The surfaceof Mars is therefore much colder than the Earth would be at that distance from the Sun. Mars has a very thin atmosphere composed mostly of the tiny amount of remaining carbon dioxide (95.3%) plus nitrogen (2.7%), argon (1.6%) and traces of oxygen (0.15%) and water (0.03%...
Mars is the fourth planet from the Sun and the seventh largest: orbit: 227,940,000 km (1.52 AU) from Sun diameter: 6,794 km mass: 6.4219e23 kg Mars (Greek: Ares) is the god of War. The planet probably got this name due to its red color; Mars is some

As inputs, the mean Mars-Sun distance of 1.52 AU was used with a solar zenith angle of 0∘, for a solar longitude of 0∘, at 0∘N,0∘E (using the ‘Looking up to the Sun’ viewing geometry). The Planetary Spectrum Generator’s standard martian atmospheric profile with no...
Satellite maps - Mars is the fourth planet from the Sun in the Solar System. The planet is named after the Roman god of war, Mars. It is often described as the Red Planet, as the iron oxide prevalent on its surface gives it a reddish appearance.

Mars, at a heliocentric distance of approximately 1.5 AU, exemplifies a terrestrial body that is affected by both a slightly greater distance from the Sun than Earth and a lower gravitational field at the surface. The latter results from Mars' smaller size. The radius of Mars is about 3395 ...

(AU is short for "astronomical unit," the distance from Earth to the sun, which is about 93 million miles, or 150 million km. And "hyperbolic excess velocity" just refers to the spacecraft's speed.) "More-modest figures can still fulfill the mission, such as 40 km/s with an ...
Located at the centre of the solar system and influencing the motion of all the other bodies through its gravitational force is the Sun, which in itself contains more than 99 percent of the mass of the system. The planets, in order of their distance outward from the Sun, are Mercury, Ven...
