火星介绍简短英文

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！

Mars 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.

别走开！让我来考考你，对于火星了解有多少。一谈到火星，我们脑海里会浮现出一个红色的星球。它是太阳系的八大行星之一，离我们的距离不算太远，属于类地行星的一种。它的表面覆盖着厚厚的沙丘和砾石……是不是瞬间就会写这篇英语作文了。

另外，除了传统的客观第三人称视角，我们还可以将火星拟人化，用第一人称的方式写这篇作文，会更加让读者眼前一亮。在我给出的这三篇文章中，前两篇是第三人称，最后一篇是第一人称，一起来学习和借鉴一下吧！

作文示例一：

Mars is one of the eight major planets of the solar system. It is the fourth planet in our solar system from inside to outside. It belongs to the terrestrial planet and has a diameter of about half of the earth. The period of its revolving on its axis is similar to the earth, while the period of its orbiting around the sun is two times of the earth.The nearest distance from Mars to the earth is about 55 millions kilometers, while the farthest distance is about 400 million kilometers.

作文翻译一：

火星是太阳系八大行星之一。它是我们太阳系从内到外的第四颗行星。它属于类地行星，直径大约是地球的一半。它绕轴旋转的周期与地球相似，而它绕太阳运行的周期是地球的两倍。从火星到地球的最近距离约为5500万公里，而最远距离约为4亿公里。

作文示例二：

The Orange red appearance of Mars is caused by iron oxide on its surface. Mars is basically a desert planet with dunes, gravels everywhere. There is no liquid water on Mars. With thin carbon dioxide and dust in the atmosphere it is cold and try all year round. In winter the cold temperature can reach minus 130 degrees centigrade while in summer time it can rise to 27 degrees Celsius. Strong sand storms visit this planet every year. The Martian poles have dry ice caps with seasonal fluctuation.

作文翻译二：

火星的橙红色外观是由其表面的氧化铁形成的。火星基本上是一个沙漠星球，沙丘、砾石无处不在。火星上没有液态水。由于大气中二氧化碳和灰尘稀薄，天气寒冷，全年无休。在冬天，寒冷的温度可以达到零下130摄氏度，而在夏天，它可以上升到27摄氏度。每年都会有强烈的沙尘暴袭击这个星球。火星两极有季节性波动的干冰冠。

作文示例三：

I am Mars. I have a striking red appearance and I am in the favourable position opposite the sun. The mean distance of me from the sun is about 228 million kilometres，my revolution is about 687 days, almost twice that of the earth. At those times，I am at my closest point to the sun, the distance from the earth is about 56 million kilometres.This situation occurs every 15 to 17 years. When I am at my greatest distance from the sun which is about 63 million kilometres from the earth. I rotate on my axis with a period of about 24 hours and 37 minutes.

作文翻译三：

我是火星，我拥有着醒目的红色外表。我处在面对太阳的最有利位置。我与太阳的平均距离约为2.28亿公里，我的公转周期约687天，几乎是地球的两倍。当我在离太阳最近的点时，我距地球约5600万公里，这种情况每15到17年发生一次。当我离太阳最远时（大约是63万公里）我绕轴自转的周期约为24小时37分钟。
