Get ready to spin around and celebrate Earth's Rotation Day on January 8! This day commemorates the fact that our planet is constantly rotating on its axis, giving us day and night. It was first observed in 1851 by French astronomer Jean-Pierre Foucault, who used a pendulum to demonstrate the rotation of the Earth. Since then, this day has been a reminder of the amazing phenomenon that shapes our daily lives. So let's take a moment to appreciate and marvel at our planet's rotation, while also thinking about ways we can help keep it spinning for many more years to come.
