The exceptions – the planets with retrograde rotation – are Venus and Uranus. Venus's axial tilt is 177°, which means it is rotating almost exactly in the opposite direction to its orbit. Uranus has an axial tilt of 97.77°, so its axis of rotation is approximately parallel with the plane of the Solar System.
Representation of Venus (yellow) and Earth (blue) circling around the Sun. Venus and its rotation in respect to its revolution. Venus has an orbit with a semi-major axis of 0.723 au (108,200,000 km; 67,200,000 mi), and an eccentricity of 0.007. [1] [2] The low eccentricity and comparatively small size of its orbit give Venus the least range in ...
An animation explaining why the planet Mercury may appear to move "backwards", or retrograde across Earth's sky. Apparent retrograde motion is the apparent motion of a planet in a direction opposite to that of other bodies within its system, as observed from a particular vantage point.

Hebrew astronomy refers to any astronomy written in Hebrew or by Hebrew speakers, or translated into Hebrew, or written by Jews in Judeo-Arabic.It includes a range of genres from the earliest astronomy and cosmology contained in the Bible, mainly the Tanakh (Hebrew Bible or "Old Testament"), to Jewish religious works like the Talmud and very technical works.
The Satan does not inhabit or supervise the underworld – his sphere of activity is the human world – and is only to be thrown into the fire at the end of time. [87] He appears throughout the Old Testament not as God's enemy but as his minister, "a sort of Attorney-General with investigative and disciplinary powers", as in the Book of Job. [87]
Venus is similar in size and distance from the sun when compared with Earth, and some researchers believe the planet might have even had an Earth-like climate at some point.
Venus may have had liquid surface water early in its history with a habitable environment, [24] [25] before a runaway greenhouse effect evaporated any water and turned Venus into its present state. [26] [27] [28] The rotation of Venus has been slowed and turned against its orbital direction by the currents and drag of its atmosphere. [29]
