In geometry, a Cassini oval is a quartic plane curve defined as the locus of points in the plane such that the product of the distances to two fixed points (foci) is constant. This may be contrasted with an ellipse, for which the sum of the distances is constant, rather than the product. Cassini ovals are the special case of polynomial lemniscates when the polynomial used has degree 2. Cassini ovals are named after the astronomer Giovanni Domenico Cassini who studied them in the late 17th century. Cassini believed that the Sun traveled around the Earth on one of these ovals, with the Earth at one focus of the oval.Other names include Cassinian ovals, Cassinian curves and ovals of Cassini.

Teach Astronomy - Great Red Spot
http://www.teachastronomy.com/ The most famous and dramatic feature on any of the giant planets is Jupiter's great red spot. This huge oval storm has existed for at least 330 years since it was reported by Cassini in 1665. It may of course have existed before the invention of the telesco

What are four types of polygons
👉 Learn about polygons and how to classify them. A polygon is a plane shape bounded by a finite chain of straight lines. A polygon can be concave or convex and it can also be regular or irregular. A concave polygon is a polygon in which at least one of its interior angles is greater than 1
