Sedna is the most distant solar system object discovered so far. It is about three times farther away than Pluto currently is. Because it is so far away, scientists are not sure if it has enough mass to be classified as a dwarf planet.
Neptune.
It is the most distant object known
The most distant objects in the Solar System are probably comets. However, as that region of space has not been explored, there could be anything out there, even another planet.
No, there are a lot of objects more distant than Pluto. Sedna, probably a dwarf planet, has an aphelion of about 31 times the distance of Neptune. Long period comets are thought to be even further out. The Oort cloud, which is part of the solar system, lies at its edge at 50,000 AUs distant.

The sun, Sol. (The sun, or central star of a system, is usually the most massive object in a solar system.)
The Sun is the most massive object in our Solar System, followed by Jupiter.
No, Earth is not the most distant planet from the sun. Neptune holds the title for being the most distant planet in our solar system.
