Mercury, the Extreme Little Planet
Lecture no. 2 from the course: A Field Guide to the Planets
Taught by Professor Sabine Stanley | 30 min | Categories: The Great Courses Plus Online Science Course
Mercury is a planet of many solar system extremes—smallest planet, closest to the Sun, shortest year, most elliptical orbit, smallest axis tilt, and largest fraction of iron. Learn how these characteristics and others have resulted in a planet where the Sun sometimes moves backwards across the sky, where water ice has been found at the poles, and a magnetic field that offers more protection than Mars’.
