British astronaut Tim Peake gestures as his space suit is tested at the Russian-leased Baikonur cosmodrome, prior to blasting off to the ISS, on December 15, 2015.

Tim Peake, the first British astronaut on the International Space Station, dialled a wrong number after trying to phone home, asking a woman "is this planet Earth?".

"I'd like to apologise to the lady I just called by mistake saying 'Hello, is this planet Earth?' -- not a prank call... just a wrong number!" he tweeted late Thursday.

Peake, 43, became the first British astronaut to travel to the space station after blasting off from the Moscow-operated Baikonur cosmodrome in Kazakhstan earlier this month for a six-month mission.
