Re: To further calms the nerves
It's not very convincing. DA14 is 45 metres across therefore is worth tracking and warning about. The one that hit Russia was 17 metres across therefore is too small to bother with. There does not seem to be a big difference to me especially given the difficulty of accurate measurement of remote space rocks.
Meanwhile the population of DA14 is cheering "yay that big planet thing didn't hit us"
