These factors contribute to the fact that the surface of Mercury has the greatest temperature range of any planet or natural satellite in our solar system.
The surface temperature on the side of Mercury closest to the Sun reaches 427 degrees Celsius, a temperature hot enough to melt tin.
What planet has the most extreme temperatures?
Without an atmosphere, Mercury loses a great deal of heat into space, rather than sharing with its night side. The hottest planet, incidentally, is Venus, the second body from the sun. Venus has a thick atmosphere that blankets the planet, keeping its temperature at an average of 864 F (462 C).

Why does Mercury have the largest temperature difference of all the planets?
What Planet Has the Largest Temperature Difference? The conditions on every planet in the solar system are either much colder or much hotter than on Earth. There is such a large temperature difference on Mercury because it lacks an atmosphere.
Which planet has the most violent weather?
Mercury
- Our most distant planet, Neptune, is home to extreme weather similar to the other gas giants.
- Neptune has over a dozen moons, the largest of which is Triton.
- Pluto experiences MASSIVE swings in temperature due to its highly elliptical orbit.
Why are the days on Mercury very hot and the nights very cold?
It is very hot during the day (over 400°C) because Mercury is so close to the Sun. At night it is very cold because Mercury loses almost all its heat since there is almost no atmosphere to keep the warmth there. The temperature can fall to almost -175°C.
Which planet has highest temperature?
Venus is the second planet from the sun and has a temperature that is maintained at 462 degrees Celsius, no matter where you go on the planet. It is the hottest planet in the solar system. So what makes Venus hotter than Mercury? Mercury doesn’t have any atmosphere, and atmosphere can hold and trap heat.
Which planet has the coldest temperature?
Uranus is the coldest planet in our Solar System, with a lowest recorded temperature of -224°C. Despite its distance from the Sun, the largest contributing factor to its frigid nature has to do with its core.
What is true of Mars?
The surface of Mars is surprisingly smooth and featureless. Because of its axial tilt and more elliptical orbit, Mars’ polar caps change size even more than the Earth’s do. True. The seasonal polar caps on Mars, which grow and shrink over the year, are primarily carbon dioxide.
Which planet has the fastest rate of orbit?
Below is a list of the planet’s orbital speeds in order from fastest to slowest.
- Mercury is the fastest planet, which speeds around the sun at 47.87 km/s.
- Venus is the second fastest planet with an orbital speed of 35.02 km/s, or 78,337 miles per hour.
Which planet revolves around the sun the fastest and how long does it take?
It only takes 88 days for Mercury to orbit around the sun. No other planet travels around the sun faster. The planet Venus is so bright in the night sky that you may think it is a star.
Why Venus is called Morning and Evening Star?
Originally, the terms “morning star” and “evening star” applied only to the brightest planet of all, Venus. Far more dazzling than any of the actual stars in the sky, Venus does not appear to twinkle, but instead glows with a steady, silvery light.
Why is Mars the hottest planet?
Mars also has a hard time holding onto the heat it does get. On Earth, much of the sun’s heat gets trapped in our atmosphere, which acts like a blanket to keep our planet warm. But Mars’ atmosphere is about 100 times thinner than Earth’s — so heat from the sun can easily escape.
Is Mars hotter than Mercury?
The carbon dioxide traps most of the heat from the Sun. The cloud layers also act as a blanket. The result is a “runaway greenhouse effect” that has caused the planet’s temperature to soar to 465°C, hot enough to melt lead. This means that Venus is even hotter than Mercury.
What is Mars like today?
The average temperature on Mars is minus 80 degrees Fahrenheit — way below freezing! Its surface is rocky, with canyons, volcanoes, dry lake beds and craters all over it. Red dust covers most of its surface. Mars has clouds and wind just like Earth.
Which planet has the most violent storms?
Extraterrestrial Hurricanes: Other Planets Have Huge Storms, Too. Close-up of Jupiter’s Great Red Spot as seen by a Voyager spacecraft. By Earth standards, Hurricane Irene is a monster storm. But it’s just a baby compared to the massive cyclones of Jupiter and Saturn.
Which planet has the most extreme seasons?
Most have four like the Earth — called Winter, Spring, Summer and Fall — but that’s where the similarities end. Extraterrestrial seasons are hardly noticeable on some planets (Venus), mindbogglingly extreme on others (Uranus) and in some cases simply impossible to define (Mercury).
What does it rain on Mars?
There is no rain on Mars because the low temperatures and pressures mean water can only exist as vapor or ice (although it may have have rained in the geologic past say scientists). Snow occasionally forms in the upper atmosphere but does not reach the ground writes Universe Today.
What is Mercury’s temperature at night?
Since Mercury is the closest planet to the Sun, spins slowly, and does not have much of an atmosphere to trap heat, its temperature varies greatly. Mercury’s temperatures can go between -279 Fahrenheit (-173 Celsius) at night to 801 Fahrenheit (427 Celsius) during the day. (This is hot enough to melt lead!)
Which planet looks brightest in the sky?
Venus
Why doesn’t Mars have active volcanoes today?
Mars Volcanoes. Mars today has no active volcanoes. Much of the heat stored inside the planet when it formed has been lost, and the outer crust of Mars is too thick to allow molten rock from deep below to reach the surface. But long ago, eruptions built enormous volcanoes and piles of thick ash.
How hot is Mars?
In winter, near the poles temperatures can get down to minus 195 degrees F (minus 125 degrees C). A summer day on Mars may get up to 70 degrees F (20 degrees C) near the equator, but at night the temperature can plummet to about minus 100 degrees F (minus 73 C).
What is temperature of the sun?
5,778 K
What is the hottest temperature on Uranus?
At the core of the planet, temperatures are believed to reach as high as 11,700 °C. Uranus is the coldest planet in our Solar System, with a lowest recorded temperature of -224°C. Despite its distance from the Sun, the largest contributing factor to its frigid nature has to do with its core.
Can life support Mars?
The confirmation that liquid water once flowed on Mars, the existence of nutrients, and the previous discovery of a past magnetic field that protected the planet from cosmic and solar radiation, together strongly suggest that Mars could have had the environmental factors to support life.
Can you live on Mars?
Human survival on Mars would require living in artificial Mars habitats with complex life-support systems. One key aspect of this would be water processing systems. Being made mainly of water, a human being would die in a matter of days without it.
Is Mars Habitable?
According to scientists, Mars exists on the outer edge of the habitable zone, a region of the Solar System where liquid water on the surface may be supported if concentrated greenhouse gases could increase the atmospheric pressure.
