What's up with planet Aequitas?
Solution 1:
Apparently it isn't important at all, and this is a bug many users are reporting.
Solution 2:
Aequitas is a bug, However its also a side N7 Mission from Mass Effect 2 where you investigate reaper disturbances in a mine only to be overrun by husks.. You then detonate the mine to destroy the reaper artifacts and husks.
