# ESA Near Earth Objects MCP

> ESA Near Earth Objects provides mission-critical asteroid data from the European Space Agency's NEOCC. It lets you query object orbital elements, monitor impact risk lists (Palermo/Torino Scale), and track upcoming close approaches for any known near-Earth object. Access the most authoritative planetary defense intelligence directly through your AI client.

## Description

This MCP connects your agent to the European Space Agency Near-Earth Object Coordination Centre, giving you direct access to some of the world's most reliable asteroid tracking data. You don't need to navigate complex web portals or wrestle with differing academic sources; you just ask for the information, and it appears. You can pull up a full object profile—including its orbital path, physical size estimates, and current risk rating—for any designation. This capability is essential for everything from scientific research planning to rapid incident response.

If your workflow requires synthesizing multiple data points—say, comparing an object's historical flyby record against its current calculated trajectory—this MCP handles the cross-referencing. You route all this mission-critical intelligence through Vinkius, letting any compatible AI client pull together a single, coherent report based purely on ESA standards. It’s planetary defense data, ready for your workflow.

## Prompt Examples

**Prompt:** 
```
Show me all asteroids approaching Earth in the next few months.
```

**Response:** 
```
I've retrieved the ESA NEOCC upcoming close approaches list. There are currently 87 objects tracked. The closest approach today is asteroid 2022UU8, passing at 3.34 million km (8.7 lunar distances) with a diameter of approximately 9 meters. Would you like me to check the risk assessment for any of these objects?
```

**Prompt:** 
```
Are there any asteroids currently on the ESA risk list?
```

**Response:** 
```
I've fetched the ESA risk list. There are currently several objects with non-zero cumulative impact probability. The highest-rated object has a Palermo Scale value of -2.3 and Torino Scale 0. None currently warrant public concern — all are within normal background risk levels. Would you like the orbital details for any specific object?
```

**Prompt:** 
```
Get me the orbital elements and physical properties of asteroid 2024YR4.
```

**Response:** 
```
Querying the NEOCC database for 2024YR4... The orbital elements show a semi-major axis of 1.47 AU, eccentricity 0.42, inclination 3.8°. The physical properties indicate an estimated diameter of 40-90 meters with absolute magnitude H=24.7. This object was flagged for follow-up observations. Would you like to see its computed ephemerides for telescope planning?
```

## Capabilities

### Assess overall impact risk
Pull the official list of potentially hazardous objects and their associated Torino and Palermo Scale ratings.

### Determine object trajectory details
Retrieve precise orbital parameters, including semi-major axis and inclination, for detailed celestial mechanics calculations.

### Track future encounters
Get projected dates and distances for asteroids approaching or passing near Earth in the coming months.

### Compile physical profiles
Access estimated object dimensions, albedo, and spectral type from dedicated ESA databases.

### Analyze historical flybys
Review recorded data points detailing close approaches that have already occurred.

## Use Cases

### Assessing a potential collision risk
A defense team needs to know if two asteroids might cross paths. They query `get_object_orbital_elements` for both, then use `get_upcoming_close_approaches` to find the precise time and minimum separation distance.

### Preparing an academic paper on NEOs
A researcher needs a background report. They start by calling `get_risk_list` for context, then use `get_object_physical_properties` to gather size and albedo data for the top-ranked objects.

### Validating a mission trajectory
A space agency needs to confirm an object's path. They run `get_object_ephemerides` over a 6-month window and compare it against historical data from `get_recent_close_approaches`.

### Quickly checking for newly flagged hazards
A monitoring specialist needs to know if any recently discovered objects are high priority. They check the `get_special_risk_list` and cross-reference it with the general impact findings from `get_impact_table`.

## How It Works

The bottom line is that you get real-time access to the ESA's planetary defense database without ever leaving your AI agent environment.

1. Subscribe to this MCP on Vinkius. No API key is required because the ESA NEOCC data is a public service.
2. Direct your query to your AI client (Claude, Cursor, etc.) asking for specific object details or risk assessments.
3. Receive structured, mission-critical data containing orbital elements, impact probabilities, and approach distances directly in your workflow.

## Frequently Asked Questions

**How do I check if a specific asteroid is currently high risk using `get_risk_list`?**
You simply query the list and look for the Palermo Scale or Torino Scale ratings. The data provides immediate, official assessments of cumulative impact probability.

**What is the difference between `get_upcoming_close_approaches` and `get_object_close_approaches`?**
`get_upcoming_close_approaches` forecasts future events for a given period, while `get_object_close_approaches` retrieves specific data points for an object's encounters, useful for historical or focused analysis.

**Can I get the orbital elements for many objects at once? Use `get_all_nea_list`.**
You can retrieve all designations using `get_all_nea_list`, but you must then query each one individually with `get_object_orbital_elements` to pull useful, actionable data.

**How do I check the current status of this MCP? Use `check_esa_neocc_status`.**
Calling `check_esa_neocc_status` confirms that the connection is live and provides the service URL, ensuring your queries are sent to a working data source.

**When I use `get_object_ephemerides`, what format do the coordinates arrive in?**
The data returns a time series of Right Ascension, Declination, distance, and visual magnitude at specific timesteps. You receive multiple points for one object, allowing you to plot its position over an observation window.

**Do I need special handling if the orbital data from `get_object_orbital_elements` seems incomplete?**
The ESA NEOCC provides these elements based on available tracking arcs. If the data is sparse, it indicates insufficient historical observation to compute a full, stable trajectory.

**What's the functional difference between results from `get_risk_list` and `get_special_risk_list`?**
`get_risk_list` tracks objects with non-zero cumulative impact probability. Conversely, `get_special_risk_list` flags objects that are of heightened scientific importance regardless of their immediate risk score.

**If I run `get_all_nea_list`, how should I best process the resulting catalog?**
Since this list contains thousands of designations, you shouldn't attempt to query every object. Instead, use the returned designation IDs in subsequent tools like `get_object_physical_properties` for targeted analysis.

**Do I need an API key to use this server?**
No. The ESA NEOCC API is completely public and requires no authentication. Simply subscribe to this server and enter any placeholder value in the API key field to start querying asteroid data immediately.

**How often is the asteroid data updated?**
The ESA NEOCC updates its close approach data, risk lists, and impact monitoring tables multiple times per day. Orbital elements and physical properties are updated whenever new observational data becomes available from ground-based telescopes worldwide.

**Can I query data for a specific asteroid like Apophis?**
Yes! Use the object-specific tools with the asteroid's designation. For example, query orbital elements for '99942' (Apophis), or get close approaches for '2024YR4'. The designation should match the official IAU format used in the NEOCC database.
