New Moon Discovered Orbiting Uranus by James Webb Space Telescope
Table of Contents
Washington, D.C. – August 20, 2025 – In a groundbreaking discovery, NASA announced today that the James Webb Space Telescope has identified a previously unkown moon orbiting the planet Uranus. The finding, revealed on Tuesday, significantly expands our understanding of the Uranian system and highlights the telescope’s unparalleled capabilities.
A Tiny Moon Revealed
The newly discovered moon is estimated to measure approximately 10 kilometers in diameter. Scientists calculated its volume at 523.6 cubic kilometers, equivalent to 523.6 trillion liters of water. Remarkably, this volume is double that of Lake Toba, a massive volcanic lake located in North Sumatra, Indonesia, which holds roughly 240 cubic kilometers of water.
The moon’s existence was confirmed through infrared imaging captured by the Webb telescope during observations conducted in Febuary. Its diminutive size and faint reflectivity have allowed it to evade detection for decades, even eluding the Voyager 2 spacecraft during its flyby of Uranus approximately 40 years ago.
Did You Know? Uranus already boasts a collection of 28 known moons, all named after characters from the works of William Shakespeare and Alexander Pope.
Expanding the Uranian Family
With this latest addition, Uranus now has a total of 29 confirmed moons. The new moon has not yet received an official name. The discovery suggests the possibility of even more undiscovered satellites orbiting the ice giant.
“There’s a possibility that there are more out there,we just need to keep looking,” stated Matthew Tiscareno,a planetary scientist at the SETI Institute involved in the research.This sentiment underscores the ongoing exploration and potential for further discoveries within our solar system.

The discovery of this small moon provides valuable insights into the formation and evolution of the Uranian system. Understanding the composition and orbits of these moons can help scientists piece together the history of the planet and its surrounding habitat. NASA’s James Webb Space Telescope continues to revolutionize our understanding of the cosmos.
Pro Tip: The James Webb Space Telescope utilizes infrared technology, allowing it to penetrate dust clouds and observe objects that are invisible to conventional optical telescopes.
What implications might this discovery have for future missions to Uranus? And how will continued observations refine our understanding of the planet’s complex moon system?
Uranus: A Unique Ice Giant
Uranus is classified as an ice giant, distinguished by its composition of icy materials like water, methane, and ammonia. It’s unique among the planets in our solar system due to its extreme axial tilt,causing it to orbit the Sun on its side. This tilt results in highly unusual seasons and weather patterns. Further research into Uranus and its moons is crucial for understanding the diversity of planetary systems beyond our own.The planet’s atmosphere, magnetic field, and ring system continue to be areas of active investigation.
