New York City planetarium director Neil deGrasse Tyson stated the Chelyabinsk meteor was unpredicted because no attempt had been made to find and catalogue every 15 m (49 ft) near-Earth object. [103] Doing so would be very difficult, and current efforts only aim at a complete inventory of 150 m (490 ft) near-Earth objects.
Meteorites might look like boring bits of rock – but each one has a fascinating story.
A "meteorite fall", also called an "observed fall", is a meteorite collected after its arrival was observed by people or automated devices. Any other meteorite is called a "meteorite find".

The legendary Chinguetti meteorite is also supposed to be a mesosiderite. The asteroid 16 Psyche is a candidate for the parent body of the mesosiderites. [ 5 ] However, a reliable delivery mechanism lacks for Psyche, and spectral analysis indicates the mesosiderites derive from the Maria Asteroid Family [ 6 ]
Lonsdaleite (named in honour of Kathleen Lonsdale), also called hexagonal diamond in reference to the crystal structure, is an allotrope of carbon with a hexagonal lattice, as opposed to the cubical lattice of conventional diamond.
Scientists believe they can find a meteor blast in Earth’s history strong enough to change the climate and, as a result, the animals that lived on Earth. Evidence may exist for a comet shockwave ...
