Ok, by happenstance, I found it and learned how exploration work as well. I told myself it must be way out past Frigaha 6, so I flew 200,000 Ls away from the Frigaha star past Frigaha 6... and didnt find a thing (but an Adder selling beer... seriously!... space must be lonely for this guy). On my way back to the Frigaha star, I however happened to see from the corner of my eye, a cluster of 'things' moving. While I wasnt able to select/target them, I literally flew into it and crash/found Frigaha 9.
I repeated the process to found 7 and 8. I guess that's how exploration works with a basic sidewinder. Pretty cool. I even took down an Imperial clipper (with help of the Feds) and got an 86k bounty reward. Fun game.
Edit: In the future however, I'll buy the data
