  2. Orbit of Mars - Wikipedia

    en.wikipedia.org/wiki/Orbit_of_Mars

    Extra-close oppositions of Mars happen every 15 to 17 years, when we pass between Mars and the Sun around the time of its perihelion (closest point to the Sun in orbit). The minimum distance between Earth and Mars has been declining over the years, and in 2003 the minimum distance was 55.76 million km, nearer than any such encounter in almost ...

  3. Astronomy on Mars - Wikipedia

    en.wikipedia.org/wiki/Astronomy_on_Mars

    Twilight lasts a long time after the Sun has set and before it rises, because of all the dust in Mars' atmosphere. At times, the Martian sky takes on a violet color, due to scattering of light by very small water ice particles in clouds. [4] Generating accurate true-color images of Mars's surface is surprisingly complicated. [5]

  4. Mars - Wikipedia

    Mars is the fourth planet from the Sun.The surface of Mars is orange-red because it is covered in iron(III) oxide dust, giving it the nickname "the Red Planet". [22] [23] Mars is among the brightest objects in Earth's sky, and its high-contrast albedo features have made it a common subject for telescope viewing.

    L 4 is the Sun–Earth Lagrange point located close to the Earth's orbit 60° ahead of Earth. Asteroid (706765) 2010 TK 7 is the first discovered tadpole orbit companion to Earth, orbiting L 4; like Earth, its mean distance to the Sun is about one astronomical unit.

    en.wikipedia.org/wiki/Mare_Boreum_quadrangle

    The Mare Boreum quadrangle is one of a series of 30 quadrangle maps of Mars used by the United States Geological Survey (USGS) Astrogeology Research Program. The Mare Boreum quadrangle is also referred to as MC-1 (Mars Chart-1). [1] Its name derives from an older name for a feature that is now called Planum Boreum, a large plain surrounding the ...

  8. Memnonia quadrangle - Wikipedia

    en.wikipedia.org/wiki/Memnonia_quadrangle

    Dust storms are frequent, especially when the spring season begins in the southern hemisphere. At that time, Mars is 40% closer to the Sun. The orbit of Mars is much more elliptical then the Earth's. That is the difference between the farthest point from the Sun and the closest point to the Sun is very great for Mars, but only slight for the Earth.
