Mysterious Planet X May Really Lurk Undiscovered in Our Solar System
“Planet X” might actually exist — and so might “Planet Y.”
At least two planets larger than Earth likely lurk in the dark depths of space far beyond Pluto, just waiting to be discovered, a new analysis of the orbits of “extreme trans-Neptunian objects” (ETNOs) suggests.
Researchers studied 13 ETNOs — frigid bodies such as the dwarf planet Sedna that cruise around the sun at great distances in elliptical paths. [Meet Our Solar System's Dwarf Planets]
Theory predicts a certain set of details for ETNO orbits, study team members said. For example, they should have a semi-major axis, or average distance from the sun, of about 150 astronomical units (AU). (1 AU is the distance from Earth to the sun — roughly 93 million miles, or 150 million kilometers.) These orbits should also have an inclination, relative to the plane
of the solar system, of almost 0 degrees, among other characteristics.
But the actual orbits of the 13 ETNOs are quite different, with semi-major axes ranging from 150 to 525 AU and average inclinations of about 20 degrees.
“This excess of objects with unexpected orbital parameters makes us believe that some invisible forces are altering the distribution of the orbital elements of the ETNOs, and we consider that the most probable explanation is that other unknown planets exist beyond Neptune and Pluto,” lead author Carlos de la Fuente Marcos, of the Complutense University of Madrid, said in a statement.
“The exact number is uncertain, given that the data that we have is limited, but our calculations suggest that there are at least two planets, and probably more, within the confines of our solar system,” he added.
The potential undiscovered worlds would be more massive than Earth, researchers said, and would lie about 200 AU or more from the sun — so far away that they’d be very difficult, if not impossible, to spot with current instruments.
