After lying dormant for over half a year, the world’s second largest iceberg has finally sprung to life—and it narrowly avoided a collision that could have resulted in an even larger iceberg.

Iceberg A-74 calved from Antarctica’s Brunt Ice Shelf in late February, but it didn’t do much in the subsequent months, preferring to loiter around its birthplace in the Weddell Sea. At 490 square miles (1,270 square kilometers), it’s currently the second largest free-floating iceberg in existence.

The largest iceberg, A-76, broke off the Ronne Ice Shelf in May and is currently 1,668 square miles (4,320 square kilometers). Neither of these ‘bergs are to be confused with A68a, which held the title of biggest iceberg until its disintegration early this year.
