🌌 ESA Gaia DR3 Star Catalog Scraper

🚀 Pull real stellar measurements from the ESA Gaia DR3 archive in one run. Query by ADQL or a simple cone search and get back source IDs, sky positions, parallax, proper motion, photometry, radial velocity, and effective temperature for every star.

The ESA Gaia mission has measured the positions, distances, and motions of nearly two billion stars. The Gaia Data Release 3 (DR3) catalog is the richest map of the Milky Way ever assembled. This Actor talks to the official Gaia Archive TAP service and turns that catalog into clean, structured records you can drop straight into a notebook, a database, or a dashboard.

You can run an exact ADQL query against the gaiadr3.gaia_source table, or skip the query language entirely and search a circular patch of sky by right ascension, declination, and radius. Either way you get the same well-typed records back.

🎯 Target Audience	💡 Primary Use Cases
Astronomers and astrophysics researchers	Building target lists for observing runs
Data scientists and ML practitioners	Training and testing stellar classification models
Educators and students	Teaching astrometry, parallax, and photometry
Science communicators and hobbyists	Mapping local stellar neighborhoods

📋 What the Gaia DR3 Star Catalog Scraper does

This Actor queries the ESA Gaia DR3 archive and returns one record per stellar source. For each source it collects the unique Gaia source identifier, right ascension and declination, trigonometric parallax, proper motion in RA and Dec, mean magnitudes in the G, BP, and RP photometric bands, radial velocity, and the GSP-Phot effective temperature. You control the selection with either a full ADQL query or a cone search.

📊 Data fields

Each record includes: dec, parallax, photBpMeanMag, photGMeanMag, photRpMeanMag, pmdec, pmra, ra, radialVelocity, results, scrapedAt, sourceId, teff. These field names come straight from the actor's dataset schema, so what you see here is what lands in your dataset.

🚀 How to use

1. Sign up for a free Apify account using this link.
2. Open the Gaia DR3 Star Catalog Scraper.
3. Either enter a cone search (RA, Dec, radius) or paste a full ADQL query.
4. Set how many records you want and start the run.
5. Collect your structured stellar records when the run finishes.
