December 10, 2025, marks a monumental event as Neptune turns prograde, a rare shift in its orbit that brings a turning point in the outer solar system. Prograde motion occurs when a planet’s movement aligns with the solar system's natural rotation, and this shift in Neptune’s path offers a new perspective on the dynamics of our planetary neighbors. For stargazers and astronomy enthusiasts, this is a unique opportunity to observe a planetary change that happens only once in a while. | Holiday Mag
