there are no confirmed cases of double planets orbiting each other in our solar system or in any known star system. In our solar system, planets generally orbit around a star, with the largest planet in a system typically having other smaller objects, such as moons, orbiting around it.
However, it's important to note that the term "double planet" is not clearly defined, and there have been debates about what constitutes a double planet. One example often mentioned is the dwarf planet Pluto and its largest moon, Charon. They are often referred to as a binary system or binary dwarf planets because their center of mass is located outside of Pluto. Some argue that Pluto-Charon should be considered a double planet system rather than a planet-moon system. However, this is not a widely accepted classification.
It's worth mentioning that astronomers are constantly discovering new celestial objects and systems, so our understanding of the universe is continually expanding. It's possible that future observations may reveal double planets or similar systems beyond what is currently known.
