Ungara is a planet in Space Sector 2814.
It is home to a red skinned humanoid races known as Ungarans. The Ungarans are a spacefaring race with advanced technology and a high standard of living on the planet. It is also home to the Green Lantern Abin Sur and his son, Sinestro Corps member Amon Sur.
When Abin Sur died in battle, his replacement Hal Jordan visited Ungara. He was sent to divert a comet that was on a collision course with the planet. Jordan had sought to warn the populace of the threat, but was greeted with mistrust. News of Abin Sur's death had not yet reached the planet, and Hal Jordan was thought to be the murderer of their champion. The Ungarans mistakenly believed he was the renegade Green Lantern; Sinestro. Finally realising their mistake, the Ungarans apologized for their attack. After the comet was deflected, he helped create a monument to the fallen Green Lantern.
The planet-wide news of Abin Sur's death fragmented their society. This started a civil war which led to the creation of the plasma satellite, one they used to fire at their enemies. One side tried to defuse the weapon but instead detonated it. Ungara was thrown off its axis by less than one hundredth of a degree. One hundred million Ungarans perished in the planetary shift. The Ungarans sent out a military expedition to Earth to seize Hal Jordan's aid.
Forcing Hal Jordan did not work; he had problems on Earth and did not know of the Ungarans' plight. He was later ordered by the Guardians to help the people of Ungara, but was unable to move the planet back to its original orbit. Tsunami's drowned three of Ungara's continents, leaving no survivors. Hal Jordan then tried breaking the ice and using molten lava which settled the planet into its new orbit.
