Apparently the ΔV requirements for an interplanetary mission between Kepler-62e and Kepler-62f is ~2-3x that of the equivalent between 🜨 and . Life on a super earth orbiting a K-dwarf is hard.
Messed up my calculations slightly, but the overall conclusions are still accurate. Surprisingly, scaling ☉'s mass up or down by a factor of 2 has little effect on the cost of transfer orbits between 🜨 and . At least if their orbits are also proportionally scaled so that their respective insolations are unchanged.
