Hello. Recently I was able to observe the ISS and after spending a couple minutes moving through the night sky, it disappeared very suddenly while it was still very high above the horizon. In a RE, this can be explained by the station moving into the shadow of the earth. Since it is under my understanding that in FE, the sun just moves around in circles over the surface of the earth and therefore, any satellites including the ISS would constantly be in full view of the sun. If I am correct, then the ISS would be constantly illuminated by the sun. This however is not the case and my question is how does FE explain satellites suddenly disappearing as they move through the night sky. Thank you.
