  2. Orbit of Mars - Wikipedia

    en.wikipedia.org/wiki/Orbit_of_Mars

    Mars comes closer to Earth more than any other planet save Venus at its nearest—56 million km is the closest distance between Mars and Earth, whereas the closest Venus comes to Earth is 40 million km. Mars comes closest to Earth every other year, around the time of its opposition, when Earth is sweeping between the Sun and Mars. Extra-close ...

  3. Transit of Earth from Mars - Wikipedia

    en.wikipedia.org/wiki/Transit_of_Earth_from_Mars

    Earth and Moon transiting the Sun in 2084, as seen from Mars. Image created using SpaceEngine Earth and Moon from Mars, as photographed by the Mars Global Surveyor. A transit of Earth across the Sun as seen from Mars takes place when the planet Earth passes directly between the Sun and Mars, obscuring a small part of the Sun's disc for an observer on Mars.

  4. Delta-v budget - Wikipedia

    en.wikipedia.org/wiki/Delta-v_budget

    The transit time is calculated as ((+) /) / / years. Note that the values in the table only give the Δv needed to get to the orbital distance of the planet. The speed relative to the planet will still be considerable, and in order to go into orbit around the planet either aerocapture is needed using the planet's atmosphere, or more Δv is needed.

  5. Astronomical transit - Wikipedia

    en.wikipedia.org/wiki/Astronomical_transit

    However, because a transit is dependent on the point of observation, the Earth itself transits the Sun if observed from Mars. In the solar transit by the Moon captured during calibration of the STEREO B spacecraft's ultraviolet imaging, the Moon appears much smaller than it does when seen from Earth , because the spacecraft–Moon separation ...

  6. Transit time - Wikipedia

    en.wikipedia.org/wiki/Transit_time

    The time for a radar reflection to return; Sun transit time, the time at which the sun passes over the observer's meridian line; The transit time factor for an acceleration voltage, used in accelerator physics; In breath gas analysis, the delay between a gas sample being removed from the patient circuit and the sample being analyzed by a machine

  7. Memnonia quadrangle - Wikipedia

    en.wikipedia.org/wiki/Memnonia_quadrangle

    The Memnonia quadrangle is also referred to as MC-16 (Mars Chart-16). [1] The quadrangle is a region of Mars that covers latitude -30° to 0° and longitude 135° to 180°. [2] The western part of Memnonia is a highly cratered highland region that exhibits a large range of crater degradation. Memnonia includes these topographical regions of Mars:

  8. Transit of Phobos from Mars - Wikipedia

    en.wikipedia.org/wiki/Transit_of_Phobos_from_Mars

    Mars Global Surveyor orbits Mars in a Sun-synchronous polar orbit with orbital period 117.65 minutes, moving from south pole to north pole, and continuously points its camera straight down. The result is an image in the form of a very long thin vertical strip, where the pixels in the top part of the image are imaged nearly one hour after those ...

  9. Planetary transits and occultations - Wikipedia

    en.wikipedia.org/wiki/Planetary_transits_and...

    The next time a mutual planetary transit or occultation will happen (as seen from Earth) will be on 22 November 2065 at about 12:43 UTC, when Venus near superior conjunction (with an angular diameter of 10.6") will transit in front of Jupiter (with an angular diameter of 30.9"); however, this will take place only 8° west of the Sun, and will therefore not be visible to the unaided/unprotected ...
