Transit When Planets Cross the Sun
When Planets Cross the Sun
Paperback Engels 1999 9781852336219Samenvatting
Although transits of planets across the Sun are rare (only Mercury and Venus orbit the Sun closer than us, and so can transit the Suns disc) amateur astronomers can observe, record and image other kinds of transits that are much more frequent. This book first tells the fascinating story of the early scientific expeditions to observe transits. It then explains how to observe transits of all sorts - even transits of aircraft as they fly between the observer and the Sun.
