How did scientists discover the dwarf planets in our solar system?

Answer 1

Dwarf planets were detected by the same way as we detect planets and satellites.Dwarf planets reflect sun light.So we can see them in large telescopes..

Most dwarf planets re smaller and they are far away than the the Planets and they receive very less light from Sun..So systematic observation over long periods only they were detected. picture credit Wikipedia,

Through a combination of telescope observations and data analysis, scientists have found dwarf planets in our solar system. These objects were first identified as possible dwarf planets because of their size, location, and other characteristics, like not having other debris in their orbits. The process of finding dwarf planets in our solar system involved searching the sky for celestial bodies that were beyond Neptune's orbit and evaluating their properties to see if they fit the criteria for being classified as dwarf planets.
