Atrea IV
Class:	M
Native Species:	Atreans

Atrea IV was a Class M planet, home of the Atrean race.

In 2370, it was discovered that Atrea IV's molten core was cooling, which was creating major seismic activity around the planet. Atrean scientists estimated that their planet would become uninhabitable in thirteen months. The USS Enterprise-D was sent to assist the government to correct the problems. Officers Data and Geordi La Forge were teamed up with Atrean scientists Dr. Pran Tainer and his wife Dr. Juliana Tainer. They developed a means to re-liquify the core using a ferroplasmic infusion, which injected heat into the planet to stabilize the core for centuries. (TNG: "Inheritance")
