I've red, a long time ago, that only 3 celestrial bodies cast shadow on Earth : Sun, Moon and Venus. I checked it out , and it's true.(I mean for Venus
Now, if you look the figures, the magnitude of the ISS is way less than Venus' but, when you SEE the ISS, at least to my eyes, it looks, sometimes, way brighter than Venus. Hence my question : does the ISS casts shadow? I'll be hard to run the experience because,as Venus, the ISS is visible only after the Sun set or before the Sun rise which means you'll have to find the rigth day and be at the right place. If somebody can prove ISS actualy casts shadow, it'll be a (fast) MOVING shadow. Sun, Moon and Venus can't do that. The only "celestrial bodies" that could cast moving shadows would be very bright meteroits, entering vehicules from space, ... Reactions? -------------------- |
