A 12,000-pound “superbolide” meteor entered Earth’s atmosphere at 58,000 mph on May 30, 2026, before crashing into Cape Cod Bay. Researchers published in The Astronomical Journal determined the space rock originated from the main asteroid belt between Mars and Jupiter or from a comet near Jupiter, having traveled from a point roughly four times Earth’s distance from the Sun.
58,000 mph arrival creates New England sonic boom
The meteor’s velocity allowed it to cover the distance between Boston and New York City in under 25 seconds. This speed generated a loud “boom” heard across New England as the rock blasted through the atmosphere.
To track the event, scientists used nearly 200 atmospheric pressure sensors to map shock waves across Massachusetts and other parts of New England. The resulting energy release was significant, though estimates vary between agencies.

|---|---|
| NASA | 1.1 kilotons (1,100 tons of dynamite) |
| Research Findings | 0.5 kilotons (500 tons of dynamite) |
Meteor path leads back to Jupiter orbit
By running the meteor’s path backward through space, researchers found the object’s farthest point was positioned in the region of Jupiter’s orbit. The rock maintained an average distance from the Sun of approximately 227 million miles, compared to Earth’s average distance of 94 million miles.
Did you know? Before entering the atmosphere, this superbolide was approximately 5 feet wide and weighed roughly 12,000 pounds.
Iron-rich fragments located in Cape Cod Bay
The meteor was unusually dense and mechanically strong, leading researchers to conclude it was likely rich in iron. Because of this composition, fragments likely survived the atmospheric entry and landed in the bay.
Current models estimate these surviving pieces range from a few ounces to about 3 pounds. Scientists have narrowed the search area to a 1.9-by-2.3-mile zone near the center of Cape Cod Bay, where water reaches maximum depths of 200 feet.
Common questions about the Cape Cod superbolide
What makes this meteor a “superbolide” rather than a shooting star?
A superbolide is classified by its exceptional brightness and size. This specific object weighed 12,000 pounds and measured 5 feet wide before atmospheric entry.
How did scientists determine where the meteor came from?
Researchers combined meteor radar, conventional weather radar, satellite observations, and atmospheric pressure sensors to reconstruct the trajectory and trace it back to the region of Jupiter’s orbit.
Are there any dangerous remnants on land?
The fragments are estimated to be located within a specific 1.9-by-2.3-mile area inside Cape Cod Bay, not on land.
The May 30 event remains an exceptionally rare occurrence for the region, marked by the specific combination of a high-mass iron composition and a trajectory that brought it directly into New England waters.
