## What's an Apify Actor?

An Actor is a serverless cloud program that runs on the Apify platform. It has two run modes.
In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours,
and optionally produces a well-defined JSON output, datasets with results, or files in key-value store.
In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server.

Apify vocabulary and the platform model are defined once, in the agent quickstart at https://apify.com/agents.md.

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For examples already wired to this Actor's own input schema, see the [API](#api) section below.

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).

# README

## Exoplanet Data: NASA Confirmed Planets, Size, Orbit & Distance

Query the NASA Exoplanet Archive for confirmed planets. Filter by name, discovery method and discovery year. Returns planet, host star, discovery year and method, orbital period, radius and mass (Earth units), star distance and archive link. Free public data, no API key.

### What does Exoplanet Data do?

Confirmed exoplanets from the NASA Exoplanet Archive: discovery year and method, radius, mass, orbit and distance.

### What can you use it for?

- Build astronomy dashboards and educational content.
- Analyse discovery trends by method and year.
- Find nearby or Earth-sized planets.
- Enrich science datasets.

### Why use this Actor?

- **Fast and cheap:** lightweight HTTP-based Actor with no browser, so runs finish in seconds and cost very little.
- **No API keys or accounts needed** for the data source (see notes below).
- **Clean, structured JSON** that you can export as CSV, Excel, JSON or XML, or pull through the Apify API and integrations.
- **Scheduling, webhooks and integrations:** run it daily and send results to Google Sheets, Slack, Zapier, Make, n8n or your own API.

### Input

Configure the run in the **Input** tab (all fields have sensible defaults).

| Field | Type | Required | Default | Description |
|---|---|---|---|---|
| `query` | string | no | - | Text in the planet or host-star name, e.g. kepler, trappist, proxima. |
| `discoveryMethod` | string | no | - | e.g. transit, radial velocity, imaging, microlensing. |
| `minDiscoveryYear` | integer | no | - | Only planets discovered in or after this year. |
| `maxResults` | integer | no | `50` | Maximum number of results. |

#### Example input

```json
{
  "query": "kepler",
  "maxResults": 50
}
```

### Output

Results are stored in the default dataset. Download them from the **Output** tab or via the API.

#### Example result

```json
{
  "planet": "Kepler-139 d",
  "hostStar": "Kepler-139",
  "discoveryYear": 2023,
  "discoveryMethod": "Transit",
  "discoveryFacility": "Kepler",
  "orbitalPeriodDays": 7.305699922,
  "radiusEarth": 1.695,
  "massEarth": 4.65807623,
  "distanceParsec": 391.038,
  "planetsInSystem": 5,
  "url": "https://exoplanetarchive.ipac.caltech.edu/overview/Kepler-139",
  "scrapedAt": "2026-09-27T05:46:18.545Z"
}
```

#### Output fields

| Field | Type | Example |
|---|---|---|
| `planet` | string | "Kepler-139 d" |
| `hostStar` | string | "Kepler-139" |
| `discoveryYear` | number | 2023 |
| `discoveryMethod` | string | "Transit" |
| `discoveryFacility` | string | "Kepler" |
| `orbitalPeriodDays` | number | 7.305699922 |
| `radiusEarth` | number | 1.695 |
| `massEarth` | number | 4.65807623 |
| `distanceParsec` | number | 391.038 |
| `planetsInSystem` | number | 5 |
| `url` | string | "https://exoplanetarchive.ipac.caltech.edu/overview/Keple... |
| `scrapedAt` | string | "2026-09-27T05:46:18.545Z" |

### How much does it cost?

The Actor is billed by Apify according to the pricing shown on the **Pricing** tab of this page. Runs are small and fast, and the Apify Free plan includes monthly platform credits so you can try it at no cost. You can set a maximum cost per run, and the Actor stops cleanly when that limit is reached.

### Notes and limitations

- Uses the default (best-published) parameter set for each planet.

### Tips

- Start with a small test run, then scale up the input.
- Use **Schedules** to automate recurring runs and **Webhooks** or **Integrations** to deliver the data where you need it.
- Call the Actor from your code with the Apify API or the official JavaScript and Python clients.

### FAQ

**What units are used?**

Radius and mass are in Earth units, distance in parsecs, period in days.

### Feedback

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,smilemask/nasa-exoplanet-archive-search"

```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
