How to leave your world for free
"For example, maybe there’s a solar system out there where it isn’t small, rocky planets that fill up the inner orbits, but a mix of Earth-like, rocky worlds and also gas giants, some of which are even closer to us than our closest planet, Venus, when it reaches perigee. It might seem like a big deal that Venus achieves a minimum distance from Earth of only 38 million km, the smallest distance of any planet, but what if it weren’t a rocky world like ours, but a gas giant instead? And what if it weren’t 38 million km away, but a much smaller number?
Do you wonder what that might look like?”
