About a year ago I discovered the golden ellipse, which has many interesting properties
It is an ellipse, the ratio between its large diameter and the distance between the two foci is equal to $φ$
$φ=\frac{\sqrt{5}+1}{2}$
First, the ratio between the large diameter and the small diameter is equal to the square root of the golden ratio
$\frac{a}{b}=\sqrt{φ}$
Secondly, the foci of the golden ellipse are located in the middle of two opposite sides of the square centered at the center of the ellipse, whose vertices belong to the ellipse.
Thirdly, the ratio between the small diameter and the side of the square is equal to the square root of the golden ratio
Fourth, the line connecting the focus of a golden ellipse and its astigmatic peak is perpendicular to the line connecting that astigmatic peak and the peak. The focal point farthest from the taken focus
Fifthly, if a square is drawn whose sides touch a golden ellipse, the tangent points will form the vertices of a golden rectangle.
Sixthly, if we determine its four points of intersection with the accompanying hyperbola, we will form a rectangle with the ratio between its dimensions equal $\sqrt{2}$
My question is, can the golden ellipse be considered a new exclusive discovery or is it already known?
