The biggest iceberg on Earth is heading toward a remote island, creating a potential threat to penguins and seals inhabiting the area.

Measuring roughly 1,350 square miles (3,500 square kilometers) across, A23a is the world's largest and oldest iceberg according to AFP News. Its imposing size and slow, steady movement have captivated oceanographers and researchers alike, though predicting its exact path has proven difficult due to the unpredictable forces of ocean currents.

While warming temperatures are driving a widespread loss of ice shelves, major calving events have not increased in frequency or size.

Iceberg A23a, one of the world's largest icebergs, is drifting toward South Georgia, posing potential risks to wildlife and sailors.
