  The moon measures about 2160 miles (3476 km) across. The distance is about one fourth the diameter of the Earth, and 400 times smaller than that of the sun.
Now that weâre thinking about horizons, hereâs another cool thing to think about. The horizon is three miles away on earth. But elsewhere in the solar system itâs closer or farther, depending on the size of the body youâre standing on! Take the moon. The moon is two thousand, one hundred and sixty miles in diameter, only about one quarter the size of the earth. So the curvature at its surface is much more noticeable, and the horizon is much closer. Itâs only about 1.5 miles away.
