Do you remember the age of dinosaurs and how they became extinct? Well, if you don’t know then all credit goes to a large asteroid with a diameter of about 10-15 kilometers.

But that happened millions of years ago. Now it’s the era of humans. In our lifetime how often we see those types of large asteroids collide with Earth?

Luckily zero.

Still there are some, but not that large enough to eliminate whole human species from Earth.

Does that mean huge asteroids never came in our direction from that day?

NO

There’s someone who protects us from all these dangers. That someone is Jupiter.

Thanks to its huge size and gravity.

When huge asteroids enter our solar system, Jupiter’s gravity attracts some of those asteroids towards it and slings out most of them out of the solar system. So possibility of those types of asteroids collide with Earth is very rare with a probability of one in millions of years.

If there was no Jupiter, Earth was going to be the most massive object close to our Sun.

Now you can guess what would have happened because of that….

Also, you know, life can’t exist without water.

Some scientists believe Jupiter is the reason for the existence of water on Earth.

But how can that happen?

In the early ages of our solar system, the gas giant Jupiter attracted some icy asteroids inwards to the region where Earth was forming. It’s believed that these icy asteroids would have delivered enough ice to account for Earth’s oceans.

It’s kinda weird to imagine a planet which is responsible for keeping us safe from large asteroids, attracted asteroids towards us so that life on Earth will be possible.

So if there was no Jupiter, we probably wouldn’t be dead, because we’d never have lived in the first place.

It’s really amazing how lucky we are. Everything is in their perfect state and position to keep us safe.

That’s why we should be more excited about taking care of our own planet instead of staying over excited for colonizing Mars.
