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.
The International Astronomical Union (IAU) classifies objects in our solar system into several categories based on their characteristics. These include planets, dwarf planets, moons, asteroids, comets, and meteoroids. The classification primarily considers factors like size, shape, and orbital dynamics, as well as the object's ability to clear its orbit of other debris. This system helps in organizing and understanding the diverse range of celestial bodies within 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.
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.

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.
Three examples of man-made space objects include the Hubble Space Telescope, which has provided invaluable astronomical observations since its launch in 1990; the International Space Station (ISS), a collaborative effort for scientific research and international cooperation in space; and the Voyager 1 spacecraft, launched in 1977, which has traveled beyond our solar system and continues to send back data. These objects demonstrate humanity's ability to explore and utilize space.
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.
