A Brief Introduction to Despina: Neptune's Innermost Small Moon
Neptune, the eighth planet of our solar system, is known for its blue hue and turbulent weather patterns. It is the fourth-largest planet by diameter and the third-most massive planet in our solar system. Although it has 14 moons, one of its most intriguing moons is Despina. This small innermost moon orbits Neptune at a distance of approximately 52,526 km from the planet's center and was discovered on July 2nd, 1989 by NASA's Voyager 2 spacecraft.
The Discovery of Despina
Despina was first observed by the Voyager 2 spacecraft during its flyby mission to Neptune in August 1989. The spacecraft captured several images of this small moon during its approach to Neptune, revealing a tiny body with an irregular shape measuring roughly about 150 x 126 x110 km across. The discovery came as a surprise as it was not detected by Earth-based telescopes before then.
Naming Despina
The name "Despina" comes from Greek mythology and means "mistress" or "lady." In Greek mythology, Despoina (with an o) was one of two daughters born to Demeter (goddess of agriculture) and Poseidon (Neptune). However, the name changed slightly due to naming conventions in astronomy where all planetary satellites are named after characters from Greek or Roman mythology associated with either Neptune or Poseidon.
Physical Characteristics
Despina has an irregular elongated shape that gives it a potato-like appearance with dimensions measuring roughly about150 x126x110 km across. Its surface features appear heavily cratered but lack any noticeable large impact craters like other moons within our solar system such as our own Moon or Jupiter's Europa.
Despite being so close to Neptune’s gravity field which exerts tidal forces on this moon, its surface is not significantly altered. This suggests that Despina has a relatively rigid interior and may contain a small amount of water ice.
Despina's Orbit
Despina orbits Neptune in an almost circular orbit with a radius of approximately 52,526 km or about 0.353 times the radius of Neptune itself. It completes one full orbit around Neptune every eight hours and twenty-nine minutes, making it one of the fastest-orbiting moons in the solar system.
The Discovery Process and Early Research on Despina
The discovery of Despina was a significant milestone in the exploration of our solar system. It marked one of the first times that a moon had been discovered by a spacecraft, rather than through ground-based observations. In this section, we will explore the discovery process and early research conducted on Despina.
Voyager 2's Flyby Mission
In August 1989, NASA's Voyager 2 spacecraft flew by Neptune as part of its grand tour mission to study the outer planets of our solar system. During its approach to Neptune, Voyager 2 captured several images of the planet's moons, including Despina.

Despina is a small, irregularly shaped moon that orbits within Neptune's gravitational field. Despite its small size, there are several theories and hypotheses regarding how this mysterious little moon came into existence. In this section, we will explore some of the leading ideas regarding Despina's origin story.
Captured Moon Theory
One of the most widely accepted theories regarding Despina's origin is that it was captured by Neptune's gravity. According to this theory, Despina was once a free-floating object in space before being pulled into orbit around Neptune.
Although captured moons are not uncommon in our solar system such as Saturn’s moons Phoebe or Iapetus; researchers believe that if Despina was indeed captured by Neptune, it would have undergone significant changes to its shape due to tidal forces exerted upon it.
Accretion Theory
Another theory suggests that Despinamay have formed from leftover debris from the formation of Neptune and its moon system. According to this hypothesis, particles in orbit around the planet collided with each other over time until they eventually coalesced into a single body - which later became known as Despina.
However, studies suggest that if accretion were responsible for formingDespinathen why does it have an elongated shape remains puzzling since accretion should result in more spherical shapes similar to other moons in our solar system like Mimas or Dione orbiting Saturn .
Collisional Processes Hypothesis
A third theory posits thatDespinamight have formed through collisional processes involving smaller bodies already present withinNeptune’s gravity field during its early formation period . These collisions may have resulted in the agglomeration of these smaller bodies into one larger one - again resulting in what we know today asDespinawith its elongated shape but why collisions would result in elongated shapes remains a mystery.
Tidal Disruption Theory
A less accepted theory suggests thatDespinamay have been formed from the tidal disruption of another moon orbiting Neptune. According to this hypothesis, a larger moon was pulled apart by the planet's powerful gravitational forces until it eventually coalesced into Despina.
While this theory has some merit, there is currently no direct evidence to support it, and many researchers believe that other theories are more likely.
