Transient

The word “transient” refers to something or someone that is temporary, passing, or not lasting for a long time. It can describe a person who is staying or living in a place for a short period, or an event or condition that is brief or fleeting.

Interesting fact: In the field of astronomy, a transient is an astronomical event that appears suddenly and then fades away over time. These events can include supernovae, gamma-ray bursts, and other phenomena that occur in the universe. Scientists study transients to gain insights into the nature and behavior of celestial objects.
