Scientists Think an Earth-Like Planet May Be Hiding in Our Solar System

Scientists propose an alternative to the hypothetical Planet Nine, suggesting a smaller, Earth-like planet closer to our solar system. This planet, no more than three times the mass of Earth and within 500 astronomical units from the Sun, could explain the peculiar clustering behaviors of trans-Neptunian objects (TNOs). The researchers believe this planet’s gravity could be influencing the orbits of these distant objects, offering a new perspective on the dynamics of our solar system.
