  2. Orbit of Venus - Wikipedia

    en.wikipedia.org/wiki/Orbit_of_Venus

    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.

  3. Terraforming of Venus - Wikipedia

    en.wikipedia.org/wiki/Terraforming_of_Venus

    Birch calculates that increasing the rotation of Venus to an Earth-like solar cycle would require about 1.6 × 10 29 Joules [43] (50 billion petawatt-hours). Scientific research suggests that close flybys of asteroids or cometary bodies larger than 100 kilometres (60 mi) across could be used to move a planet in its orbit, or increase the speed ...

  4. Axial tilt - Wikipedia

    en.wikipedia.org/wiki/Axial_tilt

    The angles for Earth, Uranus, and Venus are approximately 23°, 97°, and 177° respectively. In astronomy, axial tilt, also known as obliquity, is the angle between an object's rotational axis and its orbital axis, which is the line perpendicular to its orbital plane; equivalently, it is the angle between its equatorial plane and orbital plane ...

  5. Venus - Wikipedia

    en.wikipedia.org/wiki/Venus

    Venus is the second planet from the Sun.It is a terrestrial planet and is the closest in mass and size to its orbital neighbour Earth.Venus has by far the densest atmosphere of the terrestrial planets, composed mostly of carbon dioxide with a thick, global sulfuric acid cloud cover.

  6. Poles of astronomical bodies - Wikipedia

    en.wikipedia.org/wiki/Poles_of_astronomical_bodies

    The direction of rotation exhibited by most objects in the solar system (including Sun and Earth) is counterclockwise. Venus rotates clockwise, and Uranus has been knocked on its side and rotates almost perpendicular to the rest of the Solar System. The ecliptic remains within 3° of the invariable plane over five million years, [2] but is now ...

  7. Cataclysmic pole shift hypothesis - Wikipedia

    en.wikipedia.org/wiki/Cataclysmic_pole_shift...

    The geographic poles are defined by the points on the surface of Earth that are intersected by the axis of rotation. The pole shift hypothesis describes a change in location of these poles with respect to the underlying surface – a phenomenon distinct from the changes in axial orientation with respect to the plane of the ecliptic that are caused by precession and nutation, and is an ...
