Mercury was discovered by the Ancients.
The mass of Mercury is 5% of Earth.
Mercury was the Roman version of the Greek god Hermes in astronomy mythology.
On Earth, you way a lot more than you would on Mercury because Mercury is a lot smaller than Earth and has less gravity than Earth!
If you weigh only 70 lbs. on Earth, you way only 27 lbs. on Mercury!
I wish I lived on
Mercury, I would not weigh a
lot!
Mercury shines very brightly in early morning just before the sun rises, so sometimes Mercury is called a “morning star.”
It is also called an “evening star” because of the same reason. Picture from:

Sometimes, Mercury is often visible for a short period of time right after the sun sets.
Mercury’s core covers up about 75% of the planet.

Next to Earth, Mercury is the 2nd most dense planet in our solar system.
As Mercury’s iron core cools, it shrinks causing its rocky crust to become wrinkled.

Scientists started calling Mercury’s wrinkles Lobate Scarps.
It takes Mercury 59 days to rotate, but only 88 days to circle around the sun.
On Mercury, there are 2 fewer days in a year.
