We just learned about ISS - International Space Station.
We know that to remember the eight planets in our solar system we can remember the words:
My very educated mother just served us nachos.
The My in that sentence is for the planet Mercury.
(from: wikipedia - mercury (planet)
Mercury is the closest planet to the sun,
and it's also the smallest of all the eight planets.
Earth orbits around the sun every year, which is 365 days.
Mercury's orbit or year is only 88 days!
The planet has very strange days too.
It takes two whole Mercury years for it to finish one whole day and night.
That means it's daytime and sunny for a whole 88 days (3 months!)
and then totally dark for another 88 days.
