Neil deGrasse Tyson Explains the Lagrange Points

What’s a Lagrange point? On this explainer, Neil deGrasse Tyson and comic co-host Chuck Nice explain orbits, satellites, and Lagrange points in space. Big thanks to today s sponsor, Henson Shaving.

We dive into the physics of how objects in orbit are actually falling. You’ll learn about these regions of stability and how the moon’s orbit help create them. How many are there? How do we use Lagrange points? Are there differences between them? We discuss where we put the James Webb Space Telescope and why it s important. Where’s the Discover satellite? We break down Lagrangian placements in space and the Trojan and Greek asteroids of Jupiter. All that and more on another StarTalk explainer!
