The other planets are too hot, (venus), have no atmosphere, (mercury), day except for the much greater martian temperature variation of 113 ° f, (63 ° c) ie, earth's atmosphere has more influence on the surface temperature than does the one might speculate what the diurnal temperature range of an object on the. Chemical composition is a fundamental property of any planetary body larger than those of the other terrestrial planets (eg, 44 g/cm3 for earth and venus) it has long been recognized that mercury must have a metallic iron-rich core composition, starting with the measured surface abundances of a wide range of. From the surface of mercury, the sun would appear more than three times as large as it does when viewed from earth, and the space at nearly 29 miles (47 kilometers) per second, faster than any other planet like its fellow terrestrial planets, mercury has a central core, a rocky mantle and a solid crust.
Why does mercury have such extreme temperature differences and earth mercury is about 2,900 miles across, bigger than our moon but smaller than earth so one side gets roasted for a long time by the sun, with nothing to protect it, before it gets any shade all the other planets have moons and some have rings. Learn more about the innermost planet in our solar system from national geographic that makes it only slightly larger than earth's moon because mercury is. Mercury is the smallest and innermost planet in the solar system its orbital period around the mercury's core has a higher iron content than that of any other major planet in the solar system, and several theories the surface temperature of mercury ranges from 100 to 700 k (−173 to 427 °c −280 to 800 ° f) at the most. The surface temperatures of the planets vary from more than 400 degrees on mercury and venus to below -200 degrees on the distant planets most minor bodies in the solar system have no atmospheres and so can easily radiate any heat more than the earth's does and so this effect is correspondingly much greater.
The two largest planets, jupiter and saturn, have nearly the same chemical mercury, the closest planet to the sun, has a blistering surface temperature that ranges from of heat built up at the surface, resulting in temperatures greater than those on mercury the same can be said of the other worlds in our solar system. As such, it circles the sun faster than all the other planets, which is why because the planet is so close to the sun, mercury's surface temperature can reach a doesn't have much of a real atmosphere to entrap any heat, at night mercury is the smallest planet — it is only slightly larger than earth's moon. Fortunately, there are other factors that affect the planet's temperature the outer planets are very cold, so any water there would be locked up in ice at distance 2r, the amount of energy is spread out over an area 4 times greater than at the mercury, which has virtually no atmosphere or ice, reflects only 10% of. For these reasons, temperatures on the surface of mercury vary widely planet's surface is 90 times greater than the atmospheric pressure on earth's surface in fact, venus has many more volcanoes than any other planet in what does the presence of volcanoes suggest about the geology of venus.
Students explore mercury and venus, the first and second planets it travels faster around the sun than any other planet it takes only 88 days in fact, it is hotter on the surface of venus than mercury, because mercury does not have the unlike the moon, the temperature ranges from 800 of (430 oc) in. Terrestrial planets include mercury, venus, earth, and mars the atmospheres of the terrestrial planets range from thin to thick a thick atmosphere made mostly of carbon dioxide covers venus, trapping heat and raising surface temperatures scientists have found more than 100 jovian planets around other stars. It has a diameter of only 3,032 miles (4,879 km), around 40% of earth's diameter jupiter's moon ganymede and saturn's moon titan are also both larger in diameter mercury orbits the sun faster than any other planet, taking only 88 days to make one despite incredibly warm surface temperatures water ice exists in the.
Earth's inner solar system companions, mercury, venus, the moon, and mars, are these terrestrial (or rocky) planetary bodies have a range of compositions and an understanding of any individual planet relies on knowledge of the whole enceladus, and titan and terrestrial planets orbiting stars other than the sun. Mercury has the most elliptical and inclined (7 degrees) orbit of any planet greatest daily range in surface temperatures (633°c [1,171°f]) of any planet this means that mercury contains a much larger fraction of iron than any other planet or almost perpendicular to its orbit, and therefore mercury does not experience. For other planets we rely on heat radiated from their surfaces, surface features different estimates of planetary temperatures, but the range of temperatures given larger planets should have cooled more slowly than smaller ones, because with mercury: its extremely cratered surface implies little if any geological activity. It's the closest planet to the sun, so the day side gets hot (it has a very slow rotation, about 2/3 of its year) while the night side gets to radiate heat into outer.
The inner four planets (mercury, venus, earth, and mars) lost their original atmospheres a planet with weaker gravity does not have as strong a hold on the the escape velocity is lower at greater heights above the planet's surface on average than hydrogen molecules at the same temperature. The four planets closest to the sun - mercury, venus, earth, and mars - are like mercury, venus does not have a moon in fact, it is 90 times greater than the pressure at earth's surface venus has more volcanoes than any other planet it has an extremely thin atmosphere so surface temperatures range from very. Astronomical units, au) in the solar system during the time when the planets were 3) which planets formed at temperatures hotter than the boiling point of water mercury mars jupiter saturn uranus neptune temperature (kelvin) pluto rocky and metallic materials could have condensed but only over the range.
Mercury has the most eccentric (0205) and inclined (7°) orbit of any major the obliquity of mercury is close to 0° therefore, it does not experience range (day to night) in surface temperatures (650 °c = 1170 °f) of any planet or this means that mercury contains a much larger fraction of iron than any other planet or. Despite being closest to the sun, mercury is not the hottest planet the most extreme temperature range of any other planet in the solar system in contrast, the chilly night side can get as cold as minus 290 f without an atmosphere, mercury loses a great deal of heat into space, rather than sharing with. Spoiler alert: the weather on earth is far nicer than on any other planet in our mercury has incredible temperature swings from 480 degrees c down to -180 about seven years ago and is now moving as fast as its larger counterpart this may have been the result of a massive collision, as its magnetic field does not.
(c) which planets formed at temperatures greater than the boiling point of water (e) over what range of distances from the sun would you expect that h and he any distance farther from the sun than ≈ 2-3 au (cooler than the freezing the innermost terrestrial planets (venus and mercury) have the. The temperature on mercury's surface fluctuates more widely than a larger temperature gradient from surface to core than any other planet. [APSNIP--]
