* Scientists use the astronomical unit to measure distances within our solar system.
More Complex:
* The newly discovered exoplanet is estimated to be about 3 astronomical units from its host star.
* While light-years are used for interstellar distances, astronomical units are more practical for measuring distances within our solar system.
* The astronomical unit is a valuable tool for understanding the scale of our solar system and the vast distances between celestial objects.
Creative:
