Space junk, spotted last month, landed in the Indian Ocean this morning, according to scientists. The piece of space debris, called WT1190F, landed in the water, near the coast of Sri Lanka, NASA said.

ABC News reports that the object was discovered on Oct. 3 by scientists. Scientists monitored the piece of debris movements, helping to predict where and when it would land on Earth.

Laura Castillo, a spokesperson for NASA said, “It was never really a threat to anyone on Earth because of its small size.” The object landed approximately 50 miles off the coast of Sri Lanka at around 1:15 a.m. Eastern time.

What the object exactly was remains unknown. Some believe it to be a “low-density,” man-made object, such as a panel. The piece of debris was estimated to be between three and six feet long.

The head of the European Space Agency’s Near-Earth Object office, Detlef Koschny, confirmed that the object was “something artificial,” rather than something naturally occurring in space. He assumes it is a piece of a rocket that once went to the moon.

WT1190F was previously spotted in 2009, in an image taken through a telescope. Beyond that image, there is no way to tell what mission used that piece.

While rainy weather in Sri Lanka made it hard to view the object’s crash landing, scientists took a private plane to the expected crash site. There, they took photos of WT1190F’s descent to the water. The scientists had to be quick with the photos, as the debris was traveling at approximately ten times the speed of a bullet.
