The International Astronomical Union (IAU) is the organization responsible for officially classifying celestial bodies, including planets. They determine the criteria that define what constitutes a planet and ultimately decide on the status of objects in our solar system.
"Pluto was reclassified from a planet to a dwarf planet in 2006 by the International Astronomical Union due to its size and its orbit overlapping with Neptune's. This decision was made to more accurately classify celestial objects in our solar system."
The system of latitude/longitude is an imaginary matrix that's pinned to the Earth's surface, and was created in order to describe locations on the Earth's surface. The system used to describe the locations of astronomical objects in the sky is similar but separate, and is pinned to the imaginary dome of the sky. You may have noticed that the position of astronomical objects over the Earth's surface is constantly changing ... it only takes a few minutes to notice the change ... and that the positions of the planets change even among the rest of the astronomical objects.
Pluto is the smallest planet in our solar system, but it was reclassified as a dwarf planet by the International Astronomical Union in 2006.
In 2006, the International Astronomical Union redefined the criteria for what constitutes a planet and reclassified Pluto as a dwarf planet. This decision was influenced by new discoveries of similar-sized objects in the outer solar system and refined definitions of what characteristics a planet should possess.
Scientists classify small objects in the solar system by size, shape, and composition

Distant objects in space such as galaxies, quasars, and nebulae are commonly referred to as astronomical objects. These objects are typically located far beyond our solar system and can be observed through telescopes and other astronomical instruments.

Astronomical Unit- The distance between objects in the solar system!

A "distance" must be specified between two objects. There is no "distance of the Solar System" by itself.
Our solar system is called the "Solar System" which consists of the Sun and all the astronomical objects orbiting around it, including planets, moons, asteroids, comets, and dust.
Scientists classify planets based on their characteristics such as size, composition, atmosphere, and orbit around a star. Planets are typically categorized as terrestrial (rocky) or gas giants, with further distinctions based on their location within a solar system and other attributes. The International Astronomical Union provides guidelines for classifying celestial bodies in our solar system and beyond.
Longitude and Latitude are used to refer to positions ON EARTH and are not used to locate the position of astronomical objects. In astronomy, a celestial coordinate system is a system for specifying positions of celestial objects. Orion's position is:- Right Ascension 5h , Declination +5°
On August 24, 2006, Pluto was reclassified by the International Astronomical Union (IAU) as a "dwarf planet", a classification shared by the asteroid Ceres and three trans-Neptunian Kuiper Belt objects : Eris, Haumea, and Makemake. (Kuiper Belt object Sedna is a current candidate as well.)
