# Webb telescope finds 27 new objects beyond Neptune in deepest survey yet

The James Webb Space Telescope detected 27 previously unknown Trans-Neptunian Objects in a small patch of sky, some as small as six miles across, in the most sensitive study of these icy worlds to date.

Astronomers using NASA's James Webb Space Telescope have identified 27 new Trans-Neptunian Objects - small icy bodies orbiting beyond Neptune - in a small patch of sky, some only about six miles wide, in the most sensitive study of such worlds to date.[^1]

The objects belong to two major families: one on calm, nearly circular orbits and one on tilted, stretched orbits. Both families share almost the same size pattern down to the smallest objects detected, suggesting planetesimal formation may work the same way under many different conditions.[^2]

The read here is that the size pattern matching across two distinct orbital populations is the notable result - it points to a common formation mechanism that operated regardless of where in the early Solar System these bodies formed. The survey's sensitivity, reaching objects as small as six miles across, opens a window on the smallest members of the outer Solar System's population.
