Mercury is un-livable, because it's surface becomes extremely hot and extremely cold.
Mercury is the closest planet to the Sun, and its slow rotation gives most of the surface 88 Earth days of blistering heat followed by 88 days of incredible cold (on the side not heated by the Sun).
The climate of a planet is defined by the temperature, humidity, atmospheric pressure, wind, rainfall and many other factors. Earthhas a climate, obviously, and even Mars andVenus have atmospheres and some kind of climate. But what about the other terrestrial planet, Mercury? What kind of climate does Mercury have?
First, let's look at temperature. Temperatures on Mercury can range from 700 Kelvin (426 degrees Celsius) when you're at the equator at noon, and then dip down to 100 Kelvin (-173 degrees C) in the middle of Mercury's night.
The atmospheric pressure on Mercury is estimated to be 0.000000000002 kilograms per square centimeter. Just for comparison, the air pressure on Earth is 1.03 kilograms per square centimeter. In other words, the atmospheric pressure on Earth is 515 billion times higher than the pressure on Mercury. In fact, Mercury doesn't really have an atmosphere, it has an exosphere. This is a thin collection of particles surrounding the planet, which is regenerated by the Sun's solar wind and dust kicked up from micrometeorite impacts.
And then from here on out, there isn't much else to Mercury's climate. There is some watervapor in Mercury's "atmosphere", but it's not really possible to measure it in terms of humidity. There's no wind, apart from the steady blowing of the solar wind. There's norainfall, aerosols in the atmosphere, etc.
Mercury is really just a dry, dead world with no active climate to speak of.
We have written many stories about Mercury here on Universe Today. Here's an article about a the discovery that Mercury's core is liquid. And how Mercury is actually less like the Moon than previously believed.

We have also recorded a whole episode of Astronomy Cast that's just about planet Mercury. Listen to it here, Episode 49: Mercury.
Clima de Mercurio
Mercury has two climate
They are either really hot or really cold due to the fact that mercuryis the closest to the sun,rotates really slow and lacks a protective atmosphere
Surface has many craters and high cliffs.
Mercury has no climate since it has no substantial atmosphere.
very hot!
Hot and even more hot
Assuming "coler" is meant to be colour, the planet Mercury is dark grey.
mercury is the closest planet to the sun
craters,plains,and volcanoes. it is a dense planet and is a inner and rocky planet. it has no rings and no moons. it also has no atmosphere.
Mercury is the closest planet to the Sun and has one planet[venus] between us[Earth] and Mercury.
Hot and even more hot
The nickname for mercury is Swift Planet or quicksilver
The soil on the planet mercury is grey in color.
Assuming "coler" is meant to be colour, the planet Mercury is dark grey.
mercury is the closest planet to the sun
Mercury is the closest planet from the sun (first planet from the sun). It is roughly 36 million miles from the sun.
craters,plains,and volcanoes. it is a dense planet and is a inner and rocky planet. it has no rings and no moons. it also has no atmosphere.
Mercury is the smallest planet compared to the other ones
It is the closest planet to the sun and is over 400 degrees Celsius
There are many things that make up Mercury's planet composition. There are many different minerals and clays on Mercury's surface.
The year on the planet Mercury is very short. A year on this planet lasts 88 days compared to 365 days on Earth.
Mercury is the closest planet to the Sun and has one planet[venus] between us[Earth] and Mercury.
