  2. Phase curve (astronomy) - Wikipedia

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

    Because the orbit of Mars is considerably eccentric its brightness at opposition can range from magnitude −3.0 to −1.4. [14] The minimum brightness is about magnitude +1.6 [14] when Mars is on the opposite site of the Sun from the Earth. Rotational variations can elevate or suppress the brightness of Mars by 5% and global dust storms can ...

    Mars −2.94 mag; Mercury −2.48 mag; Saturn −0.55 mag [2] Any exact order of the visual brightness of stars is not perfectly defined for four reasons: Stellar brightness is based on the apparent visual magnitude as perceived by the human eye, from

  5. Mars - Wikipedia

    en.wikipedia.org/wiki/Mars

    The minimum brightness is magnitude +1.86 when the planet is near aphelion and in conjunction with the Sun. [19] At its brightest, Mars (along with Jupiter) is second only to Venus in apparent brightness. [19] Mars usually appears distinctly yellow, orange, or red.

  6. Astronomy on Mars - Wikipedia

    en.wikipedia.org/wiki/Astronomy_on_Mars

    From one day to the next, the view of the Moon would change considerably for an observer on Mars than for an observer on Earth. The phase of the Moon as seen from Mars would not change much from day to day; it would match the phase of the Earth, and would only gradually change as both Earth and Moon move in their orbits around the Sun. On the ...

  7. Phase angle (astronomy) - Wikipedia

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

    For some objects, such as the Moon (see lunar phases), Venus and Mercury the phase angle (as seen from the Earth) covers the full 0–180° range. The superior planets cover shorter ranges. For example, for Mars the maximum phase angle is about 45°. For Jupiter, the maximum is 11.1° and for Saturn 6°. [1]

  8. Extraterrestrial sky - Wikipedia

    en.wikipedia.org/wiki/Extraterrestrial_sky

    The Sun as seen from Mars appears to be 5 ⁄ 8 the angular diameter as seen from Earth (0.35°), and sends 40% of the light, approximately the brightness of a slightly cloudy afternoon on Earth. On June 3, 2014, the Curiosity rover on Mars observed the planet Mercury transiting the Sun, marking the first time a planetary transit has been ...

  9. Elongation (astronomy) - Wikipedia

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

    Mars' magnitude in particular changes with elongation: it can be as low as +1.8 when in conjunction near aphelion but at a rare favourable opposition it is as high as −2.9, which translates to seventy-five times brighter than its minimum brightness. As one moves further out, the difference in magnitude that correlates to the difference in ...
