Ugh, I can't stop thinking about this.

I was reading The Promise of Space by Arthur C. Clarke last night. It is a masterful work of non-fiction, and I highly recommend it. Anyway, I was reading a chapter about orbiting different planets, and there was a chart of every planet's escape and orbital velocities.

The sun's orbital velocity is 980,000 mph.

Just think about that for a minute.

A million miles per hour just to establish orbit around the sun.

A million miles per hour!
