PLuto is not a planet anymore because they could not find enough information on it and can't really tell things about that you don't already know.

Mercury is not a jovian planet because all planets after Jupiter and Jupiter are all jovian planets. So Jupiter, Saturn , Uranus , Neptune and the poor old Pluto that was booted from the planets are all jovian.
jovian
Jovian planets have rings because their strong gravitational forces can capture and maintain orbiting particles and debris that form the rings. This is due to their larger size and mass compared to terrestrial planets. The rings around Jovian planets are made up of rock, ice, and dust particles that orbit around the planet in thin bands.
Apparently in the solar system, there's only one dwarf planet which is Pluto. The remaining 8 planets are not dwarf planets and can be divided into Terrestrial planets and jovian planets. Mercury, Venus, Earth and mars are all terrestrial planets while Jupiter, Saturn and uranus are known as Jovian planets. The term Jovian derives from Jupiter.
The Outer/Jovian planets are as follows: * Jupiter * Saturn * Uranus * Neptune Pluto is not included anymore.
Mars is considered a terrestrial planet because it is rocky and mostly composed of silicate minerals and metals. Jovian planets, on the other hand, are gas giants like Jupiter and Saturn, which primarily consist of hydrogen and helium.
No. Pluto is significantly less dense than the terrestrial planets. A large portion of Pluto is made of ice, which is less dense than thr eock and metal that compose the terrestrial planets.
It seems there is no general consensus about the exact definition of "Jovian planets." Depending on the definition used, Neptune is, or is not, a "Jovian planet"; as explained on Wikipedia: "Giant planets are also sometimes called jovian planets, after Jupiter. They are also sometimes known as gas giants. However, many astronomers apply the latter term only to Jupiter and Saturn, classifying Uranus and Neptune, which have different compositions, as ice giants. ..."
Pluto is not considered a Jovian planet because it is much smaller and composed primarily of rock and ice, whereas Jovian planets are large gas giants composed mostly of hydrogen and helium. Additionally, Pluto's orbit is more elliptical and tilted compared to the Jovian planets, which follow more circular orbits in the outer solar system.
Pluto is the only "planet" that isn't a planet. Well I think that the IAU still have not answered the question WHAT MAKES A PLANET A PLANET? Is it a certain size or something? Comment : The IAU have defined a planet. The definition is mainly about size, but it's not simple: 1) The object must be big enough for gravity to have formed it into a (roughly) spherical shape. 2) The object must be by far the largest object in the neighbourhood of its orbit. Pluto qualifies on 1) but fails on 2). Also, Venus and Mercury are sometimes called "morning stars" or "evening stars", but they are planets.
Pluto is classified as a dwarf planet rather than a Jovian or terrestrial planet. It is located in the Kuiper Belt, a region of space beyond Neptune, and is much smaller and less massive than the traditional planets in our solar system.
