Astronomers from the University of Pennsylvania have discovered 139 new minor planets orbiting the sun. These minor planets also called trans-Neptunian objects (TNOs) hide beyond Neptune’s orbit in the Kuiper Belt. They are neither official planets nor comets.
Some famous trans-Neptunian objects that you might know are ex-planet Pluto, Eris, Haumea, and MakeMake.
The findings were published in the Astrophysical Journal. These findings are significant because it could also lead astronomers to a obscure Planet Nine, a theoretical large planet that some astronomers believe orbits the sun way in the depths of the solar system.
So far, astronomers have discovered more than 3,000 of these trans-Neptunian objects—a small part of what’s assumed to be out there.
