Mercury is not well seen from either the United Kingdom or North America but Australia will have a clear view. However, observers across the world with a telescope or binoculars should easily be able to see Uranus as a pale greenish-blue dot close to the Moon. The United Kingdom will be in the best position as the pair are at their closest in the early hours of the morning for that locale.
