pros.
A computerized and minimally mechanized space probe would have only a small fraction of the needs and equipment of a human housing space ship. This would save on mass and therefore fuel.
A mechanized probe has a lot less functioning parts therefore there is less that can go wrong with it.
A mechanized space probe could survive the years that it take to get to its destination. Humans tend to get bored and psychotic.
The space probe that has taken detailed photos of Mercury is the MESSENGER (MErcury Surface, Space ENvironment, GEochemistry, and Ranging) spacecraft. It orbited Mercury from 2011 to 2015 and provided valuable insights into the planet's surface and composition.
Pluto was the only planet not visited by a space mariner space probe.
The first planet to be explored by a space probe is Venus. Hope this helps. : )
Mercury
The NASA space probe Pathfinder landed on Mars in July 1997.
The first Mars space probe expedition that did not land on Mars by the US was Mariner 4, launched on November 28, 1964. It provided the first close-up images of another planet as it conducted a flyby of Mars on July 14, 1965, sending back 21 photos.
Venus was the first planet on which a space probe landed.
Pluto is one such planet that has not yet been reached by a space probe.
A planet's gravity affects the trajectory of a space probe by pulling it towards the planet, causing the probe to alter its course. The probe's speed and direction can be influenced by the planet's gravity, leading to changes in its orbit or flight path. Scientists must account for the planet's gravitational pull when planning the probe's trajectory to ensure it reaches its intended destination.

the megellan space probe was sent to venus.
Saturn
Mars
Pluto. That is now a dwarf planet. :)
the planet they are studying is Saturn.
The Mariner10 space probe and the Mercury Messenger space probe.
