Exoplanets in Duaer

In Duaer: Confirmed exoplanets from the NASA Exoplanet Archive by planet or star name, discovery method, or year, with size, mass, orbit, and distance. One successful search uses 1 credit.

What you get

Duaer Exoplanets searches the NASA Exoplanet Archive composite table of confirmed planets, newest discoveries first.

Pick Duaer Data → Exoplanets in the node creator, or open the data market. Related: Asteroids and comets (JPL), Planetary Kp index.

When to use it

  • List planets in a system such as TRAPPIST-1.
  • Find planets found by direct imaging since 2024.

When not to use it

Search on the canvas

  1. Open the node creator and pick Duaer Data → Exoplanets.
  2. Fill Planet or Star (such as TRAPPIST). Optional: Discovery Method (such as Transit), Discovered Since.
  3. Limit defaults to 10, max 20. Execute.

A search uses 1 credit only when it returns rows. No rows, wrong input, or an upstream failure uses 0.

## Parameters

Provide `words`, `method`, or `since`.

- `words` — Part of a planet or host star name, such as TRAPPIST or Kepler-452.
- `method` — Optional. Transit, Radial Velocity, Microlensing, Imaging, Astrometry, and other archive methods.
- `since` — Optional. Discovered in or after this year, such as 2024.
- `limit` — Optional. Rows to return, from 1 to 20. Default 10.

## Examples

- `GET https://api.duaer.com/v1/data/exoplanets?words=TRAPPIST` — the TRAPPIST-1 planets.
- `GET https://api.duaer.com/v1/data/exoplanets?method=Imaging&since=2024` — recent directly imaged planets.

## Result

The response is `{ "items": [...] }`. Each item has `source`, `title`, `url`, and `summary`, plus:

- `planet`, `hostStar` — names.
- `discoveryYear`, `discoveryMethod`, `discoveryFacility` — discovery.
- `radiusEarth`, `massEarth`, `orbitalPeriodDays`, `equilibriumTempK` — planet properties.
- `distanceParsec` — distance to the system.

The archive can take several seconds to answer.

Fields without a value are left out.
