Sun and Moon

The Moon and the Sun are the brightest astronomical objects of our sky, but they are very different from each other.

The Sun is our nearest star: a large  of 1.4 million kilometers furnace that emits every second the energy of thousands of billions of lightbulbs.

The Moon, on the other hand, is our only natural satellite; just 384 thousand kilometers away, is made of rocks and it's four times smaller than out planet.
