Gravity

“Yes. This is Earth gravity.”

He steps side to side, rolling his geodesic dome one face back and forth. “Not much gravity. What is value, question?”

“Nine point eight meters per second per second.”

“Not much gravity,” he repeats. “Erid gravity is 20.48.”

“That’s a lot of gravity,” I say. But that’s to be expected. He’d told me all about Erid before, including its mass and diameter. I knew their surface gravity had to be roughly double Earth’s. Nice to have my calculations verified, though.
