It is also one of the coldest. Earth’s lowest air temperature, -135ºF (-93ºC), was recorded in Antarctica in 2010. Scientists recently discovered the hottest planet ever found – with a surface temperature greater than some stars. OGLE-2005-BLG-390Lb is the coldest planet having the temperature of just 50 degree above absolute zero- -223degree Celsius.It is a rocky planet … Seven years of satellite temperature data show that the Lut Desert in Iran is the hottest spot on Earth. This list will introduce you to some of the Coldest Planets in the space, and we like to call them cold hell. It was … THE COLDEST. The average temperatures of planets in our solar system are: Mercury - 800°F (430°C) during the day, -290°F (-180°C) at night; Venus is the exception, as its proximity to the Sun and dense atmosphere make it our solar system's hottest planet. Hottest Planet. (NASA maps by Jesse Allen and Robert Simmon, using MODIS data from Mildrexler et al., 2011. Why is Venus the hottest planet even though Mercury is closer to the sun? Because Mercury doesn’t have an atmosphere, the side of the planet that faces the sun can reach temperatures of 800 degrees, but on the side that faces away from the sun and its lowest temperature can drop to -290 degrees Fahrenheit. Venus is the hottest planet among all the eight planets. Mean Temperature:-225 Degree Celsius. The Lut Desert was hottest during 5 of the 7 years, and had the highest temperature overall: 70.7°C (159.3°F) in 2005. And the ongoing exploration of our own solar system has revealed some pretty weird contenders, too. Because Mercury doesn't have an atmosphere, the side of the planet that faces the sun can reach temperatures of 426 degrees C, but on the side that faces away from the sun and its lowest temperature can drop to -143 degrees Celsius. Although Venus is the second closest planet to the Sun, it is still the hottest. About Venus. As the hunt for planets outside our own solar system continues, we have discovered many other worlds with extreme features. It is a dwarf planet in the Kuiper belt, a ring of bodies beyond Neptune. Since then, scientists have discovered that surface ice temperatures can dip as low as -144ºF (-98ºC). Planetary surface temperatures tend to get colder the farther a planet is from the Sun. It is also one of the coldest. Mercury has the greatest range, going from 100′K to 700′K (it is partially tidal locked with the sun, and has very long days, so one side will stay in shade for months and no effective atmosphere to transfer heat). Asked by: Akil Answer Mercury is closest to the sun, this is true. Venus is the second planet from the Sun and is the brightest planet in the solar system. Venus has a thick atmosphere that blankets the planet, keeping its temperature at an average of 864 F (462 C). OGLE-2016-BLG-1195Lb. 7. Highs and Lows on Planet Earth.

Well, we have already covered some of the hottest planets out there, it’s time for us to know more about colder ones. It comprises of an atmosphere full of carbon dioxide and clouds made of sulfuric acid. Pluto . The hottest planet in our solar system is Venus, When it comes to temperature, distance from the Sun matters, but it takes a backseat to wrapping a planet in … As the planet closest to the sun, you might expect Mercury to be one of the hottest planets and it is. The lists of hottest and coldest planets in the solar System are discussed below: 9. Cold. However, because of its proximity to the sun it lacks an atmosphere. With that quick primer, let’s dig into some of the hottest insights in this cool data visualization. Surface Temperature: Unknown. The hottest planet, incidentally, is Venus, the second body from the sun.
