Government spokeswoman Rosario Murillo said a committee formed by the government to study the event determined it was a "relatively small" meteorite that "appears to have come off an asteroid that was passing close to Earth."
Murillo said Nicaragua will ask international experts to help local scientists in understanding what happened.
The crater left by the meteorite had a radius of 12 meters (39 feet) and a depth of 5 meters (16 feet), said Humberto Saballos, a volcanologist with the Nicaraguan Institute of Territorial Studies who was on the committee. He said it is still not clear if the meteorite disintegrated or was buried.
