WebHe is also estimated the AU to be 10,000 times Earth's radius, whereas the actual value is about 23,000. Eratosthenes, a Greek mathematician who lived from 276 BCE to 194 BCE, calculated the AU to be roughly 150,000,000 kilometers. This was amazingly accurate. Earth radius (denoted as R🜨 or ) is the distance from the center of Earth to a point on or near its surface. Approximating the figure of Earth by an Earth spheroid, the radius ranges from a maximum of nearly 6,378 km (3,963 mi) (equatorial radius, denoted a) to a minimum of nearly 6,357 km (3,950 mi) (polar radius, denoted b). WebDec 21, 2024 · For example, you can analyze Earth's elliptical orbit.

Earth's orbit around the Sun is an ellipse. The semi-major axis of this elliptic orbit is defined to be half of the straight line segment that joins the perihelion and aphelion. The centre of the Sun lies on this straight line segment, but not at its midpoint.
