Do gravity holes harbor planetary assassins?

They are the places gravity forgot. Vast regions of space, millions of kilometers across, in which celestial forces cancel out gravity and trap anything that falls into them. They sit in the Earth's orbit, one ahead of our planet, the other trailing behind. Astronomers call them Lagrangian points, L4 and L5 for short. Since the formation of the solar system, everything from dust clouds to asteroids and hidden planets may have accumulated there. Some have even speculated that alien spacecraft are watching us from the Lagrangian points, looking for signs of intelligence.

These L4 and L5 spaces have been detected at Jupiter (thousands of objects at each) and Neptune. Thus far, none have been found in Earth's, but that's mainly due to their orbital location, which puts them in the sun's glare at sunset and sunrise, respectively.

Perhaps it's in these 'holes' we'll find our missing neighbor(s)!

Every object in orbit around another object will have 5 such points. Gravity is not really "canceled" there, it is more properly called an equilibrium.

We know quite a bit about our L1 point. SOHO and ACE are orbiting it so if there were something there we would probably know about it. L2 is outside our orbit, directly opposite the sun so we could find anything there without much difficulty. STEREO will tell us about L4 and L5.

The only one we can't observe is L3 which is directly opposite the sun. Though unstable (as are L1 and L2). It does make good location for a holding pattern. "Here be dragons".

It seems it might be desirable to place satellites in each to set up a system like Iridium, always in communication and with vantage points around the entire orbital circumference.

Now that is an interesting idea.

Placing satellites at L4 and L5 (stable locations, requiring no correction) would enable a link with L3. With that link, the L3 satellite could receive and send data, it could be given commands to correct and maintain its position.

If nothing else we would be able to get real time data about what's happening on the far side of the Sun. But the exciting thing is the possibility of some serious VLA (emphasis on "very") radio telescope observations. With that kind of base line the resolution would be impressive.

Astronomical proportions, no? This would be really advantageous it would seem for all knids of observations.

We'll have L4 and L5 taken care of for as long as STEREO survives. It wouldn't be hard to place another satellite at L3 with off-the-shelf electronics/optics.

Report to NASA/JPL/AMES at once, please!
