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. WebDec 21, 2024 · For example, you can analyze Earth's elliptical orbit. The semi-major axis of Earth's orbit is a = 1 a u a = 1\ \rm au a = 1 au (1 au is one astronomical unit which is an average distance between the Earth and the Sun), and the semi-minor axis of Earth's orbit is b ≈ 0.99986 a u b \approx 0.99986\ \rm au b ≈ 0.99986 au. 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). list of metaphors for writing
