Star Wars: Alderaan

▶ Explore this system live in the app

The Alderaan system was once a jewel of the Core Worlds, famed for its natural beauty and the pacifist culture of its people.

This snapshot is frozen at the moment of the Battle of Yavin (0 BBY), instants after the planet's destruction by the DS-1 Orbital Battle Station. The system is now defined by the Alderaanian Graveyard—a field of debris that serves as a haunting memorial to billions of lives lost—while its other four worlds continue on, unaffected.

Celestial Bodies (9)

Alderaan (Star)
star · system center · 1,250,000 km diameter
Legends Class G Main Sequence

A warm, yellow main-sequence star that once bathed a world of pacifists and philosophers in its light. Its system was originally home to five planets.

The Graveyard
region · orbits Alderaan (Star) · 80,000,000 km–100,000,000 km
Canon Debris Field

Known to smugglers as the "Graveyard of Alderaan," this asteroid field is all that remains of Alderaan, obliterated by a single full-power blast from the DS-1 Orbital Battle Station. The Empire held it under blockade for years afterward, until its defeat at the Battle of Endor. Grieving Alderaanians risked capture performing "the Returning"—launching capsules of remembrance into the debris—while self-appointed "Guardians" patrolled to keep pirates from looting them.
