Rahu and Ketu can rule houses from the Kendra group (houses 1, 4, 7, 10).
When diagnosing which planet rules the house under examination, you can check where it is located in the birth chart, i.e., in which house the lord of the examined house is. If there are other planets next to the ruling planet, they will affect the rulers, and it may change the data written below, for better or worse.
