Two
It is a SPECIAL form of ellipse. In an ellipse the centre and the two foci are at separate points on one axid. In a circle the centre and the two foci are ALL at the circle centre.

An ellipse has 2 foci. They are inside the ellipse, but they can't be said to be at the centre, as an ellipse doesn't have one.
The two centers of an ellipse are called the foci (singular: focus). The foci are two distinct points along the major axis of the ellipse, and the sum of the distances from any point on the ellipse to these two foci is constant. Additionally, the center of the ellipse, which is the midpoint between the foci, is another important point but is distinct from the foci themselves.
