is there's probably Jupiters on the outside of the solar system.
They come too close to each other.
They're kind of wrestling almost.
They kind of excite each other.
One of them gets kicked out in a random direction.
And it can get flung into a highly eccentric orbit.
And a highly eccentric orbit over time will circularize.
So it doesn't want to stay on an eccentric orbit.
It wants to turn into a circle through the tidal interactions with the star.
So these things probably circularize really close onto their stars.
And it happens about 1% of star systems.
But it's an example of how diverse things are.
Another example is mini-Neptunes.
You ever heard of those planets?
So mini-Neptunes are these planets which are in between the size of the Earth and Neptune.
Neptune's about four times bigger than the Earth.
