There are dozens of undiscovered worlds really close to civilised space, and still a few Earthlikes kicking around. I found two in one system, one Earthlike, one terraforming candidate, around 200Ly from Kumbaya (gotta love that system name!) On the return (about 450Ly trip, so only about 5 screens worth of stuff to turn in) I came across several systems, one so close to Kumbaya that I couldn't sell the data there.
My strategy was to move "up" from Shinrarta and then to move north-west for a bit. When I saw other CMDR names I moved south a couple of jumps (40Ly) and then back to north-west. I ended up about 330Ly from Kumbaya. Moved "down" on economy until I started to see a few discovered system. Then I moved to faster jumps. 3M of exploration data, and a long list of "first discovered by..." Interesting trip. My faves are the huge gas giants.
