About Planet
A planet is a celestial body, apparently bigger than poor little Pluto, orbiting a star. They typically have semi-solid metalic core, and the rest of the planet can be either gaseous like Jupiter and Saturn, or more dense and solid like Earth and Mars.
About Planet X
Planet X is a theoretical planet thought to be beyond the orbits of Neptune and Uranus. Astronomers thought this planet could exist because of eccentricities in the orbits of the two ice giants. In the 1990s it was discovered the eccentricities were due to an over estimation of Neptune's mass. It is widely agreed that Planet X does not exist in our solar system.
About Solar system
The Solar system refers to the 8 planets, hundreds of moons, and billions of asteroids and comets other celestial bodies orbiting the star Sol. Sol is the name of our sun.
