  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. Planetary phase - Wikipedia

    en.wikipedia.org/wiki/Planetary_phase

    The superior planets, orbiting outside the Earth's orbit, do not exhibit a full range of phases since their maximum phase angles are smaller than 90°. Mars often appears significantly gibbous, it has a maximum phase angle of 45°. Jupiter has a maximum phase angle of 11.1° and Saturn of 6°, [1] so their phases are almost always full.

  7. 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]

  8. List of conjunctions (astronomy) - Wikipedia

    en.wikipedia.org/wiki/List_of_conjunctions...

    Conjunction of Mercury and Venus, appearing above the Moon, at the Paranal Observatory. This is a list of the Solar System's recent planetary conjunctions (in other words, when two planets look close together) for the period 2005–2020.

  9. Venus - Wikipedia

    en.wikipedia.org/wiki/Venus

    As it orbits the Sun, Venus displays phases like those of the Moon in a telescopic view. The planet appears as a small and "full" disc when it is on the opposite side of the Sun (at superior conjunction). Venus shows a larger disc and "quarter phase" at its maximum elongations from the Sun, and appears at its brightest in the night sky. The ...
