Japanese Astronomers Discover Possible Earth-like Planet

Japanese astronomers have announced the possible existence of a planet similar to Earth. Scientists observed asteroids and found that a large number of small objects behave as if there is a small planet among them, indicated by an orbit with a specific inclination. The object is located in the Kuiper Belt and is estimated to have a mass 1.5-3 times that of Earth, an orbit inclination of approximately 30 degrees, and an orbit distance of 250-500 astronomical units from the Sun.
