Moore on Mercury : The Planet and the Missions
Bok av Patrick. Moore
In his inimitable, easy-going style, Patrick Moore describes Mercury. He writes of the professional astronomers who have observed it over the centuries, amateur observations, and the past, present and future space missions to this extraordinary world. In doing so he has written the most up-to-date book about Mercury for amateur astronomers. Mercury is one of the more difficult objects for astronomers to observe because of its close proximity to the Sun. However, amateur astronomers can see the planet and its ever-changing phases all year, and sometimes watch it transit the Sun - the next transit is in November 2006, followed by one in May 2016.
