How big are the L4/L5 Moon-Earth Lagrange Points?

Question

How large are the L4/L5 Moon-Earth lagrange points in terms of volume, or length and width?

If you were to build space stations there, would there be room for many of them, or just one?

Answer 1

I cant recall who it is I am quoting, but someone said "there is no THERE, there", when refering to the Lagrangian points.  Its just a location within empty space.  There really isnt anything there to measure.

Answer 2

They're POINTS.  If you wanted several objects there, they would need to orbit around the L4/L5 point.  These orbits could be huge, many times larger than near-earth orbits.  As a quick guess, I would say the orbits could by as large as 500,000 km by 100,000 km.  The orbit shape is quite odd, sort of like a cross-section of a long kidney bean.

A lot of habitat cylinders, 50 km long by 10 km circular, could share orbits around L4 or L5.
