🌌 Minor Planet Center Asteroid Scraper

Extract comprehensive asteroid data from the Minor Planet Center's MPCORB.DAT database through Asterank's powerful API. Get detailed orbital parameters, physical characteristics, and observational data for over 600,000 asteroids with flexible filtering capabilities.

✨ Why Use Minor Planet Center Asteroid Scraper?

• 🚀 Fast & Efficient - Direct API access delivers asteroid data in seconds
• 📊 Rich Data - Complete orbital parameters, physical properties, and observational history
• 🔍 Powerful Filtering - MongoDB-style queries for precise asteroid selection
• 📈 Scalable - Retrieve from 1 to thousands of asteroids in a single request
• 🎯 Reliable - Data updated nightly from the official MPC database
• 📋 Clean Output - Structured JSON data ready for research and analysis

📥 Input Parameters

Note: The API supports complex MongoDB-style queries with operators like $lt, $gt, $ne, $in, etc.

📖 Usage Examples

Example 1: Get All Asteroids

Retrieve the first 100 asteroids without any filtering:

{
"query":{},
"limit":100
}

Example 2: Near-Earth Asteroids

Find asteroids with semi-major axis less than 1.5 AU:

{
"query":{
"a":{"$lt":1.5}
},
"limit":50
}

Example 3: Circular Orbits

Find asteroids with nearly circular orbits (low eccentricity) and low inclination:

{
"query":{
"e":{"$lt":0.1},
"i":{"$lt":4}
},
"limit":200
}

Example 4: Bright Asteroids

Find bright asteroids with low absolute magnitude:

{
"query":{
"H":{"$lt":15}
},
"limit":100
}

Example 5: Recently Observed

Find asteroids observed in 2023 or later:

{
"query":{
"last_obs":{"$regex":"202[3-9]"}
},
"limit":150
}

📤 Output Data

Each asteroid result includes comprehensive orbital and physical data:

}

Data is delivered in clean JSON format, ready to download as JSON, CSV, Excel, or integrate via API.

🔍 Query Operators

The API supports standard MongoDB query operators:

• Comparison: $lt (less than), $gt (greater than), $lte, $gte, $ne (not equal)
• Membership: $in (in array), $nin (not in array)
• Logical: $and, $or, $not
• String: $regex (regular expression), $exists

❓ FAQ

Q: How many asteroids are in the database?
A: Over 600,000 asteroids with data updated nightly from the MPC.

Q: What do the orbital parameters mean?
A: a = semi-major axis (AU), e = eccentricity, i = inclination (degrees), H = absolute magnitude.

Q: Can I filter by discovery date?
A: The API focuses on orbital parameters. Use the last_obs field for recent observations.

Q: Are there rate limits?
A: Yes, using Apify Proxy is recommended to avoid rate limiting from the Asterank API.

Q: Can I get data for specific asteroids?
A: Yes, use the des field with exact designation matching in your query.
