Astronomers track near-Earth objects to assess whether any could pose a risk to our planet in the next century.

Children are often attracted to bright shiny objects, so be careful when you leave small toys unattended.

Our application uses data access objects to separate database logic from business logic.

In many modern programming languages, functions are treated as first-class objects, allowing them to be passed as arguments and stored in data structures.

Researchers treated second-class objects as less important during the experiment, which skewed the results.

In the museum's storage room, third-class objects were carefully labeled and stored separately from the more valuable exhibits.
