When we can see India from space at the same time we are unable to see America why?

The latitude and longitude of India are 20' North and 77' East respectively. The latitude and longitude of United States of America is 38° 00' N and 97° 00' W respectively.

We can only see one country at a time because,

1. The earth is the spherical and only side of a sphere is visible at a time.

2. India & America are at two sides of the earth so only one of these places is visible at a time.

Therefore, when India is visible, America isn’t.
