Lagrange points are places around a planet where the pull of its gravity, the Sun's gravity and the motion of the orbit are balanced. Things at these points take very little energy to stay in place.

NASA’s Dr. Adriana Ocampo has more. <br /><br />Learn more about Lagrange Points: <a href="https://go.nasa.gov/3jzTNti" target="_blank" rel="nofollow">https://go.nasa.gov/3jzTNti</a><br />All about the Lucy mission: nasa.gov/lucy <br />All about the James Webb Space Telescope: <a href="https://webb.nasa.gov/" target="_blank" rel="nofollow">https://webb.nasa.gov/</a><br /><br />Credits: NASA<br />Producer: Scott Bednar<br />Producer/Editor: Jessica Wilde<br />...<br /><a href="https://www.youtube.com/watch?v=fTVN19h4nMg" target="_blank" rel="nofollow">https://www.youtube.com/watch?v=fTVN19h4nMg</a>
