Baseball

Mercury, the planet closest to the Sun, is the second smallest planet in the solar system, Pluto being the smallest. If Earth were the size of a baseball Mercury would be a golf ball.

Froid

Because Mercury is so close to the Sun, temperatures, during the day, can reach a scorching 425°C hum! You could bake a cake at this temperature! And since this planet has hardly any atmosphere to keep in the heat, temperatures at night can drop to a frigid 183°C below zero! Because of its very thin atmosphere, humans would not be able to live on Mercury.

Soleil

Another Mercurian peculiarity, is the planet’s strange orbit and rotation path; Mercury rotates three times in two of its years. What this means is that the sun rises, gradually getting bigger as it moves toward the zenith (highest point in the sky), then the sun stops, briefly reverse its course, stops again, and resumes its path towards the horizon while appearing to get smaller.

Mercury circles the Sun every 88 days, speeding through space at nearly 50 kilometres (km) per second; a car travels 50 km per hour in most city streets, so you can imagine how fast Mercury is rotating!

How heavy would you be on Mercury?

Balance

If you weigh 34 kilograms (kg) (75 pounds (lb.)) on Earth, you would weigh 9 kg (21 lb.) on Mercury. To calculate your weight, all you have to do is multiply your weight (kg or lb.) by 0.284.

How old would you be on Mercury?
