New minor planets beyond Neptune


Using data from the Dark Energy Survey (DES), researchers have found more than 300 trans-Neptunian objects (TNOs), minor planets located in the far reaches of the solar system, including more than 100 new discoveries. Published in The Astrophysical Journal Supplement Series, the study also describes a new approach for finding similar types of objects and could aid future searches for the hypothetical Planet Nine and other undiscovered planets. The work was led by graduate student Pedro Bernardinelli and professors Gary Bernstein and Masao Sako

How This is news escapes me.

It's not "mapped" and we aren't sure what it contains.

Also, despite his, "duh", comment, Tuco's Gas is incorrect about it simply being the Kuiper Belt.

Many of these trams-Neptunian objects belong to something called the scattered disk.

Objects in the scattered disk are of major interest to astronomers as it is here, not the Kuiper Belt, that periodic comets originate. 

In theory TNOs also include Oort cloud objects but it is highly unlikely that this survey would has seen any of them.

Would have been fun for Voyager who traveled around 141 astronomical units had passed near some of these celestial body ! Space is so big between these... Don't know if it would have been able to take and relay data in the case of an encounter.
