What if the Earth was 10 times bigger?

If the hypothetical super-Earth were even bigger, say, 10 times its current mass, dramatic changes could start happening in Earth’s interior. The iron core and liquid mantle would also be 10 times larger, and with more gravity acting on a larger mass, the pressure beneath Earth’s surface would increase.

What if Earth became bigger?

Our weight would increase. If Earth’s diameter doubled but density was similar to the old Earth, the planet’s mass would go up and gravity would be twice as strong. That would instantly make your weight twice as much as it was before. It’ll be especially bad news for those who use the Imperial system.

What will be the duration of a day if the volume of Earth shrinks to 1 64 th of its initial volume mass remaining unchanged?

What will be the duration of the day if the earth suddenly shrinks to 1/64th of its original volume but mass remains unchanged? If the volume of earth suddenly shrinks to 1/64th of its original volume then the radius of the earth will decrease to 1/4th of its original radius. So, duration of the day will be 1.5 hrs.

What if the sun gets bigger?

The sun is a star, and when a star explodes it’s called a supernova. If the sun suddenly exploded like this, the whole solar system would be destroyed. You don’t have to worry though – only stars ten times the size of our sun, or bigger, can explode like this. Our sun will end its life in a different way.

What if the sun was twice as big?

The gravity of the sun has doubled, meaning the pull on Earth is 4 times stronger. Earth’s orbital velocity would slow down greatly as the direction of the Earth’s motion points to the star. Earth would be brought close to the star and would be additionally scorched at this closer distance.

What will be the duration of a day if Earth suddenly shrinks to 1 27 parts of 8 times of it’s volume without changing its mass?

Earth would spin 9 times faster, so our day would be only 2.66 hours long.

What will be the effect on the duration of the day if the earth suddenly contracts?

So, for an Earth that is contracted to half its present size with mass constant, the duration of a day will be just 6hrs.

What if Sun exploded?

But the good news is that, if the Sun were to explode tomorrow, the resulting shockwave wouldn’t be strong enough to destroy the whole Earth. And without the Sun’s mass keeping us in orbit, Earth would likely start floating off into in space while its remaining inhabitants desperately struggle to stay alive.
