Consequently, Venus transits above Earth only occur when an inferior conjunction takes place during some days of June or December, the time where the orbits of Venus and Earth cross a straight line with the Sun. [185] This results in Venus transiting above Earth in a sequence of currently 8 years, 105.5 years, 8 years and 121.5 years, forming ...
The full cycle from new to full to new again takes 584 days (the time it takes Venus to overtake the Earth in its orbit). Venus (like the Moon) has 4 primary phases of 146 days each. The planet also changes in apparent size from 9.9 arc seconds at full (superior conjunction) up to a maximum of 68 arc seconds at new (inferior conjunction). [1]

In a series of subsequent papers, Basilevsky and colleagues extensively developed a model that Guest and Stofan (1999) [22] termed the "directional history" for Venus evolution. [ 23 ] [ 24 ] [ 25 ] The general idea is that there is a global stratigraphy that progresses from heavily deformed tessera, to heavily deformed, then moderately ...
The second sphere explains the movement of the Sun and the Moon on the ecliptic plane. The third sphere was supposed to move on a “latitudinally inclined” circle and explain the latitudinal motion of the Sun and the Moon in the cosmos. Four spheres were assigned to Mercury, Venus, Mars, Jupiter, and Saturn, the only known planets at that time.
Venus, our closest planetary neighbor, is sometimes called Earth's twin based on their similar size and rocky composition. While its surface is baked and barren today, might Venus once also have ...
