Or in simpler terms, positions in space where objects can float motionless relative to the defining bodies. The L<sub>1</sub>, L<sub>2</sub>, and L<sub>3</sub> points are unstable, as any drifting off the point (e.g. due to the gravity of other bodies) might quickly increase the tendency to depart the area. However, there are quasi-stable halo orbits around these points, like the one used by the James Webb telescope. The L<sub>4</sub> and L<sub>5</sub> points can actually retain objects stably over long periods, resulting in the Sun-Jupiter L<sub>4</sub> and L<sub>5</sub> points capturing the {{w|Trojan (celestial_body)|Trojan Asteroids}}. |
− | There are five traditional Lagrange points. Two form equilateral triangles with the two massive objects (in this case the Earth and the Sun), and three more are collinear with the massive objects. | + | There are five traditional Lagrange points. Two form equilateral triangles with the two massive objects (in this case the Earth and the Sun), and three more are collinear with the massive objects. Randall claims that a sixth Lagrange point has been discovered outside of {{w|Cleveland}}, {{w|Ohio}}. This is pretty obviously farcical, as this would be part of the Earth and thus not gravitationally balanced between Earth and the Sun, and the joke [https://tvtropes.org/pmwiki/pmwiki.php/Main/PlaceWorseThanDeath plays on Cleveland's reputation as a strange place]. The joke is that there is a different type of place named Lagrange: {{w|LaGrange,_Ohio|Lagrange, OH}} is a small (population 2,103) village outside Cleveland ([https://www.google.com/maps/place/Lagrange,+OH+44050/ map].) |
− | + | The title text mentions {{w|Akron}} and {{w|Toledo,_Ohio|Toledo}}, two other large cities in Ohio. It says that their gravitational influence is the reason why orbits around the Cleveland L6 are unstable. Trying to orbit around a point on the ground would, of course, run into much more serious problems. | |
