The orbit of Venus is 224.7 Earth days (7.4 avg. Earth months [30.4 days]). The phases of Venus result from the planet's orbit around the Sun inside the Earth's orbit giving the telescopic observer a sequence of progressive lighting similar in appearance to the Moon's phases. It presents a full image when it is on the opposite side of the Sun.

Venus's atmosphere is rich in primordial noble gases compared to that of Earth. [95] This enrichment indicates an early divergence from Earth in evolution. An unusually large comet impact [96] or accretion of a more massive primary atmosphere from solar nebula [97] have been proposed to explain the enrichment. However, the atmosphere is ...
Venus is always brighter than the brightest stars outside the Solar System, as can be seen here over the Pacific Ocean Phases of Venus and evolution of its apparent diameter Observations of the planet Venus include those in antiquity, telescopic observations, and from visiting spacecraft.
The ancient Hebrews, like all the ancient peoples of the Near East, believed the sky was a solid dome with the Sun, Moon, planets and stars embedded in it. [4] In biblical cosmology, the firmament is the vast solid dome created by God during his creation of the world to divide the primal sea into upper and lower portions so that the dry land could appear.
Until the mid-20th century, the surface environment of Venus was believed to be similar to Earth, hence it was widely believed that Venus could harbor life. In 1870, the British astronomer Richard A. Proctor said the existence of life on Venus was impossible near its equator, [11] but possible near its poles.
Did Venus ever have oceans? Scientists have an answer. Will Dunham. December 2, 2024 at 12:53 PM. By Will Dunham. WASHINGTON (Reuters) - Earth is an ocean world, with water covering about 71% of ...
Asteroid impacts on Venus are another common phenomenon that could have shaped Venus’ surface to evolve with these geological features, although such an asteroid would have to be huge because asteroids burn up in Venus’s atmosphere and pass through clouds sulfuric and other acids. [6]
