We hear it everyday - fearmongers stating that if an asteroid hit the earth it would kill all if not most life on the planet. In all seriousness - would a 1 mile wide asteroid or meteor really have that much of an impact striking our 8000+ mile diameter planet?

Today my son came home from school, He is in middle school...Anyway, he told me that his teacher made all the student's sit down and he told them he wanted to tell them somthing he found out before he started class. Now he told the student's that there was an asteroid discovered that is predicted to collide with earth or the moon in the year 2038...What I want to know is that has anyone else heard this too??? My son came home scared to death after he told them that, I really didn't know what to tell him... But I told him if that was the true facts then we would've heard about it on the news or internet... Is this true or not??
