What If Earth Was the Only Planet in the Solar System?

Imagine never being able to dream of landing on Mars or traveling to Saturn. Not because it’s impossible to get there, but because they didn’t exist. Because Earth was the only planet in our Solar System. The other eight planets in our Solar System aren’t just pretty to look at, or something we strive to travel to one day. Even though they’re billions of kilometers away, they’ve played an essential role in life here on Earth. So what would happen if they had never existed? Each planet in the solar system played a vital role in the development of Earth billions of years ago, and they continue playing a vital role in keeping Earth safe today. For example, take the placement of every single planet. They all have their own little space in the galaxy, and that’s not by accident. Our planets work together to keep each other in place. For example, if Mercury and Venus ceased to exist, Earth might drift closer to the Sun. And if Jupiter or Saturn disappeared, instead of going closer to the Sun, the Earth might drift further away from it. This would cause a number of issues for us Earthlings. Right now, we’re lucky enough
to live in what scientists call the “Goldilocks Zone.” They call it that because Earth sits in the range of orbits around the Sun that are just right to sustain life. If Earth were to move closer to the Sun, it would get a little bit hot. We might burn to a crisp. The farther away we get, the more the temperature would drop. Earth would be too cold to sustain life. . The position of Earth in our Solar System not only affects life, not only affects life, but everything that happens on our planet. but everything that happens on our planet. but everything that happens on our planet. It affects our seasons, the length of our days, and how long our year is. But unfortunately, the time we wake up will be the least of our worries. With Earth being the only planet in our Solar System, there’s no telling where it might end up. We could be all the way in the back, where Uranus and Neptune used to be, or somewhere right up front where Mercury once was. It’s safe to say that no matter where we end up, if it’s not the Goldilocks Zone, there’s a pretty good chance there
wouldn’t be any life here on Earth. If life did form somehow, it would definitely be aquatic. That’s because, without any other planets keeping us in check. Earth’s gravity would be severely different. When we say ‘no other planets’ we mean no moons either. The Moon’s gravitational pull is responsible for the tides here on Earth, without it, our waters would remain still. The oceans wouldn’t rise or fall, they would just stay where they were. So really, Earth as we know it wouldn’t exist if there were no other planets. There’s virtually no chance that
humanity would be living today, but what if, instead of the planets never
existing in the first place, one day they suddenly disappeared? Well, apart from Earth violently moving around, not knowing where to go, we’d also have another
huge issue to worry about. It’s clear that every planet is critical to life on Earth. If just one planet suddenly disappeared, a number of issues would go along with it. There are two planets that have a very special role in keeping Earth safe. Jupiter and Saturn. That’s because while Earth is hanging out, thriving with life, Jupiter and Saturn are getting beat up by millions of asteroids. Flying throughout the solar
system, there are hundreds of millions of asteroids that are trying to kill Earth. Luckily, we hardly see any of these, and that’s thanks to Jupiter and Saturn. Because of their enormous size and gravity, they do an excellent job of pulling asteroids into them so that they never make it to Earth. With these planets gone, Earth would be bombarded by asteroids. Not good. In case you’ve forgotten, a single asteroid hit Earth millions of years ago, wiping out the entire dinosaur population. So this would end up being pretty bad. Earth would soon be covered with massive craters, and once again, life would cease to exist. Luckily, you won’t have to worry about any of this. You can rest easy knowing that Earth sits comfortably in this perfect little spot in the Universe, where we can all live and thrive. Another thing you don’t need to worry about is what would happen if the Earth lost oxygen for five seconds. But it is fun to think about it anyway so, we’ll leave that story for another WHAT IF.
