  2. Conjunction (astronomy) - Wikipedia

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

    As seen from a planet that is superior, if an inferior planet is on the opposite side of the Sun, it is in superior conjunction with the Sun. An inferior conjunction occurs when the two planets lie in a line on the same side of the Sun. In an inferior conjunction, the superior planet is "in opposition" to the Sun as seen from the inferior planet.

  3. 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).

  4. Solar conjunction - Wikipedia

    en.wikipedia.org/wiki/Solar_conjunction

    This is because the Sun acts as a large electromagnetic noise generator which creates a signal much stronger than the satellite's tracking signal. [ citation needed ] One example of limitations caused by the solar conjunction occurred when the NASA - JPL team put the Curiosity rover on Mars' surface in autonomous operation mode for 25 days ...

  5. Phase curve (astronomy) - Wikipedia

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

    The apparent brightness of Mercury as seen from Earth is greatest at phase angle 0° (superior conjunction with the Sun) when it can reach magnitude −2.6. [14] At phase angles approaching 180° ( inferior conjunction ) the planet fades to about magnitude +5 [ 14 ] with the exact brightness depending on the phase angle at that particular ...

  6. Orbit of Venus - Wikipedia

    en.wikipedia.org/wiki/Orbit_of_Venus

    The longitudes of perihelion were only 29 degrees apart at J2000, so the smallest distances, which come when inferior conjunction happens near Earth's perihelion, occur when Venus is near perihelion. An example was the transit of December 6, 1882: Venus reached perihelion Jan 9, 1883, and Earth did the same on December 31.

  9. Syzygy (astronomy) - Wikipedia

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

    The word is often used in reference to the Sun, Earth, and either the Moon or a planet, where the latter is in conjunction or opposition. Solar and lunar eclipses occur at times of syzygy, as do transits and occultations. The term is often applied when the Sun and Moon are in conjunction or in opposition . [4]
