The Moon is the biggest and brightest object that one can spot on the night sky. It appears quite large because it is the closest celestial body to Earth.
The equatorial radius of the Moon is around 1737 kilometres and the equatorial diameter is about 3472 kilometres. It is almost one-fourth the size of Earth. You can roughly fit in four moons inside the Earth. The Moon’s surface is as big as North and South America put together. According to NASA, “if Earth was the size of a nickel, the Moon would be about as big as a coffee bean.”
The Moon is not a perfect sphere, just like the Earth. It is slightly flattened towards the poles. The diameter of the Moon from pole to pole is lesser than its equatorial diameter.
