If there was a huge meteorite hurtling towards earth that would cause significant damage to society or completely wipe out civilization, would astronomers tell us ahead of time?

Thank you!

Aww, I did a 2 year stint at a Regal. I saw an usher break his hand after having been goaded and verbally abused by the IMAX projectionist for years. I saw a poo so giant that it crested the water and would not flush. I saw countless barfs. I've been accused of ruining marriages because the polar express sold out. I've narrowly dodged a riot. I've extracted an insane old lady from the nacho cheese dispenser. I learned that you get the most stars for hope if you ask people to donate a dollar "to little sick kids." Those were some fun, weird times.
