Value of R:

Question 1
The ISS sits 420km from the Earth's surface. Since my R-value of 700 the astronauts would
be able to identify objects 600m in size - 420,00 0m/700=60 0m.
Rogers Stadium is 200 meters wide, so the astronauts will not be able to make out the field
Question 2:
The Great Wall is observable in space depending on the conditions. The Great Wall stretches
across a vast portion of northern China making it visible at certain times from space. Here is a
photo provided by the European Space Agency.

Questions 3:
Distance from Earth to the moon: 384,401km or 384,402,000 m
R = 700
384,401,000 m/700 = 497,715 m
A feature would need to be 497,715 meters in length to be visible from the earth
Question 4:
Yes, Lake Ontario would in fact be visible from the moon with the unaided eye, as it has an
area of 19,000km. An object or distinct surface on Earth only needs to be 500km in size to be
visible from the moon/space.
