targeting the next unexplored planet in a system

[Jibsman]

This has probably been answered many times, but I can't seem to formulate a search that gives me the answer 

I'm exploring a system, starting with the sun, then the next unexplored planet in the list. What command do I give VoiceAttack to target the next unexplored planet in a system?

Thanks,
Jibs
