us. (The Earth is about four times larger than the moon, in diameter.) And from the perspective of the moon, Earth would also always appear to be in a fixed location.
