what if all planets were earth sized

all planets size

Have you ever wondered what it would be like if every planet in our solar system were the same size as Earth? Well, let's take a look at this mind-blowing scenario and imagine what each planet would look like if it were the same size as our beloved blue planet, with Mars' barren red landscape suddenly turning into a lush green Oasis and the massive swirling gas giant appearing as a lush green oasis. The first planet on our list is Mercury, the smallest planet in our solar system, but forget about the moon for the time being. If Jupiter suddenly disappeared, how would it influence our solar system as a whole? Would we all perish? Buckle up and let's find out.

The first planet on our list is Mercury, the smallest planet in our solar system. However, instead of picturing Mercury's moon, imagine yourself on the surface of an intensely dynamic inferno with active volcanoes all around you and a massive blindingly bright Sun directly in front of you. What a nightmare, but let's examine these modifications carefully Along with the increase in mercury's size, its mass and gravity would also rise, which suggests that mercury might have more atmosphere Mercury has extremely high temperatures due to its thin atmosphere and near proximity to the Sun.

When the gravity is stronger, Mercury could have a denser atmosphere so the heat would be better distributed across the planet. The atmosphere isn't the only thing that could make Mercury hotter; if Mercury became larger, it would likely experience increased internal heating due to gravitational attraction. Mercury has an atmosphere, so during the day the temperatures there reach 800 degrees Fahrenheit and at night it becomes terrifyingly cold down to negative 290 degrees Fahrenheit.

It would be much more difficult to send our spacecraft there, so it is preferable for Mercury to remain as it is now, which is small, calm, and boring, basically the opposite of our next planet Venus. What would happen to Venus if it were Earth-sized? Nothing, so congratulations you've turned Mercury into Venus 2.0 for us. However, all these changes wouldn't be very pleasant.

Because of its brightness and visibility in the sky, Venus is frequently referred to as The Morning Star, but don't be deceived by its beauty. Unfortunately, you won't be planning any trips to this planet anytime soon because it is one of the most inhospitable places in our solar system. Its surface is hotter than a freshly baked pizza and is covered in dense sulfuric acid clouds that would disintegrate any human who tried to visit. Instead, let's move on to Mars, which unlike Venus might someday become our new home.

Imagine yourself standing on Mars' surface, gazing at a brilliant sunset while inhaling a cool breeze. You may also be surrounded by plants and animals, giving you the impression that you are on Earth. But how is that possible? A larger Mars would have a stronger magnetic field and gravity, which would result in a richer and denser atmosphere. It would likely contain a wider range of gases, including oxygen. Wouldn't that be cool? Also, a denser atmosphere would mean that it would the most significant modification.

However, it wouldn't be all fun and games because Mars would also have a volcanic personality. It is already geologically active, but now its internal heat and pressure would Skyrocket, meaning more frequent and more crazy volcanic eruptions. Imagine how exciting it would be to witness such eruptions. Mars actually has some frozen water at its poles and in subsurface reservoirs, but with a stronger gravitational pull it could potentially stabilise liquid water on its surface hooray. but now is the time to move on to the giant planets of our solar system, and if we're enlarging the planets before, it's time to squeeze them really, really hard. For example, if Jupiter were to shrink by 11 times, that would be a catastrophe. The first thing we would notice would be a change in gravity, and I say we'd notice because we would then be forced to move.

Because of Jupiter's tremendous gravity, which draws them all in and shields us, between 30 and 100 massive asteroids collide with it each year; however, now that our big protective brother has shrunk into a small baby, say hello to a number of asteroids.

Oh, and say goodbye to Jupiter. This planet is known for its thick, swirling atmosphere, but with a weaker gravitational pull, Jupiter would likely have a hard time holding on to it. Over time, Jupiter would slowly escape into space, leaving behind a thin atmosphere primarily made of nitrogen and oxygen.

The most notable difference would be The Disappearance of its famous rings, which are made up of tiny pieces of ice and rock and are a distinctive aspect of Saturn. We'll also have to say goodbye to the iconic appearance of another giant. but because of Earth's gravity, they would either land there or disperse into space bombers. Saturn is a gas giant like Jupiter; its atmosphere is primarily made of hydrogen and helium. If Saturn were the size of Earth, its gases would be compressed due to the increased gravity, making Saturn much denser. In theory, if Saturn were squeezed extremely hard, it might turn into a brown dwarf.

The weather on Saturn might also have changed, as all of its crazy storms, like the famous hexagonal storm at its North Pole, would have become weaker and calmer. The next giant is Uranus. Let's try to compress this portfella first. Surface gravity on Uranus would be much weaker than it is now. Its atmosphere might be thinner as well. It is a type of failed star that lacks the mass to sustain nuclear fusion but emits heat and light.

As you can see, gas giants don't easily go through all this shrinking, but one of them, the surprisingly small Neptune, might become much friendlier for starters. It would probably be a rocky planet with a tiny atmosphere, meaning no more gas giant but instead a planet. However, if it were the size of Earth, it might actually warm up a bit due to its reduced volume to surface area ratio. However, don't get too excited because it would still be significantly colder than The atmosphere of the original Neptune is so thick you can hardly see your hand in front of your face, and the surface pressure is approximately 100 times that of Earth's atmosphere. However, our new Neptune would be very different with a much thinner and less dense atmosphere; it would still have some methane, water, and ammonia in it, but nowhere near as much as before finally the temperature would be much higher.That is all there is to say about the changes to the globe; that is more like it.

But what would happen to the entire solar system if we shrunk all the planets? It's difficult to say, but it's obvious that their gravitational pull and orbits could change significantly. It's unlikely that any of them would have flown into space or collided with one another, but many of their orbits would likely become quite unstable and the number of asteroid collisions would have increased noticeably. Of course, all of this is just conjecture; it's not fact.
