Did the scientists behind the Planet Nine hypothesis make an embarrassing mistake?
For years now, a team of astronomers have supported a controversial theory that a ninth planet is circling the Sun at an orbit beyond Neptune.
Since 2016, Mike Brown and Konstantin Batygin from the California Institute of Technology have argued that the erratic behavior of unusually clustered TNOs orbiting the Sun at extremely tilted and elongated orbits could be explained by the gravitational forces of a hypothetical Planet Nine, a celestial body about ten times the mass of Earth.
Compounding the argument, TNOs are still shrouded in mystery. By nature, TNOs are extremely difficult to observe since they are so far away. The best way to spot them is once they zip past the inner Solar System during their unusual orbits, but even then they are hard to make out in front of the relatively bright Milky Way, according toWhat we do know is that there are plenty of them in our star system.
