Woman Wept

Woman Wept was a planet which continental land mass is shaped like a lamenting woman. The entire ocean, including waves hundreds of feet high, froze in an instant by means of some undisclosed disaster. The Doctor and Rose Tyler visited Woman Wept together, a visit which Rose later recounted to Mickey Smith. (DW: Boom Town)

Woman Wept was stolen by Davros and the Daleks, and placed it in the Medusa Cascade. This may have been the cause behind the sudden freezing of its ocean. When the Doctor and his companions defeated the Daleks, he returned the planet to its rightful place in the galaxy. (DW: The Stolen Earth / Journey's End)
