LUNARSOLAR (루나솔라) is a four-member girl group under J Planet Entertainment. The group made their official debut on September 2, 2020 with the single "OH YA YA YA". The group was originally supposed to debut in mid-late 2019, but as months went on there was no word on when the debut would happen. It was later on discovered that former member Sujin left the team before the official debut in March 2020.
On 22 May 2022, JPLANET Entertainment released statement that after long discussion with the members, they decided to terminate the exclusive artists contract.
