  2. Opposition (astronomy) - Wikipedia

    en.wikipedia.org/wiki/Opposition_(astronomy)

    Seen from a superior planet, an inferior planet on the opposite side of the Sun is in superior conjunction with the Sun. An inferior conjunction occurs when the two planets align on the same side of the Sun. At inferior conjunction, the superior planet is "in opposition" to the Sun as seen from the inferior planet (see the diagram).

    en.wikipedia.org/wiki/Vakri_grahas

    Vakragati means retrograde motion. As the Earth passes by a planet that particular planet appears to move backwards i.e. westward, amid the stars, this phenomenon is called retrograde motion, which motion invariably occurs at a time when that planet is visible for a relatively longer period. the approximate midpoint of which period in respect of the superior planets coincides with opposition ...

  5. Astronomy on Mars - Wikipedia

    en.wikipedia.org/wiki/Astronomy_on_Mars

    The axial tilt and eccentricity of Earth (and Mars) are by no means fixed, but rather vary due to gravitational perturbations from other planets in the Solar System on a timescale of tens of thousands or hundreds of thousands of years. Thus, for example Earth's eccentricity, currently about 1% regularly fluctuates and can increase up to 6%.

  6. Apparent retrograde motion - Wikipedia

    en.wikipedia.org/wiki/Co-orbital_configuration

    In astronomy, a co-orbital configuration is a configuration of two or more astronomical objects (such as asteroids, moons, or planets) orbiting at the same, or very similar, distance from their primary; i.e., they are in a 1:1 mean-motion resonance. (or 1:-1 if orbiting in opposite directions). [1]

  9. Inferior and superior planets - Wikipedia

    en.wikipedia.org/wiki/Inferior_and_superior_planets

    In the reference frame of the Earth, where the terms were originally used, the inferior planets are Mercury and Venus, while the superior planets are Mars, Jupiter, Saturn, Uranus and Neptune. Dwarf planets like Ceres or Pluto and most asteroids are 'superior' in the sense that they almost all orbit outside the orbit of Earth.
