According to those who do not accept the IAU's judgement on such matters - and no one is required to - Pluto.
While Pluto was declared by the IAU to no longer be a planet, many disagreed. They had - and have - that right.
Jupiter. Jupiter has a mass of 1.8986×1027 kg, 317.83 times the mass of earth. Jupiter is massive enough to be used as a reference mass for describing the mass of the other outer planets of our solar system.
Mercury is considered the smallest rocky planet in our solar system. It has a rocky core and is closest to the Sun.
Neptune is an outer planet. It is the outermost planet in the solar system.
Neptune is the outermost large planet in our solar system. However, the outermost known planet in our system, when including all classifications of planets, is Sedna, a dwarf planet.

Mercury is both the smalles inner planet, and smallest planet in our entire solar system.

The smallest and coldest planet in our solar system is Pluto. It is a dwarf planet located on the outer edges of our solar system, and its surface temperatures can drop as low as -375 degrees Fahrenheit (-225 degrees Celsius).
If by that you mean, weather its an outer or inner planet then Saturn is an outer planet...the 6th planet in our solar system.
Neptune is the outermost large planet in our solar system. However, the outermost known planet in our system, when including all classifications of planets, is Sedna, a dwarf planet.
Jupiter is an outer planet. It is one of the gas giants in our solar system and is located beyond the asteroid belt, closer to the outer reaches of the solar system.
Neptune
Chiron is a minor planet in the outer Solar System
Makemake is an asteroid/Kuiper belt object in the outer solar system.
The inner solar system is comprised of (in increasing distance from the Sun) Mercury, Venus, Earth, and Mars. The outer solar system is comprised of (same ordering) Jupiter, Saturn, Neptune, and Uranus.Pluto was downgraded to dwarf planet status in 2006, and is no longer considered a planet.
