Mercury and the Sun.
Mercury is what we call a “rocky planet” or a “terrestrial planet.”

You may know him better as Dr. Seuss!
A Day on Mercury is Very Long
Have you ever wondered how long a day is on Mercury?
Well, hold onto your space helmets, kids!
A day on Mercury is about 176 Earth days (that’s one full day-night cycle).
This is because, compared to Earth, Mercury spins super slowly on its axis.
Mercury is Hot and Cold
Even though Mercury is close to the Sun, its temperatures vary to the extreme.
During the day when the Sun is shining on it, it gets hotter than a summer day on Earth.
But at night, when the Sun goes down, it gets really cold like in the winter.
In fact, some of Mercury’s craters even have ice where there is little to no sunlight!
There is No Atmosphere on Mercury
Think of the atmosphere as a big, invisible blanket of air that keeps the planet cozy.
Well, unlike Earth, Mercury doesn’t really have one.
Because there is no atmosphere, the surface of Mercury is quite unique.
There is no wind, no rain, and no snow.
Mercury doesn’t have weather of any kind!

Can you imagine seeing a gigantic, colorful sunrise or sunset that fills the sky?
A Year on Mercury is Quick
Mercury speeds around the Sun faster than any other planet!
In fact, it only takes 88 Earth days for Mercury to go around the sun.

Then between 2011 and 2015, Messenger was sent to orbit the planet.
Messenger got an up-close look, took a lot of pictures, and recorded information.
This is how we learned about Mercury’s surface, its craters, and even its magnetic field!
