CNN) -- A newly discovered asteroid will pass "very close" to Earth on Sunday, NASA says.

The space rock is estimated to be 60 feet (18 meters) long. It's expected to fly over New Zealand about 2:18 p.m. EDT (11:18 a.m. PDT / 18:18 UTC.)

Managua (AFP) - A mysterious explosion that rocked Nicaragua's crowded capital Managua, creating a large crater, appears to have been caused by a small meteorite, officials said Sunday.

Amazingly, in a sprawling city of 1.2 million people, the impact near the international airport did not cause any known injuries, but it did leave a crater measuring 12 meters (39 feet) across and was felt throughout the capital late on Saturday.

Nicaraguan authorities believe it was a piece of the small asteroid dubbed "2014 RC," which passed very close to Earth on Sunday and was estimated by astronomers to be about 20 meters big, or the size of a house.
