In an ellipse, geometrically speaking, there are 2 foci - Am I correct?

The Sun is at one "side" of the ellipse, it is one foci in the ellipse - Am I correct?

Our orbit around the Sun is not a circle because we do not travel at equal distances away from the Sun (Our perihelion and aphelion points are proof of this) - Am I correct?

So if our orbit is not circular but rather elliptical, then what is the other focus of the ellipse? Is our orbit a true ellipse?

I hope this sheds light on what I was asking
