Can an astronaut throw a ball to the Earth? The answer is Yes, and No. Depends what you mean by hitting the Earth. First, if you throw a ball towards the Earth – yes it’s traveling that way when you throw it. So, it is natural to think that no matter how slow it is, it would get there eventually. However, we aren’t used to throwing things in orbit, and our intuitions can often lead us astray.
