Theoretically, the Exosphere extends out to around 190,000 km (120,00 miles) from the surface of the earth, which is about halfway to the moon. This is where the solar radiation effects on hydrogen atoms overwhelms the gravitational pull on them by earth. The observable Exosphere is the `Geocorona`, which extends out to around 100,000km or 62,000 miles
