homework and exercises - How much of the sky is visible from a particular location?


From a particular point how much of the sky can be observed. For simplicity sake let us assume the particular point is the head of a 6 foot tall man floating in the middle of the ocean with no visible barriers between him and the horizon. If he stays in exactly the same location being able to turn 360 degrees how much of the sky is visible?


Would we calculate the circumference of the circle with the distance to the horizon as the radius? The surface area of a portion of a sphere?


Taking it further what percentage of the total sky can be seen at any given time. The answer above divided by the total surface area of earths atmosphere?
