i liked this episode alot, like all other episode.
my question is..
are there lagrange point between sun and earth only or they can be between any two bodies. like earth and moon, or earth and mars. etc

Are there plans to use L4 & L5 for a "Binocular" telescope(s). Seems like that would be capable of extreme parallaxes.

Good day,

So, given the discussion of LaGrange points, I'm guessing that the old Science Fiction chestnut about a "hidden planet" on the far side of the sun -in the exact, corresponding orbit of Earth- wouldn't be possible. The presence of another gravitational body in that position -so close to L3- would, essentially, totally re-position and "cancel out" the existing, observed L1-L5.

Would this assessment be correct?

Yours,
Dave

Dear Sir : The Soho space craft circling the Sun is at one of the Langrangian points, but when I tried to compute the point of stability, I get a different number from where SOHO actually is , the computation is s follows.

Mst x Msun = Mst x Mearth earth
——————- ————————–

D2 (distance from SOHO to sun ) d2 distnce from soho to earth
