Unbound in this context means, that the distance from the particle orbiting (e.g. earth) to its focal point (e.g. sun) is not bound and can become infinite.
In a bound orbit, this is not possible. The orbiting particle will always be closer to its focal point than a maximal radius. It can not escape to infinity.
This also works for an infalling particle, where the radius is not bounded from below and can become 0, i.e. it collides with the focus. In this case, there is no minimal radius. (technically, there is one, but it is 0).
To summarise: unbound means, either the orbiting particle escapes to infinity or collides with it's focal point at some time.

What is the difference between a bound orbit and an unbound orbit around the Sun?
An object on a bound orbit follows the same path around the Sun over and over, while an object on an unbound orbit approaches the Sun just once and then never returns.
What keeps objects in orbit in our solar system?
Gravity combined with the object's "sideways" (tangential to its orbit) motion. The Sun "wants" to pull the object towards it and the object "wants" to fly of into space. When these two things are balanced the object is in a stable orbit.
What object keeps Saturn in orbit?
Saturn is kept in orbit by the sun.
What is the period when an object travels around another object?
orbit
An object is kept in orbit by?
Gravity.

This is an orbit.

What shape describes the paths that planets follow?
The planets orbit the sun in an ellipse, like a squashed circle. The amount by which the ellipse is deformed by, from being a circle, is referred to as the eccentricity. An object with a highly eccentric orbit, such as a comet, will have a very elongated and stretched out orbit, its distance from the sun throughout its orbit will vary by a lot.

What is the path of an object as it revolves around another object in space?
If the revolving continues for more than a few revolutions, then its path is an elliptical orbit. In space, orbiting cannot take place in a circular path, and the balance point between flying off into space, crashing into the bigger object, or staying in orbit only occurs in an ellipse. It doesn't have to be much of an ellipse, either.
What is an object in orbit around the planets?
A planet in an orbit greater than any of the others.An object in orbit around a single planet is a moon or satellite of that planet.
What object keeps Saturn in orbit?
Saturn is kept in orbit by the sun.
What is path an object follows when orbiting another object?

What is the movement of an object around another object is called?
