Neptune, one of our solar system's outermost planets, has a little-known moon called S/2004 N 1. This small moon was first discovered in 2013 by a team of astronomers from the SETI Institute. S/2004 N 1 is the fourteenth moon to be discovered orbiting around Neptune and is the smallest of all the planet's moons. It is about 20 kilometers in diameter and is irregularly shaped, making it a unique object in the Neptunian system. Even though it is small, S/2004 N 1 is still an essential object to study, as it provides insights into the formation and evolution of the Neptunian moon system. This article will take a closer look at S/2004 N 1, its discovery, characteristics, and what we know about it so far.
The Exploration of Neptune's Moons
S/2004 N 1: The Discovery
S/2004 N 1 is the smallest moon of Neptune, and it was discovered on July 1st, 2013, by Mark R. Showalter using the Hubble Space Telescope. It took almost ten years to be detected because of its small size and dimness. This tiny moon is only about twenty kilometers in diameter and orbits Neptune every twenty-four hours.
Characteristics of S/2004 N 1
Despite its small size, scientists have been able to learn a lot about this mysterious little moon. S/2004 N 1 has a highly eccentric orbit that takes it from around seventeen thousand kilometers away from Neptune to just over forty-five thousand kilometers away from the planet. This means that its distance from Neptune varies significantly during each orbit.
Additionally, this small moon appears to be part of a ring system around Neptune which indicates that it may have formed when one or more larger moons were shattered in an impact with another object.
The Importance of Studying Small Moons
The discovery and exploration of smaller moons like S/2004 N 1 are essential for understanding how planets and their moons form and evolve over time. These tiny moons often hold clues about the early formation processes within a planetary system as they are typically less altered by geological activity than larger moons or planets.
Furthermore, studying these smaller celestial bodies can also tell us more about our solar system's history as well as other planetary systems throughout the universe.
