> Glaser had noticed that a satellite in geosynchronous Earth orbit (GEO), 35,786 kilometers above the equator, would pass through Earth's shadow for only a few minutes each year.

The article addresses this. To my mind 4 minutes per year is equivalent to the parent’s layspeak “no night” comment.

4 minutes??? Not even close. Each eclipse varies from a few seconds for the first one to practically an hour in the middle, then gets shorter again, over roughly 30 eclipses each season (2 per year)
