 It follows that in the course of a year Mars presents its various regions to the Sun, nearly like our globe, so that the length of the days and the nights, in the different latitudes, is distributed in the same manner. The extreme zones, tomd and frigid,...  The heavens [tr. by W. Lockyer] ed. by J.N. Lockyer - Síða 174eftir Amédée Victor Guillemin - 1876Heildartexta - Um bókina

...which he considered as an equatorial zone. It was from the direction of these bands that he deduced the inclination of the axis of rotation to the plane of the planet's orbit. This he estimated at about 20°, which would make the equator of Mercury inclined to... | |
