First Check around the solar system for a fairly large planet (3^rd out from the sun) which looks roughly as shown.

Ok If you've found that you half way there. Now look for Great Britain (marked in Red (Labour Gov) on the map)

(If you are using GPS use:-

Lat 51 32.01 North - Long 0 47.31 East )

Thanks to RALPH COULSON for the coordinates

Now page down to next map
