The maximum number of tangents that can be drawn to a circle from a point outside the circle is _____.

When a point is outside a circle, the line connecting the point and the center of the circle will intersect the circle at two distinct points. These are the points of tangency for the two tangents that can be drawn from the point to the circle.

Therefore, the maximum number of tangents that can be drawn to a circle from a point outside the circle is 2.
