The Solar SystemByDelete this text and causa your name here.IntroductionAs far as we know, there argon nine satellites locked in orbit around the Sun. Only one, our own farming, supports liveliness. that there are countless other suns throughout countless galaxies unlogical across the expanse of the universe. We still dont know if life equals on another planet in some other galaxy. atomic number 80Named for the wing-footed messenger of the Roman gods, hydrargyrum races around its orbit at a dizzying speed of 30 miles (48 kilometers) per second, making the Mercurial year only 88 Earth days long. In contrast, one rotation around its axis vertebraor a single daytakes almost 59 Earth days.GeologyMariner 10 gave us a wealth of in createation some Mercury when it approached the planet in 1974 and 1975. Because Mercury has no water and just now any airwave, no erosion has taken place on its surface. We fascinate Mercury much the way it was soon after it formed. CoreWe lettered that Mercury has an extremely weak magnetic field, which could indicate a hot metallic core, much(prenominal) as molten iron. Geologists think Mercury may be the most iron-rich planet in the solar system. CrustMercurys insolence seems to be silicate, like that of Earth.CratersThe planets surface, viewed for the first off clip via Mariners cameras, is covered by craters. The battering occurred during the other(a) period of the solar system when clumps of material were ramming into each other to form the planets. AtmosphereMercury doesnt have what we think of as an atmospherethat is, a gaseous envelope that produces clouds and weather or protects the surface of the planet from some of the harmful solar radiation. The weak magnetic field on Mercury captures only the barest perceptible trace of charged particles from the Sun. VenusShrouded in the cloak of mystery, Venus, our nearest planetary neighbor, takes the name of the Roman goddess of love. For some noncitizen reason, Ven us rotates on its axis in retrogradethat is, in the reverse gear direction of its revolution around the Sun.GeologyGeologically, Venus appears to have some similarities to Earth. Its crust is probably granitic, overlying a basaltic mantle and a iron-nickel core. The geological activity that we are familiar with on Earth seems not to exist on Venus, except for the presence two volcanoes along a daub line.... ...p17Uranus19.1884 years16 hours14.544.1015Neptunegod of the oceanic abyss blue sea30.06165 years18 hours17.233.888netherworldgod of the underworld39.44248 years6.4 days.002?0.12-0.301* AU = astronomic Unit (Earth = 1)ConclusionWe know more and more all the time about our own solar system. During the past 15 years, space probes such as the Mariner and Voyager missions have given us tremendous peak about all the planets in this system. Tiny by comparison to the milky Way, our solar system is awesome, nevertheless, when considered in human scale.
