Philophrosyne has an approximate diameter of 2 kilometers.
Understanding Philophrosyne's Dimensions
Philophrosyne is one of Jupiter's many natural satellites, a small moon whose physical characteristics and orbital parameters provide insights into the Jovian system. Its size is a key feature, indicating its classification among the smaller moons orbiting the gas giant.
Key Characteristics of Philophrosyne
This moon is part of Jupiter's extensive collection of irregular satellites, typically characterized by their small size, distant orbits, and often retrograde motion. Philophrosyne's relatively small diameter places it among these numerous minor celestial bodies.
Here's a breakdown of Philophrosyne's observed properties, including its diameter, as well as its orbital data around Jupiter:
| Characteristic | Value |
|---|---|
| Diameter | Approximately 2 kilometers |
| Orbital Body | Jupiter |
| Average Orbital Distance | 22,721,000 km |
| Orbital Period | 699.676 days |
| Orbital Inclination | 142° to the ecliptic (142° to Jupiter's equator) |
| Orbital Direction | Retrograde |
| Orbital Eccentricity | 0.0932 |
Significance of Small Moons
Moons like Philophrosyne, despite their modest size, are crucial for astronomers studying the formation and evolution of planetary systems. Their orbital characteristics, such as retrograde motion and high inclination, often suggest they are captured asteroids rather than having formed in situ around Jupiter. The study of these small, irregular moons helps scientists reconstruct the early history of the solar system and understand the dynamics of gravitational interactions within giant planet systems.
