British astronaut Tim Peake gave an unsuspecting woman a shock after dialling the wrong number and saying: “Hello, is this planet Earth?”

After the gaffe he tweeted: “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!”
