Best Answer: It depends on your height above the surface of the water. where h is the height above ground or sea level (in meters) of the eye of the observer. For an observer standing at sea level with h = 1.70 metres (5 ft 7 in) (average eye-level height), the horizon is at a distance of 4.7 kilometres (2.9 mi).
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.
