"Unprecedented Discovery: Two Planets Coexisting in Perfect Orbital Harmony"
While the International Astronomical Union's definition of a planet rules out two planets sharing the same orbit, it is possible for two Earth-like planets to coexist in a stable orbit around their star. The concept of co-orbiting planets challenges the traditional definition of a planet, but simulations and observations suggest that it is feasible. Various mechanisms, such as Lagrange points and orbit swapping, can allow for quasi-stable configurations that can last billions of years. Although no binary planet candidates have been discovered yet, with improved technology and more data, it is expected that examples of co-orbiting planets will be found in the future.
