Every planet has their own characteristic and nature just like humans have. Planets have to take one of the 12 signs in your birth chart. Among those twelve houses each planet will have a particular house as its favorite place.
This place/house if occupied by the planet, its exalted or happy. Similarly there are houses which a planet finds difficult to live in or is not happy about. In such houses planet is known as debilitated.
