Why does an object traveling in a circle at a constant speed always accelerate?

Because "acceleration" doesn't mean "speeding up". It means any change in the speed or direction of motion.
An airplane speeding up, a bicycle slowing down, and a car going around a curve, are all doing accelerated motion.
A circle has no straight parts, so an object traveling in a circle is always changing its direction. That means accelerated motion, even if its speed doesn't change..

I'm not sure but I believe it is momentum, when an object keeps moving and keeps Its speed

An object moving in a circle at constant speed always accelerates because its velocity is continuously changing direction. This change in direction constitutes an acceleration known as centripetal acceleration, which points towards the center of the circle. The object experiences this acceleration as a result of the need to keep it moving in a curved path rather than flying off in a straight line.
