Solar System Moons

Part of the Planetary Science Datasets collection on Hugging Face.

Every known natural satellite of planets and dwarf planets in the Solar System — currently 440 moons spanning discovery years 1610 to 2025.

Dataset description

This dataset catalogs all recognized natural satellites orbiting the major planets (Earth through Neptune) and the dwarf planet Pluto, as maintained by NASA's Jet Propulsion Laboratory (JPL) Solar System Dynamics group. Each record combines discovery circumstances, mean orbital elements, and — where available — physical parameters (radius, density, gravitational parameter).

The dataset merges three authoritative JPL tables:

Discovery circumstances — name, parent body, year, discoverer
Mean orbital elements — semi-major axis, eccentricity, inclination, period
Physical parameters — mean radius, GM, density (for 46 major moons)

Quick stats

Saturn: 285 moons
Jupiter: 101 moons
Uranus: 30 moons
Neptune: 16 moons
Pluto: 5 moons
Mars: 2 moons
Earth: 1 moons
439 moons with orbital elements
46 moons with measured radius
297 retrograde moons (inclination > 90°)
Largest moon: Ganymede (Jupiter, radius 2,631.2 km)

`long_ascending_node_deg`	float64	Longitude of ascending node (degrees)
`epoch`	string	Epoch of orbital elements (TDB)
`mean_radius_km`	float64	Mean radius (km), major moons only
`diameter_km`	float64	Mean diameter (km), derived from radius
`gm_km3s2`	float64	Gravitational parameter GM (km³/s²)
`mean_density_gcm3`	float64	Mean bulk density (g/cm³)
`is_retrograde`	bool	True if inclination > 90°
`jpl_code`	string	JPL numeric satellite identifier

Usage

from datasets import load_dataset

ds = load_dataset("juliensimon/solar-system-moons", split="train")
df = ds.to_pandas()

# Moons per planet
print(df["parent_body"].value_counts())

# Galilean moons of Jupiter
galilean = df[df["group"] == "Galilean"]

# Retrograde irregular satellites
retro = df[df["is_retrograde"] == True].sort_values("orbital_period_days")

# Largest moons by radius
biggest = df.dropna(subset=["mean_radius_km"]).nlargest(10, "mean_radius_km")

# Recent discoveries (2020+)
recent = df[df["discovery_year"] >= 2020]
