It is not every day that you get a call from the International Space Station asking “Hello, is this planet Earth?” An unsuspecting woman experienced exactly this on Christmas when British astronaut Tim Peake mistakenly called the wrong number from the ISS.

The astronaut later apologised to the lady for his mistake and assured her it was not a prank call and that he was trying to speak to someone on earth from the International Space Station.

Tim Peake divulged this on microblogging site Twitter.

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!
