Question

I know there is no comet going to hit earth in 2029 or 2034 but i wanted to know how big this comet is thats gonna fly by us?

Answer 1

99942 Apophis.

It's about a quarter mile across.  (And it's not a comet; it's a small asteroid or large meteoroid).  That's big enough to do major damage and properly placed, could kill millions of people.  But it's not big enough to be a "planet killer."

Fortunately it is not on a collision course, and this is known to a high degree of confidence.

Answer 2

Don't worry by time it's here we will learn to deal with it like blow it up.
