When will a shooting star come?
There is no way to predict exactly where or when you will see a shooting star. These are completely random. “Shooting stars” are actually meteors. There was a “meteor shower” this week, but I think it is over. A meteor shower is when the earth passes through the tail of a comet. This causes LOTS of shooting stars (meteors). But EXACTLY when and where you will see one is unpredictable.
Never. There is no such thing. This is Astronomy, not medieval myth. Stars are suns. Meteors are mainly small particles. I just wish there was more education in schools about space – we live in the space age, after all. The term shooting star should have died out as soon as somebody discovered that they had nothing whatsoever to do with stars, which would probably have been in the 16th or 17th centuries. OK, to be more helpful. If you have the patience, and can go out to a very dark place (probably need an adult with you, as I suspect you are a child), you can see meteors on any night. The trouble is that people live in cities, and the skies are flooded out with artificial light. Some cities are so big and bright that you need to get at least 50 miles from them to see a good sky.
