In the original Jurassic Park novel by Michael Crichton, one of the animals they’ve cloned are these giant dragonflies. Its only one line in the book (Tim, one if the kids, sees one fly by and recalls reading about them) but it caught my attention as just straight impossible. I remember thinking, “Unless you’re somehow controlling the oxygen level of the air around this entire island, there’s no way that bug can’t breathe.”

What? Not it’s not. Where did you get this number?

It’s more like 6.7 AU. Source

In other words somewhere between Jupiter and Saturn in terms of distance to the sun.

Well, a billion kilometers is almost 7 times the mean distance between the earth and the sun. Asteroids pass in that distance all the time. We’re currently closer to Ceres (the dwarf planet) than that and its on the other side of the sun from us.

And how much gasoline are you refining in your backyard on those cloudy days?
