The astronomer, who has hosted The Sky At Night on the BBC since its first episode in 1957, revealed he aims to continue doing so when he turns 90 in March 2013.
"I've no plans to stop," he said at the launch of his new book Cosmic Tourist with Queen's Brian May and scientist Chris Lintott.
When asked if he will start just making guest appearances on the show, Moore said: "No, I'm not planning to do that."
Moore is a former president of the British Astronomical Association and co-founded the Society for Popular Astronomy. He has also written over 70 books on the subject, while also being an accomplished xylophone and piano player.
