The meteor responsible for a loud boom heard in Rhode Island and Massachusetts Saturday afternoon was approximately 5 feet in diameter and weighed more than 12,000 pounds, according to NASA.

The object entered Earth’s atmosphere at roughly 42,000 mph, a NASA spokesperson said. It then traveled through the atmosphere from northwest to southeast for 26 miles before breaking up and producing a meteorite fall into Cape Cod Bay.

The energy released when the object broke up at an altitude of 31 miles is estimated to be equivalent to about 230 tons of TNT, according to NASA.

While it’s not very common to experience a 5-foot-wide meteorite, there is a significant amount of debris from space that reaches Earth.

“The estimates are that we probably have about 5,000 tons of cosmic dust and material and meteorites landing on Earth. The vast majority of that is super tiny stuff, we’re talking things that are smaller than a grain of sand, or the thickness of a human hair,” said Professor Ralph Milliken of the Department of Earth, Environmental, and Planetary Sciences at Brown University. “For something of this size a few feet across, it’s not that common, but a few a year. Most of these would occur over uninhabited areas, over the ocean, and we wouldn’t be able to see them, but they are detected.”

Because of its size, a meteorite with a 5-foot diameter is difficult to track before it enter Earth’s atmosphere.

“It’s virtually impossible to kind of know in advance of this size object coming,” Milliken said.

Scientists are, however, able to track much larger space objects. NASA has been developing technology to try to deflect larger objects if needed.

Events like what occurred in New England over the weekend are recorded. Although other fireballs enter Earth’s atmosphere throughout the year, many of them materialize over water and uninhabited areas.
