stupid job

Trying to explain what a Lagrangian point is to lay audience, in a limited amount of space, is a giant pain in my ass.

Ooh! A challenge!

"Five places where a satellite can sit within the Earth's and Moon's gravity and not be pulled out of position by either". Unless that's a bit too lay....

Actually, that's pretty good. Although I think that the Earth and Sun's gravitational components trumps that of the Moon.

see this graphic:

Now just have to tweak the sentence so it's not in the passive voice. :)

Surely any two-body system has 5 Lagrange points? So there will be Earth-Moon and Earth-Sun Lagrange points.

Will you be mentioning the Trojan asteroids?

This story is specifically about the Gaia mission, so no asteroids will be in the illustration. Alas.

Earth has a Trojan asteroid, according to Wiki (at the L4 point)

Did the audience at least appreciate the knowledge that you were giving them? Or was this not that type of audience?
