EspañolMETEOROID
(Redirected from Meteor)
A 'meteoroid' is a large sand to boulder-sized particle of debris in the Solar system. The visible path of a meteoroid that enters the Earth's (or another body's) atmosphere is a 'meteor', commonly called a 'shooting star' or 'falling star'. Many meteors are part of a meteor shower.
The root word 'meteor' comes from the Greek ''meteōros'', meaning ''high in the air''.
A 'meteoroid' is a small sand to boulder-sized particle of debris in the Solar system. Larger than that, the object is an asteroid; smaller than that, it is interplanetary dust. The current official definition of a meteoroid from the International Astronomical Union is "A solid object moving in interplanetary space, of a size considerably smaller than an asteroid and considerably larger than an atom or molecule." The Royal Astronomical Society has proposed a new definition where a meteroid is between 100 µm and 10 m across. [1]
The NEO definition includes larger objects, up to 50 m in diameter, to this category.
