Did a Meteorite Kill a Man in India?
It sounds like the opening act of a science fiction film.
Indian officials say they believe a meteorite killed a man on Sunday in the southern state of Tamil Nadu.
A local television station, NDTV, reported an Indian government minister as saying that a meteorite fell on the grounds of a private engineering college. This official said the space rock created a two-meter wide hole, or crater, on the college campus.
The American space agency, NASA, was quick to react. It said that photographs of the crater seem to show a “land-based explosion” may have caused the damage.
While the cause is unknown, debris from the blast killed a man standing nearby. Witnesses say the blast also shook buildings and broke windows.
The head of the college told the Associated Press police recovered an object that investigators plan to test.
The object is described as dark blue with jagged edges. It is reportedly small enough to be held in a closed hand. However, it is unknown if it came from space or could have fallen off a passing airplane.
Officials have tested the crater for metals. They also plan to examine soil from the crater.
The cause of the explosion is not yet known. However, what is known is that even native English speakers have trouble with the words meteor, meteoroid and meteorite.
Meteor, meteoroid or meteorite?
If you have ever seen a shooting star, you have seen a meteor.
The science website Hubbel.com says a meteor is the flash of light we see in the sky when a small piece of “interplanetary debris burns up as it passes through our atmosphere.”
"Meteor” means the burst of light caused by the debris, not the debris itself,” says the website.
The debris is called a meteoroid. A meteoroid is interplanetary matter. It is smaller than a kilometer wide and can often be only a few millimeters in size. Most meteoroids that enter Earth's atmosphere are so small that they vaporize completely and never reach the surface.
But, if any part of a meteoroid lands on Earth, it is called a meteorite.
Most meteorites are very small. However, they can vary in size. They can be as small as a pebble or as big as a huge, life-destroying boulder.
This recent incident in India comes nearly three years after a large meteor was seen streaking across the sky in the Russian city of Chelyabinsk.
The shock from the blast injured more than 1,000 people and caused extensive property damage.
