We cannot leave our solar system until we figure out how to travel at much higher speeds than we can now. Even if we could travel at 1/2 of light speed, it would still take 8 years to get to the nearest star. The crew would have very little to do during the voyage. And, they'd have to carry supplies for the 16-year round trip. The ship would be enormous -- certainly larger than anything we have ever built.
Until we can find a way to travel at speeds faster than light, we will not be able to visit other star systems.

With rockets. If you count the Moon as another world, 12 men have already been there. In the future we will certainly be able to send people to Mars with rockets, and everybody considers Mars another world.
Now if you are talking about a habitable world, with good air and water like Earth, that is another matter. We do not know of any such other worlds, yet. But they probably do exist in orbit around other stars. At this time we have no way to go there. Certainly rockets are totally inadequate to the task.

I assume you mean TO other worlds? And those outside of our Solar System? Space ships traveling at a significant fraction of light. Folding space. Just slow travel with occupant's great great great grand children reaching there.
