All this new information represents a significant increase in our understanding of the outer Solar System.
Using data from the Dark Energy Survey conducted in 2013-2019 to study how the universe is expanding, astronomers spotted 461 trans-Neptunian objects in a previously unexplored region of the solar system .
Over 450 Previously Unknown Objects Have Been Discovered in Our Solar System
The outer reaches of the Solar System constitute a strange and mysterious place. Out past the orbit of Neptune, where it's cold and dark, a swarm of icy objects called the Kuiper Belt orbits the Sun, thought to be more or less unchanged since the Solar System was born.
Because it's so dark and far away, and the objects so small, it's hard for astronomers to discern what exactly is out there. This makes the results of a recent search quite marvelous.

Survey detects 461 Solar System objects not found before
A six year study to search for phenomena such as supernovae and galaxy clusters that could help scientists calculate how fast the Universe is expanding, has instead discovered 461 new objects in the outer Solar System.
Found as part of the Dark Energy Survey (DES), which as its name suggests is designed to help uncover the nature of dark energy, these objects are among a population of small bodies that orbit beyond Neptune called trans-Neptunian objects (TNOs).
Debris from early solar system collisions is missing because it got vaporized
The asteroid belt might as well be the solar system's junkyard. Asteroids, comets and other objects floating around in there are mostly trash from eons ago.
Gabriel and Allen-Sutter used an existing hydrodynamics code that simulates what rocks undergo when exposed to extreme conditions, such as the overkill gravity that occurs when they smack into each other, which has enough power to make those rocks behave more like a fluid.
Mystery Planet Nine In Our Solar System: Scientists Know Where To Look
The existence of "Planet Nine" has drawn divided attention from scientists. While many are convinced of another world beyond our solar system, others warn that it may as well be wishful thinking.
Now, scientists have charted a pathway to pinpoint the location of a potential ninth planet in our solar system beyond the former planet of Pluto .

There Should be More Material Left Over From Bombardment Eras. Maybe the Sun Blew it all Away?
Two researchers from Arizona State University's School of Earth and Space Exploration , former NewSpace Postdoctoral Fellow Travis Gabriel and doctoral student Harrison Allen-Sutter , conducted extensive computer simulations of the early solar system to track what happened to the debris when
Neptune at opposition: You need to see the Solar System's most elusive planet
Perhaps you're familiar with Neptune , the Roman god of the sea. Or maybe you know him by his Greek moniker, Poseidon. Despite the ancient mythos, the planet that bears the name as a result of its cerulean color — evoking the image of a great ocean world — was only discovered in 1846.
It is still a "star" in the sense that it is famous in our night skies, however — but not for the reason you might think. Neptune is not showy like Jupiter or Venus. Rather, it is the farthest known planet from the Sun, so its fame stems from its sheer elusiveness.
