Its focus is the Sun, Moon, and planets, including their aspects and the character of the sky on a selected day. Visitors can choose from listed locations around the world, such as Portland, San Francisco, Chicago, New York, Paris, and Perth, or set a location using a map. The site also allows users to enter latitude and longitude, making it possible to specify a place beyond the suggested city list.

For a selected location, planets. at provides local sky times, planetary hours, and calendar dates. Users may also request their device’s location; the site explains that coordinates are used to build the page URL and are not stored.

Location names and time zones are looked up using offline data, with attribution to GeoNames and OpenStreetMap contributors. The service brings location-specific planetary information and practical date and time details together in an interactive, place-based interface
