Trojan asteroids have orbits that share the same orbital path as a planet, but are located 60 degrees ahead or behind the planet in its orbit. They are therefore in a stable configuration known as Lagrange points, specifically the L4 and L5 points.

Here's a breakdown:

* Lagrange Points: These are five specific points in a two-body system (like the Sun and a planet) where an object can maintain a stable orbit.

* L4 and L5: These points are located 60 degrees ahead and behind the planet in its orbit around the Sun.

* Trojan Asteroids: These asteroids occupy the L4 and L5 points of Jupiter's orbit.

So, to summarize, Trojan asteroids:

* Share the same orbital period as the planet they accompany.

* Are located at the L4 and L5 Lagrange points, 60 degrees ahead or behind the planet.

* Maintain a stable orbit due to the gravitational balance of the planet, the Sun, and the asteroid itself.
