Travel

Fuel: A "unit" of fuel is defined as the amount of fuel (from a fusion fuel cell) needed to accelerate 1 ton of mass (weighed in 1.0 Gs) to 100,000km/h. So, to accelerate a 50-ton ship to 100,000km/h (standard cruising speed for most interplanetary travel) would require 50 fuel units. One fuel unit costs one credit.

Speed:
Atmospheric speeds are defined as travel at 15,000 km/h or lower.

Coastal speeds are defined as travel at 15,000 to 250,000 km/h.

Deep speeds are defined as speeds over 250,000km/h. Only one is on record with top speeds above 500,000 km/h, an experimental manned craft built by the famed pirate Archibald the Wayfarer. It had a crew of two (pilot and a robotic navigator) and completed one journey at approximately 700,000 km/h during a daring getaway.

Distance:
The megacorp planets and aeneas are all between 25 and 30 million km from each other. Briseis and chryseis are only 10 million miles from each other, but about 40 million km from Aeneas (the next closest planet). Nestor, the next most distant planet from the sun after the megacorp planets, is about 60 million km from Diomedes. Distances increase steeply from there. The distance between Castor and Pollux is about 3 billion Km, a frighteningly close distance between two star systems that has baffled astronomers for generations.
