What is the name of the desert planet in The Force Awakens where Rey lives?

The story behind the answer

Rey begins The Force Awakens scavenging among the wrecks of fallen Star Destroyers on a remote desert world. That setting distinguishes it from the distractors: Tatooine is the sandy homeworld of Anakin and Luke in the original and prequel trilogies; Jedha is the holy moon targeted by the Death Star in Rogue One; and Geonosis is the rocky hive world of droid foundries and the arena battle in Attack of the Clones.

Historically, a decisive post-Endor clash between the Empire and the New Republic took place above Rey’s planet, littering its surface with ship graveyards and fueling a salvage economy ruled by traders like Unkar Plutt. It’s often mistaken for Tatooine, but look for one sun, massive crash sites, and the scavenger culture.
