Space probe detects a planet with a double sunset

What i mean is that don't they get closer to each other such that they will collide?

Yes, but it's a rare occurrence and only happens to Neutron stars. The stars in this topic aren't Neutron stars.

Another question, whats the speed of rotation of the two stars? would it be noticeable in the naked eye from the planet?

Rotation or revolution (around the barycenter)?

The only significant thing to be noticed by an ordinary person on that planet would be the rising and setting of two suns.

If I may ask you, can you even detect, based from just looking at the moon, that the moon is indeed revolving around the earth? All that people see is the moon rising and setting--the actual revolution of the moon around the earth is not noticeable. The reason people notice the rising and setting of objects in the sky more, is because we are more attuned to the obvious rotation of the earth.

So from that alone, you can easily realize that you won't really detect the revolution of those two stars around each other, unless you systematically plot their positions in the sky each day, at the SAME TIME, and show the progression as each day passes. This is similar to the procedure in creating an analemma.
