Talk:List of objects at Lagrangian points

From Wikipedia, the free encyclopedia

Why do the "dust clouds" link in the L4 and L5 sections go to an article about terrestrial weather phenomenon?

[edit] Trojan points vs Trojan asteroids

I just removed references to Asteroids in L4 or L5 of, say, Neptune/Sun as Trojan Asteroids. I think Trojan Asteroids are only objects in L4 or L5 of Jupiter/Sun. I think it's OK to refer to any L4 or L5 point as a Trojan Point, but that's for the Lagrangian point article.

It may be acceptable to refer to an "Asteroid in a Trojan point of PlanetXYZ-Sun" as "Trojan Asteroid of PlanetXYZ".

[edit] Exact position of L4, L5

In Earth-Sun Lagrangian points, under L4 and L5, the page has "located in the Earth's orbit".

That is not exactly true; the points are just outside Earth's orbit.

L4 & L5 are 60° from the secondary as seen from the centre of the primary; the four distances of L4 & L5 from the centres of the two massive bodies are all equal to the separation of those centres. But the secondary does not orbit the primary's centre; it orbits the barycentre. The primary and secondary orbital radii add up to the separation of their centres.

[edit] Nomenclature

I think that, when describing a set of Lagrange points by naming the corresponding two massive bodies, always to refer to those bodies in order of size.

So - Sun-Earth, Sun-Mars, Sun-Jupiter, Sun-Neptune (alternatively, reverse the others).
