Re: Gravity well problem
You could escape it's gravity well using chemical rocket engines easily enough.
Yep. For a planet with 1.4x Earth's radius and 7 times Earth's mass, you're looking at an escape velocity of 25km/s, give or take. 3.5x Earth's surface gravity will impose a modest increase in engine weight and a larger penalty in fuel for ~3-4km/s in gravity losses, versus Earth's 1km/s. That is feasible with chemical rockets, just challenging for any payload larger than one seat.
Locals are encouraged to review the work of Dyson and his Orion launch system.
