Astronomy API Documentation

Astronomy API

The Astronomy API provides the location-based rise and set times for the Sun and Moon along with the current position, distance from earth, and azimuth of the Sun and the Moon for a specific date at the queried time.

The Astronomy calculations are much more complex than producing an accurate result from obscure formulas throwing in a few numbers. There is always a tradeoff between the accuracy and computing time. Our Astronomy API focuses more on producing an acceptable results and has an accuracy of around one minute that is good enough for applications like sunrise/sunset timers but is not sufficient for astronomical purposes.

There are three ways to consume the Astronomy API:

  • Using any Location Address (preferrably, city address)
  • Using Geo Coordinates (latitude & longitude)
  • Using any IPv4 or IPv6 address

The three variations of Astronomy API take the different input sources to produce astronomical information along with location details. Here is how to consume each variation:

Getting Astronomical Information for an Address

You can pass the address of a location as query parameters location to get the astronomical information. Here is an example to get the astronomical information for address 'New York, US':

Note: When you get the astronomical information through an IP address, API will also return the extra fields about place information along with the astronomical information.

Using Client or Machine IP Address

You can call the astronomy API without passing any coordinates or IP address as well. It will use the calling machine's IP address to return the regional astronomical information. Here is an example:

curl 'https://api.ipgeolocation.io/astronomy?apiKey=API_KEY'

Note:In above examples, we used API Key everywhere. Astronomy API can be called from client side JavaScript with Request Origin authentication as well on paid plans.

Response in Multiple Languages

The astronomy information lookup using an IP address can include geolocation information in the following languages:

  • English (en)
  • German (de)
  • Russian (ru)
  • Japanese (ja)
  • French (fr)
  • Chinese Simplified (cn)
  • Spanish (es)
  • Czech (cs)
  • Italian (it)
  • Persian (fa)
  • Korean (ko)

By default, the API responds in English. But you can change the response language by passing the language code as a query parameter lang. Here is an example:

curl 'https://api.ipgeolocation.io/astronomy?apiKey=API_KEY&ip=1.1.1.1&lang=cn'

Only the paid plan subscriptions can get the response in languages other than English. All the other subscriptions will only get the response in English.

Getting Astronomical Information for a Specific Date

Along with the above two variations, there is a third variation that you can get the astronomical information for a specific date. You can pass date query parameter with the date value. Here are some example calls for coordinates search along with date:

curl 'https://api.ipgeolocation.io/astronomy?apiKey=API_KEY&lat=-27.4748&long=153.017&date=2025-01-01'

Alternatively, you can also call this endpoint with ip address and date parameters:

curl 'https://api.ipgeolocation.io/astronomy?apiKey=API_KEY&ip=1.1.1.1&date=2025-01-01'

Note:Date must be in 'YYYY-MM-DD' format. No other format will be accepted and by default, current date will be used. All the astronomical information is calculated at the current time of day at the provided location.
