Lagrange Points

If you like physics and astronomy, check out my new improved
webpage on "Lagrange points" - those orbits where a small third
body can stay in equilibrium rotating along with two more massive
ones:

http://math.ucr.edu/home/baez/langrange.html

Watch a movie of Trojan asteroids, read about the rare Mars
Trojans and the one known Neptune Trojan, see a movie of the
crazy horseshoe-shaped orbit of the asteroid 3753 Cruithne,
read about the search for alien spacecraft at the earth-moon
Lagrange points, and learn what was *found* at these Lagrange
points! Read about the mysterious missing extra moons of the
Earth: Lilith and Kleinchen! There's some nice math here, too:
Neil Cornish's updated version of Lagrange's proof that orbits
at L4 and L5 are stable.

^^^^^^^^^
That should be lagrange, of course.

Nice site.

To those who would just click on this (like I did), should note that
"langrange" should be replaced by "lagrange".

The ohnosecond is that exquisitely small time interval between
clicking "send" and seeing the dreadful error.

Hang in there, John. It isn't serious until you spend two hours in
Starbucks, walk out, see another Starbucks across the street, and
decide that a cup of joe is just what you need.

Respected Sir,
Gravity, electrostatic and magnetic fields exert forces spatially by
the same Inverse Squared Law. We can see lines of magnetic force using
iron filings. Are there similar demonstrative physics experiments of
moving poles or charges that simulate gravity, convincingly showing
relative locations of stable points L4 and L5 among motions of the
three bodies? It may perhaps be more instructive than fictitious
computer games and animations.

Except for magnetism.

There are no lines of magnetic force. You are viewing an artifact.

moving poles or charges that simulate gravity, convincingly showing
