ELI5: How do the planets in our solar system stay distant from eachother if the reason they're in the solar system is by the suns gravitational pull?

Shouldn't they just all pull each other in and form a clusterfuck of a planet or something along the lines?

They're not free to fall inwards because they are in orbit.

Imagine you throw a ball. It lands some way away. Ignoring atmosphere dragging at it, the harder you throw it, the further it goes, yes?

Now imagine throwing it so hard that it goes half way round the world before landing? With me so far? Now imagine throwing it so it comes all the way round and hits you on the back of the head. Because there's no atmosphere to pull at it, it's travelling at the same speed as when you threw it - so provided you duck, there's no difference between the first trip round the world and the next and the next and the next. Provided no one stands up, it'll carry on going round the world, falling yes, but falling at the same speed as the ground is curving away.

The planets are doing that - they're falling round the sun, but going sideways as well, so much sideways that they end up back where they started from a year later (in the case of the Earth) a couple of years for Mars and so on.
