Starship Asterisk*

Newbee here, but...with a question:

Telesto orbits Saturn always just ahead of the much larger moon Tethys

This is an ordinary troyan-system: Saturn-Thetys-Telesto, I assume.
What is the role of te Sun in view of the stability of this system?

Thanks for any hint or answer

Don't know but the moon looks like a big chunk of ice to me.

Since we are looking at several more than 3 bodies in this situation, I don't really think that it can be considered as a 'trojan' system at all, let alone an 'ordinary' one. Given relative proximities and masses, the integrated sum of the gravitational effects of the 'local' components (Saturn, accretion disk, all moons) probably far outweighs the impact of Sol in determining stability.
