Question: can a comet hit the earth in under 50 years

maybe! various countries and scientists are tracking all the comets and meteorites as well as they can and i’m pretty sure none of those are going to hit us in the next 50 years… but there might be a dark unspotted rock out there i suppose…. BUT space is big and the earth is very small so it’s very very very unlikely that we’re going to get hit in the next 50 years…
