How to spot ISS?

ISS is a great example of international collaboration. I love watching night sky and whenever I do, I keep an on ISS.




ISS orbits around Earth at a speed of roughly 17,150 miles per hour. That means, it orbits around Earth every 92 minutes. Yes, Astronauts onboard see a sunrise every 92 minutes.

Now, if you are in the red part of the below image you can watch the ISS at night. India being center of that part has one of the best views.




You can spot the ISS using the very cool NASA webpage.

In the below example in 2 minutes window you can watch ISS appear at 10degrees about North of North-East and  it will continue till 12 degrees above East of Nort East.




There are many apps which provide the current location of ISS.
