Duh, distance from center of earth is 42000km ( add, don't subtract dummy )

So it is 2TAN 6378/42000 = about 17 degrees.

I can't believe I couldn't Google this, so

Earth Radius at equator = 6378 km GeoSynch orbit = aprox 36000 km above sea level or aprox 30,0000 from center of earth

Angle = 2TAN 6378/30000 = aprox 24 degrees.

Hi All,

I have a couple of questions, How big is the earth from a geosyncronous (sp?) orbit.

Like the Moon from Earth is roughly 1/2 a degree.

What is the earth from a geo orbit? anyone know?
