Transits of Venus: A Popular Account of Past and Coming Transits from the First Observed by Horrocks 1639 to the Transit of 2012, Also an Account of the Successes Achieved in December 1874 and Suggestions Respecting the Transit of 1882 (Classic Reprint) by Richard A Proctor (Paperback / softback, 2015)
Excerpt from Transits of Venus: A Popular Account of Past and Coming Transits From the First Observed by Horrocks 1639 to the Transit of 2012, Also an Account of the Successes Achieved in December 1874 and Suggestions Respecting the Transit of 1882 The approach of the transit of Venus on December 6 (partly visible in this country), and very favourably visible throughout its entire duration in the United States, renders necessary a new edition of this work. Very few changes have been made, as the second and third editions both followed the transit of 1874, and very little has been done in the interval which renders change necessary or desirable. The estimates w regarded as probably nearest the truth assign to the sun a distance of about 92,885,000 miles, corresponding to a mean equatorial long horizontal solar parallax of 8 80. It remains to be seen whether observations made on the approaching transit will modify this value. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
