Meteorite Database

Part of the Planetary Science Datasets collection on Hugging Face.

Catalogue of 1,180 known meteorites sourced from Wikidata, covering mass, classification, fall date, country of recovery, and geographic coordinates.

Dataset description

Meteorites are extraterrestrial rocks that survive passage through Earth's atmosphere and reach the surface. They are classified by mineralogy and petrology (e.g., chondrites, achondrites, iron meteorites) and recorded either as falls (witnessed descent) or finds (recovered without observation).

This dataset aggregates Wikidata entries for all entities of type Q60186 (meteorite), pulling structured properties including mass (P2067), fall/discovery date (P585/P575), country (P17), coordinates (P625), and mineralogical class (via P31 subclass hierarchy). It complements NASA and Meteoritical Society databases with Wikidata's multilingual, cross-linked knowledge graph.

Schema

Column	Type	Description
`wikidata_id`	string	Wikidata entity ID (e.g. Q1029)
`name`	string	Meteorite name
`fall_date`	string	Date of fall or recovery (YYYY-MM-DD)
`mass_g`	float	Mass in grams
`classification`	string	Mineralogical/petrological classification
`country`	string	Country of recovery
`latitude`	float	Recovery latitude (decimal degrees)
`longitude`	float	Recovery longitude (decimal degrees)

Quick stats

1,180 meteorites total
368 with recorded mass
415 with geographic coordinates
125 with classification
55 countries of recovery
Heaviest: Allende meteorite (2,000,000 g)

Usage

from datasets import load_dataset

ds = load_dataset("juliensimon/meteorite-database", split="train")
df = ds.to_pandas()

# Heaviest meteorites
print(df.nlargest(10, "mass_g")[["name", "mass_g", "country", "classification"]])

# Meteorites by country
print(df["country"].value_counts().head(10))

# Meteorites with coordinates (mappable)
mappable = df.dropna(subset=["latitude", "longitude"])
print(f"{len(mappable):,} meteorites with coordinates")

# Filter by classification
chondrites = df[df["classification"].str.contains("chondrite", case=False, na=False)]
print(f"{len(chondrites):,} chondrites")

Data source

Wikidata SPARQL endpoint. Meteorites identified via property P31 (instance of) = Q60186 (meteorite). Data is community-curated and cross-referenced with the Meteoritical Bulletin Database.

Update schedule

Quarterly (January, April, July, October). Run manually to capture interim additions.
