Sir Patrick Moore was a famous Earth astronomer.
In May 1997, Patrick Moore was interviewed by Eve Waugh on television with Professor Bernard Quatermass regarding the Mars 97 mission. (PROSE: The Dying Days)
He was mentioned (jokingly) by Rose Tyler when the Ninth Doctor asked her who she considered to be the ultimate expert in alien lifeforms. (TV: Aliens of London)
The Doctor apparently met him at some point in the past, referring to him as "a devil" with the ladies. He was one of many experts holding a conference over the Internet when the Atraxi were threatening to boil the Earth. The Eleventh Doctor, after providing proof that he was a genius, showed the assembled experts how to create a computer virus that would alert the Atraxi to the position of Prisoner Zero. (TV: The Eleventh Hour)
