Thank you Saturn.

Just when it seemed that Jupiter was destined to sweep the inner solar system totally clean – with no chance of the Earth ever forming – and end up as a close companion to the sun, another planet leapt to the rescue.

O-H!

I thought it was Neptune that saved our ass.

Neptune too far away and 'small' to impact Jupiter.

Saturn appr. 3X smaller than Jupiter (which is HUGE in and of itself). It was also migrating towards the inner solar system along with Jupiter. Resonance is a term used (which is caused by Jupiter rotating 3X around the Sun and Saturn 2X, at nearly exact rates), and such the gravitational dance going on between Saturn and Jupiter. Each time their paths crossed, Saturn tugged on Jupiter - which can be visualized as pushing a little on a person in a swing. And regular intervals over time, the motion causes the person on swing to go higher and higher up.

The true and only heavenly body that saves ass is Titan-Uranus.

Neptune's effects on the Kuiper Belt.

Studying the Kuiper Belt has taught us that Neptune formed much closer to the sun than where it is today, and it migrated outward. Computer simulations have shown us that the KBOs we see today were shoved onto those orbits as Neptune moved.

Why Uranus is a cold place.

Uranus is the only planet that is really in thermal equilibrium with the sun and there are two options as to why its surface appears cold. Firstly it could just actually be that Uranus is hot in its interior, but this heat is trapped. That means it can't cool down so it's hot inside but cold outside.

Alternatively, it may be that it just managed to lose its primordial heat, for example, via a giant impact or another unknown process. So the short answer is we don't really know why it's cold and this is one of the biggest mysteries surrounding Uranus.

Nope it was Uranus!!!

It was planet Krypton that saved earth.

Just read when you have the time. Hint hint... Exponential time can go back indefinitely...before the Big Bang.

Very interesting read..

A lot of people spend time wondering how it happened. I spend most of mine wondering why. Why is there something rather than nothing?
