Other significant space-related queries include: Could The Sun Rotate Around The Earth?

Since we are on Earth, the Sun is the true center of the Solar System, but it is not the center of the Solar System with respect to Jupiter. The Sun is in a region of space called the Berry Centre, which is usually closest to the object with the greatest mass.

Since Jupiter is 318 times larger than Earth, where the Berry Centre is located, the equilibrium is different. The planets actually rotate around their Common Centre of Mass rather than the Sun.

To balance a pencil on the tip of your finger, you would need to

It's simple to assume that everything balances that way, especially in outer space, but try balancing a hammer on the tip of your toe; you'll likely leave this place with a broken toe because the true Berry Centre is closer to the hammerhead than the actual Centre where you'd grip it. Place the pencil exactly in the center to prevent it from tipping on either side. The Berry Centre of the Earth and the Sun is similar to a hammer in that the center of mass is generally in the middle of the item.

The other planets in our solar system must rotate around us as well because, realistically if the sun were to revolve around Earth, our tiny blue planet would have to be at least as large as the sun. However, back in the day, bright minds believed that everything in the universe revolved around the earth. This idea was known as the geocentric model, and it made sense to them because it appeared as though everything above us was spinning around.

In ancient Greece and the Middle Ages, the big brains used the geocentric model to study space. It wasn't until the 16th century that that model changed. At that time, they couldn't even imagine that everything revolved around the Sun and they didn't have the knowledge to support any of this. The Sun and the Moon played important roles in human history, and we didn't feel insignificant in the universe until much later.

Since the Earth is too small to serve as the center of the solar system under the necessary conditions, life would have developed differently and humans would likely be less reliant on oxygen. Whales and dolphins, for example, can go for hours without food.

Even though there are trillions of trees all over the world, the humans of the sun-sized Earth would have specialized lungs and wouldn't need to constantly be taking in air, which means that plant life would be restricted with only a few shrubs here and there. However, the main source of oxygen production is the algae in the ocean due to the vast amount of ocean and sea surface area the algae sitting on top are pumping out the air we breathe oxygen.

The sun is currently just big enough to provide us with what we need, but if the Earth were that big and the sun was another celestial body radiating heat, we'd always feel like we were inside a microwave. Days and nights would be different, and not much precipitation would happen with so much heat produced in the core. Earthquakes and other natural disasters would also be more common.

Living close to mountains could save you, though they would still be a part of the core and would be preferable to staying on the ground. Some mountain peaks might even be 100 times higher than Mount Everest, and canyons might be so deep that the Mariana Trench would feel like it was just about to rupture. Animals would also behave and look differently, and cold-blooded creatures would have to soak in water.

Birds can fly hundreds of miles during migration season, so we might see some sleek-looking birds speeding through the air. However, because gravity would be so strong on the colossal-sized Earth, flying animals would need thinner bones and a thinner core just to take flight. The real survivors would be the microorganisms they can live in. Animals would have to migrate to find water in distant lands.

The Earth rotates most quickly at its equator, so if all the planets and the Sun revolved around it, our rotation wouldn't be as significant. Additionally, new weather patterns wouldn't be good for crops, and humans would have evolved differently from how they are now. They would likely be shorter and stockier because of how strongly gravity pulls on them, and due to the extreme heat, they would likely live in caves all over the planet.

The strongest ones would have relocated to the highlands, and although our evolutionary history would likely be the same, some physical characteristics would alter. To fight this, our pigment might have a different appearance.

Heat It's possible that if we had larger ears than we do now for the latter reason, we would be much stronger than we are and our bones would be thick and difficult to break Gravity is one of the key components to developing our bone structure. The desert fox has large ears for hearing out predators and for cooling itself down in the scorching desert heat.
