# Are there Trojan or Hilda asteroids locked in Earth's orbit? [closed]

Jupiter has many Trojan asteroids located at Lagrangian points L4 and L5 and Hilda asteroids dispersed between points L3, L4, and L5.

Does the Earth have similar asteroids? If so, how many?

I don't see the physics in this, but I'm almost positive it would be a perfect fit on Astronomy. Since it's a beta site, I can't (shouldn't) migrate the question, but I'd suggest that you go re-ask it there (check and see if it's already been asked, though). –  David Z Sep 9 '11 at 19:40
The first Earth Trojan was announced a few months ago: en.wikipedia.org/wiki/2010_TK7 Its orbital motion is still not fully understood, and may be chaotic. –  felix Sep 10 '11 at 0:02
