People have been saying this system is a serious threat to Earth. It's closest will bring it only 3,300 Light Years Away. But, It could be a threat. However, I'm not sure whether it really does. Although I read about it on Wikipedia, I'm still not convinced. Does anyone currently know the mass of the system and mass loss for each pulse, as well as orbital decay of the system? I want to find a specific location and date for this event.
