Why is Mercury not the hottest planet?
Why is Mercury not the hottest planet?
(But Mercury is not the hottest planet in the solar system. The hottest planet is Venus.) On its dark side, Mercury gets very cold because it has almost no atmosphere to hold in heat and keep the surface warm.
Why Venus is hottest and not Mercury?
Venus has a thick, toxic atmosphere filled with carbon dioxide and it’s perpetually shrouded in thick, yellowish clouds of sulfuric acid that trap heat, causing a runaway greenhouse effect. It’s the hottest planet in our solar system, even though Mercury is closer to the Sun.
Is Mercury the hottest planet in the world?
Mercury is very close to the Sun, and hence, is the hottest planet in the solar system. Its temperature goes above 400∘C.
Which is the hottest planet in the solar system in hindi?
४. यह सबसे गर्म ग्रह है (hottest planet) —लोग बुध को सबसे गर्म ग्रह मानने की गलती कर देते हैं क्योंकि वह सूर्य के सबसे नजदीक है.
Why is Mercury the coldest?
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 in permanent shadows.

Which planet is hottest and why?
Venus is the exception, as its proximity to the Sun, and its dense atmosphere make it our solar system’s hottest planet. The mean temperatures of planets in our solar system are: Mercury – 333°F (167°C) Venus – 867°F (464°C)
What is hottest place on Earth?
But with its “consistently hot footprint over a large area,” says Mildrexler, who was not involved in the present study, “the Lut Desert has really emerged as the hottest place on Earth.”
Which planet is coldest?
Uranus holds the record for the coldest temperature ever measured in the Solar System: a very chilly -224℃. The temperature on Neptune is still very cold, of course – usually around -214℃ – but Uranus beats that. The reason why Uranus is so cold is nothing to do with its distance from the Sun.
Why is Mercury so cold at night?
Mercury rotates very slowly, so its night side spends a consecutively long time in the dark, shielded from the Sun; during those times, it gets down to just 100 Kelvin (−173 °C / −280 °F). That low temperature is incredibly cold, and far colder than any known naturally occurring temperatures here on Earth.
How does Mercury not burn up?
It is made of rocky materials that have melting points above about 600℃. So while Mercury is indeed very hot, it is not hot enough to melt. And certainly not hot enough to boil or turn into gas.
Which is hotter Mercury or Mars?
Mars is reddish color and some people might have guessed that Mars is the hottest planet in the solar system. But just because it’s red, doesn’t make it the hottest. Mercury is the planet that is closest to the sun and therefore gets more direct heat, but even it isn’t the hottest.
What are the 4 hottest planets?
| Name of Planets (Hottest to Coldest) | Mean Temperature (Degree Celsius) |
|---|---|

| 2. Mercury | (430°C) during the day, (-180°C) at night |
| 3. Earth | 16°C |
| 4. Mars | -28°C |

What is the 2 hottest planet in the solar system?
2. Mercury: The average temperature of Mercury is 167 degree Celsius. It is the first nearest planet from the Sun and the second hottest planet in the solar system.
Which star is hottest than Sun?
The hottest one measures ~210,000 K; the hottest known star. The Wolf-Rayet star WR 102 is the hottest star known, at 210,000 K.
Why is Mercury hot but not too hot for ice?
The answer lies in Mercury’s lack of atmosphere. Without an atmosphere, heat is not conducted to the parts of the planet that aren’t getting direct solar radiation. The side of Mercury that doesn’t face the sun has a temperature of 300 degrees below zero. The abundance of ice can be found in craters at Mercury’s poles.
Why is Mars hotter than Mercury?
Mars is reddish color and some people might have guessed that Mars is the hottest planet in the solar system. But just because it’s red, doesn’t make it the hottest. Mercury is the planet that is closest to the sun and therefore gets more direct heat, but even it isn’t the hottest.
Which planet is the hottest planet and why?
- Venus is the hottest planet even though Mercury is the closest planet to the Sun. …
- Thus the sunlight gets trapped by these gases giving rise to the greenhouse effect.
- The greenhouse effect increases the temperature of Venus making it the hottest planet in the solar system.
