Neptune, the outermost planet in our solar system, plays a crucial role in understanding the evolution of celestial bodies. Among its moons, Nereid, discovered in 1949, has remained a subject of intrigue due to its eccentric orbit. Recent research led by graduate student Matthew Belyakov at Caltech, in collaboration with Professors Konstantin Batygin and Mike Brown, has provided new insights into Nereid's origins. Utilizing the James Webb Space Telescope (JWST), the team observed Nereid's spectrum, revealing similarities to the moons of Uranus rather than to Kuiper Belt Objects (KBOs). This suggests that Nereid may not have been captured by Neptune but instead formed in situ. The simulations developed by Belyakov indicate that the capture of Triton, Neptune's largest moon, could have disrupted the orbits of existing moons, leading to Nereid's current trajectory. Belyakov emphasizes the importance of understanding Nereid's formation to unravel the history of Neptune and the early solar system. The research, published on May 20 in Science Advances, calls for further observational studies of Nereid, which remains faint and distant, yet holds key insights into the dynamics of Neptune's moon system.
