I saw a asteroid might hit earth in october can you please tell me any info?

IF its trajectory changes drastically from current parameters, FT3 could hit the Earth.
But there is no reason for it to change course.

Nothing that hasn't happened before

Just another NEO. No impact.

details on near Earth asteroids are carried (with a lot of other stuff) on spaceweather.com but you'll be disappointed to know there are NO asteroids known with more than a tiny chance of hitting Earth in the next few centuries.

An asteroid can hit earth tomorrow. If it happens, it happens. If we can stop it, we will stop it.
