"29,029 feet."
Believable, reasonable, sensible. I'm glad you're in the solar system, Earth. What about you, Mars? How high is your tallest mountain?
"81,840 feet."
OK, Mars -- easy does it. That isn't even a cool thing to say, Mars. Just because that is a horizon-changing mountain doesn't make it the least bit desirable. I will definitely not be staking my claim on anything close to Olympus Mons when we travel to Mars to begin terraformation and rebuild civilization on a new planet. No. No thank you. Not that sweet. I'd rather bathe in brackish water than watch a Martian sunset with Olympus Mons in the way.
