Asimov’s Kalgash: a planet in permanent daytime (for real this time!)
Let’s find out what it takes to build a system in which a planet remains in perpetual daylight, except for once every few thousand years….

The asteroid belt: a cosmic refugee camp?
The asteroids may be cosmic refugees, ejected from their homes to wander the Solar System, eventually settling in the asteroid belt.
Where did Earth’s (and the asteroid belt’s) water come from?
Imagine a dry Earth. No waterfalls. No oceans. No beer (or people to drink it). A sad place. Water is pretty important stuff. In this post we will go deep into how Earth got its water (much deeper than in this post from a while back). And since it’s connected with how Earth formed, our…

I always thought that only 2 or 3 planets could share the same orbit. I was wrong. And it changes everything (for a super-advanced civilization, anyway).
The Ultimate Retrograde Solar System
I stumbled upon a simple way to tighten up the Ultimate Solar System. And by stumbled upon, I mean I discovered that someone else had figured it out. And I took it.
