火星 Mars:Mars is the fourth planet from the Sun in the Solar System. 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.[13] Mars is a terrestrial planet with a thin atmosphere, having surface features reminiscent both of the impact craters of the Moon and the volcanoes, valleys, deserts, and polar ice caps of Earth. The rotational period and seasonal cycles of Mars are likewise similar to those of Earth, as is the tilt that produces the seasons. Mars is the site of Olympus Mons, the highest known mountain within the Solar System, and of Valles Marineris, the largest canyon. The smooth Borealis basin in the northern hemisphere covers 40% of the planet and may be a giant impact feature.[14][15]Until the first successful flyby of Mars occurred in 1965, by Mariner 4, many speculated about the presence of liquid water on the planet's surface. This was based on observed periodic variations in light and dark patches, particularly in the polar latitudes, which appeared to be seas and continents; long, dark striations were interpreted by some as irrigation channels for liquid water. These straight line features were later explained as optical illusions, though geological evidence gathered by unmanned missions suggest that Mars once had large-scale water coverage on its surface.[16] In 2005, radar data revealed the presence of large quantities of water ice at the poles,[17] and at mid-latitudes.[18][19] The Mars rover Spirit sampled chemical compounds containing water molecules in March 2007. The Phoenix lander directly sampled water ice in shallow Martian soil on July 31, 2008.[20]Mars has two moons, Phobos and Deimos, which are small and irregularly shaped. These may be captured asteroids, similar to 5261 Eureka, a Martian trojan asteroid. Mars is currently host to three functional orbiting spacecraft: Mars Odyssey, Mars Express, and the Mars Reconnaissance Orbiter, and one on the surface, the Mars Exploration Rover Opportunity. Defunct spacecraft on the surface include MER-A Spirit, and several other inert landers and rovers, both successful and unsuccessful such as the Phoenix lander, which completed its mission in 2008. Observations by NASA's now-defunct Mars Global Surveyor show evidence that parts of the southern polar ice cap have been receding.[21] Observations by the Mars Reconnaissance Orbiter have revealed possible flowing water during the warmest months on MarsMars can easily be seen from Earth with the naked eye. Its apparent magnitude reaches −3.0.a brightness surpassed only by Jupiter, Venus, the Moon, and the Sun. Optical ground based telescopes are typically limited to resolving features about 300 km (186 miles) across when Earth and Mars are closest, because of Earth's atmosphere.这是维基百科对火星的专业介绍，希望您可以采纳！谢谢！

火星是太阳系八大行星之一，英文简介如下：
Mars is the fourth closest planet to the sun and the second smallest planet in the solar system after mercury. It is one of the four earth like planets in the solar system. Mars is called the red planet because its soil is rich in iron and red.
The Martian atmosphere is dominated by carbon dioxide，which is thin and cold. It is full of impact craters，canyons，sand dunes and gravel，and there is no stable liquid water.
火星是离太阳第四近的行星，也是太阳系中仅次于水星的第二小的行星，为太阳系里四颗类地行星之一。火星因为土壤富含铁质呈现红色，所以它被称为红色星球。火星大气以二氧化碳为主，既稀薄又寒冷，遍布撞击坑、峡谷、沙丘和砾石，没有稳定的液态水。
火星的特点：
1、地势崎岖
火星坚硬的表面上分布着火山、峡谷、河床等，火星上的恶劣的天气条件，导致火星的表面发生着多种化学反应，形成了奇特的火星地貌。
2、空气稀薄
火星上有着稀薄的大气，主要由二氧化碳（CO2），氩气（Ar），氮气（N2）及少量的氧气与水蒸气组成，如此稀薄的空气，导致了火星上没有生命的存在。
3、无环
火星周围没有环。火星上有环形山，有大峡谷，但火星的四周却没有环。
4、无生命迹象
火星表面的空气极为稀薄，据目前探测的结果来看，在火星的表面不存在生命，科学家尚未确定火星过去和未来存在生命的可能性。
