Technically a satellite is something in orbit around a planet, so there cannot be any satellites ON Mercury. I will assume you mean satillites in orbit around Mercury. Mariner 10 was the first probe sent to Mercury, however it orbited the sun (i.e. was not technically a satellite of Mercury) however it's prime purpose was to observe Mercury. The probe MESSENGER and the two probes from the BepiColombo mission are currently the only satellites orbiting Mercury.
Saturn has 82 known moons, with the largest being Titan.
