Trojan asteroid
Trojan asteroid refers to asteroids orbiting in the 4th and 5th Lagrange points of major planets in the Solar System. Currently there are six planets known to have trojans:
- Venus trojans (1)
- Earth trojans (1)
- Mars trojans (7)
- Jupiter trojans (6000+)
- Uranus trojans (1)
- Neptune trojans (18)
It is possible Mercury and Saturn have trojan asteroids, but none have been discovered so far due to; Mercury's close proximity to the Sun hindering the observation of such objects, and Saturn's proximity to Jupiter throwing possible would-be trojans out of a stable orbit with Saturn.

So here by artificial means the same kind of synchronous grouping had been achieved as had been formed since millennia in the Earthly solar system between Jupiter and its so-called Trojan asteroid group.
