Does Earth have a 'twin' planet?

A group of Japanese astrophysicists has discovered possible evidence of the existence of a planet, slightly larger than Earth, located in the Kuiper belt. This is a significant finding that could contribute to our understanding of the solar system and planets beyond our own.

The belt they refer to is known as the Kuiper belt. It consists of a collection of objects that orbit the Sun in a region beyond Neptune, about 30 AU away (one astronomical unit is equivalent to the average distance between the Earth and the Sun).

strange behaviors

A group of researchers has found intriguing evidence in the Kuiper Belt. It seems that some objects, such as asteroids, space rocks and comets, show peculiar behavior that suggests the existence of a small planet in their midst. This discovery raises new questions about the composition and dynamics of this region of the solar system. The existence of a hypothetical ninth planet has been proposed whose orbit would be located at a distance of approximately 250 to 500 AU (astronomical units) from the Sun. This means that it would be much closer to the Sun than the outer edge of the solar system.

Scientists have observed that some of the trans-Neptunian objects (TNOs) have unusual orbits, indicating that they are being affected by the gravitational pull of an object larger than those common TNOs. This evidence demonstrates the presence and effect of another celestial body nearby. It is interesting to note that many of these objects had an orbit with a considerable inclination.

Computer simulations suggest a twin planet of Earth

Through computer simulations, it has been determined that the most likely explanation for the observations made is the presence of a planet in the Kuiper belt. This planet would have a mass between 1.5 and 3 times that of Earth, as well as an inclination in its orbit of approximately 30 degrees.

Recently, the results of this study were released in The Astronomical Journal. This scientific publication is recognized for its rigor and prestige in the field of astronomy. The findings presented in this study are important to the scientific community and can contribute to the advancement of knowledge in this area.
