Why Are Telescopes Built On Mountains? So how comes it isn't the hottest planet then? A series of images taken by two satellites flying past Mercury captured multiple "tectonic and volcanic curiosities" as well as an impact crater on the planet. Natural color image of Venus from Mariner 10 data. It managed to keep from burning up for 127 minutes and sent color pictures back of the surface of Venus. Mercury is the closest planet to the sun, and thus receives the most direct heat. Credit: NASA Visualization Technology Applications and Development (VTAD). The eight planets of the Solar System. ESA's BepiColombo is on its wayto Mercury. The difference in temperature between Neptune and Uranus may not seem like much, but when we consider that Uranus is about a billion miles closer to the Sun than Neptune, it does seem a bit strange.

Mercury is a terrestrial planet. Image credit: 2005 Mattias Malmer, from NASA/JPL data. Because Mercury has a slow spin and short year, it takes a long time for the sun to rise and set there. Venus is about twice as far from the Sun, on average, as Mercury is, takingabout 225 Earth-days to orbit the Sun. During the day, Mercury experiences temperatures of 800 degrees Fahrenheit (430 degrees Celsius). Two images taken closer to the planet show "one of the most spectacular geological thrust systems" on Mercury. If were being quantitative, its actually extremelyhot! Either youre not explaining this well or absorption is not one of the reasons Venus is hotter than Mercury. Light-colored surfaces reflect a large portion of the Suns rays to the atmosphere, while dark-colored surfaces tend to absorb it. The only shield it has from the expanses of space is an ultra-thin exosphere made up of atoms blasted off its surface by solar radiation, wind, and micrometeoroids. Since Mercury sits closest to the Sun, it must be the hottest planet. Is Mercury the hottest or coldest planet? - Odyssey Magazine Albedo is a term used to describe how well a surface is able to reflect sunlight and heat. Drought is a complicated problem that requires lots of data. Since Mercurys atmosphere cant trap heat, the second closest planet to the Sun Venus is the hottest planet in our solar system.
