The Most-Distant Solar System Object Discovered (cnn.com)

Rick Zeman writes: Astronomers in Hawaii have discovered the furthest object in our solar system, a dwarf planet aptly named "Farout." This planet is 100 times farther than Earth is from the sun (120 AU from the sun) and is thought to be composed of ice. The object is so far away that researchers estimate it probably takes more than 1,000 years to make one trip around the sun. For reference, Pluto is 34 AU away and takes about 248 years to orbit the sun. Eris, the next most distance object know, is 96 AU from the sun.

I think when you find new planets orbiting our sun at some distance our solar system is by definition expanded out to that distance.

That's a question of semantics. Voyager has left our heliosphere. This new planet is still held by the sun's gravity, so it would be part of our solar system even if it is outside the heliosphere.
