Interesting Facts About Mercury
- Mercury has water ice and organics.
- The water ice appears younger than we would expect.
- Mercury has an atmosphere that changes with its distance to the Sun.
- Mercury’s magnetic field is different at its poles.
- Despite Mercury’s weak magnetic field, it behaves similarly to Earth’s.
What is a fact about Mercury’s atmosphere?
Mercury has a very thin atmosphere called an exosphere. It is made out of oxygen, sodium, hydrogen, helium, and potassium. Since its surface is similar to our Moon, it indicates that the small planet hasn’t been geologically active for many years. The planet is primarily made out of rocks.
Does Mercury have a good atmosphere?
Mercury has an extremely thin atmosphere which is made up of atoms blasted off its surface by the Solar wind, a constant stream of particles coming from the outer layer of the Sun. Because Mercury is so hot, these atoms quickly escape into space.

Does Mercury have ice?
Mercury is not alone in having ice on its surface, as water ice has also been discovered on the moon and on small worlds such as asteroids and comets. These locations may have variations in water deposition, however.
What is an interesting fact about Mercury the element?

Can you touch mercury with your hands?
Mercury is a very toxic or poisonous substance that people can be exposed to in several ways. If it is swallowed, like from a broken thermometer, it mostly passes through your body and very little is absorbed. If you touch it, a small amount may pass through your skin, but not usually enough to harm you.
What are 5 interesting facts about the planet Mercury?

Why doesn’t Mercury have an atmosphere?
Mercury has just 38% the gravity of Earth, this is too little to hold on to what atmosphere it has which is blown away by solar winds. However while gases escape into space they are constantly being replenished at the same time by the same solar winds, radioactive decay and dust caused by micrometeorites.
What do we know the least about mercury?
Mercury is the smallest planet in our solar system. Out of all the terrestrial planets (Mercury, Venus, Earth, Mars), we know the least about Mercury. It is only about 40% of the size of Earth. There are actually moons of other planets that are bigger than Mercury (Ganymede and Titan)!
How many days are there in a year on Mercury?
A year on Mercury is just 88 days long. One solar day (the time from noon tonoon on the planet’s surface) on Mercury lasts the equivalent of 176 Earth dayswhile the sidereal day (the time for 1 rotation in relation to a fixed point) lasts59 Earth days. Mercury is the smallest planet in the Solar System.
