What is the lowest temperature on Mercury?
-290°F
Mercury’s surface temperatures are both extremely hot and cold. Because the planet is so close to the Sun, day temperatures can reach highs of 800°F (430°C). Without an atmosphere to retain that heat at night, temperatures can dip as low as -290°F (-180°C).
What is the hottest temperature on Mercury?
800 °F
Mercury is hot. If we’re being quantitative, it’s actually extremely hot! As the closest planet to the Sun, it completes an orbit in just 88 Earth-days, achieving a maximum temperature during the day of a whopping 700 Kelvin (427 °C / 800 °F) at its hottest, equatorial locations.
Is Mercury the coldest planet at night?
Despite being coldest to the sun, Mercury is actually cooler than Venus due to its slow rotation and thin atmosphere….The Hottest And Coldest Planets Of Our Solar System.
| Rank | Planet and Pluto | Surface Temperature |
|---|---|---|
| 1 | Mercury | 800°F (430°C) during the day, -290°F (-180°C) at night |
| 2 | Venus | 880°F (471°C) |
| 3 | Earth | 61°F (16°C) |
| 4 | Mars | minus 20°F (-28°C) |
Why is Mercury not the warmest planet?
Because it is so close to the sun, it can be very hot. On its sunny side, Mercury can reach a scorching 800 degrees Fahrenheit! (But Mercury is not the hottest planet in the solar system. On its dark side, Mercury gets very cold because it has almost no atmosphere to hold in heat and keep the surface warm.
What is the temperature on the surface of mercury?
Temperatures on Mercury are extreme. During the day, temperatures on the surface can reach 800 degrees Fahrenheit (430 degrees Celsius). Because the planet has no atmosphere to retain that heat, nighttime temperatures on the surface can drop to minus 290 degrees Fahrenheit (minus 180 degrees Celsius).
Is there any water ice on the surface of mercury?
Because the planet has no atmosphere to retain that heat, nighttime temperatures on the surface can drop to minus 290 degrees Fahrenheit (minus 180 degrees Celsius). Mercury may have water ice at its north and south poles inside deep craters, but only in regions of permanent shadow.
Why does Mercury have no weather to speak of?
Due to the tenuous atmosphere, Mercury really has no weather to speak of other than wild fluctuations in temperature. In fact, Mercury has the largest diurnal temperature spread of any planet in our solar system. This is explained by a few factors.
Which is the coldest planet in the Solar System?
It can be as cold as -290 degrees Fahrenheit (-179 degrees Celsius) on Mercury at night. Temperatures for the gas and ice giants (Jupiter, Saturn, Uranus, and Neptune) are taken from a level in the atmosphere equal in pressure to sea level on Earth. Page Updated: June 26, 2020
