Myths of Orbital Motion

Lecture no. 6 from the course: Understanding the Misconceptions of Science

Myths of Orbital Motion

Taught by Professor Don Lincoln | 31 min | Categories: The Great Courses Plus Online Science Course

In this lecture, revisit some of the common misconceptions we have about how the universe works, with a focus on our solar system. Two myths you’ll bust: that the orbits of planets are all fixed ellipses and that astronauts on the International Space Station live in zero gravity.

Interesting lecture, once again. At the time of writing (2019-Jul-14) there's a substantial blunder in the animated graphics: the orbiting of Sun and Jupiter (or Earth) around their common center of gravity is depicted so that they are both at the *same* side from it. They should be orbiting at the opposing sides around the center of gravity. In the Guidebook, this is illustrated correctly, but even there the distance of Sun's surface from center of gravity (40 000 km) is incorrectly marked between Jupiter and Sun.
