Mercury has little or no atmosphere to protect it thermally from the cold of space, nor from the heat of the sun during the day. Although the temperature can reach more than 427 °C (800 °F), this heat is rapidly radiated back into space once the area is out of the sunlight. During the night (88 earth days long), the temperature of the surface falls to -184°C (-300°F).
Gases in Earth's air, including water vapor and carbon dioxide, make a "greenhouse" effect that stops most of the heat from escaping at night. Without some greenhouse effect, Earth would also suffer extremes of temperature. Venus (which orbits between Mercury and Earth) has an atmosphere 90 times as thick as Earth's so its greenhouse effect is substantially more noticeable. The surface of Venus stays around 400 degrees even at night.
What else can I help you with?
What is the temperature like on the inner planets?
Mercury: in the day about 700K at night about 100K Venus : All the time about 735K A more interesting question you should be asking yourself right now is: Why is Venus hotter than Mercury when it is further from the sun?
Why is mercury not hotter then Venus?
Mercury is less hotter than Venus because it has a thin atmosphere and the heat that is attracted during day time goes away at night and the temperature becomes -170 degrees while Venus has a thick atmosphere and does not allow heat to pass.
Which is hotter mars or mercury?
Mercury is hotter than Mars. Mercury is the closest planet to the sun, so its proximity results in higher temperatures compared to Mars. Additionally, Mercury has an extremely thin atmosphere that cannot retain heat, causing its surface temperatures to vary greatly between day and night.
Which planet has the longest cycle of day and night of the terrestrial planets?
Mercury has the longest cycle of day and night among the terrestrial planets. A day on Mercury lasts about 176 Earth days, which is longer than a year on Mercury. This is because Mercury rotates very slowly on its axis.
What is the day and night temperature for mercury?
Bloody hot in the day and hot at night

Is Mercury or earth hotter?
When it is night on Mercury, it's colder than earth at any given time,but during the day,obviously,there is no comparison,the earth is much colder. BY THE WAY:this is coming from a 13 year old ;) but one that knows her sh*t.

Which is hotter the Moon or Pluto?
Day time on the Moon is hotter than Pluto. Night time on the moon is about as cold as Pluto, sometimes colder.
Which is hotter mars or mercury?

Where does an echidna stay at night?
They stay in their burrows at night and for the hotter part of the day.
Which planet has the longest cycle of day and night of the terrestrial planets?
Mercury has the longest cycle of day and night among the terrestrial planets. A day on Mercury lasts about 176 Earth days, which is longer than a year on Mercury. This is because Mercury rotates very slowly on its axis.
Why is it hotter at night?
It is not necessarily hotter at night. In fact, temperatures typically drop at night due to the absence of sunlight. However, in urban areas, buildings and pavement can absorb heat during the day and release it at night, causing temperatures to remain higher than in rural areas.
Which planet has the longest cycle of day and night?
The planet is Mercury. (Some people think it is Venus, but it is Mercury.)
What is the day and night temperature for mercury?
Bloody hot in the day and hot at night
What is the solution to the brain teaser regarding the day before being hotter than today?
The answer to the brain teaser "What is the day before today if two days from now will be the second day this week that will be hotter than today" is Friday. This is because if today is Friday, the day before today, which is Thursday, will be hotter than today (Friday), and two days from Friday is Sunday, which will be the second day that is hotter than Friday.
Why does mercury's surface temperature varies so much from day to night?
because mercury is extremely hot during the day and extremely cold at night
