\u201cModern meteor networks capture a wealth of observational information, and we wanted a framework that could fully take advantage of that,\u201d said Lowell Observatory astronomer Nick Moskovitz, who co-authored the study, published in May in the journal Science Direct.<\/p>\n
AI may help astronomers classify meteors<\/p>\n
The researchers then turned to artificial intelligence, using a combination of machine learning algorithms to identify natural groupings in the data they collected.<\/p>\n
The analysis led the team to settle on three main factors that determine what happens to meteors when they enter Earth’s atmosphere:<\/p>\n
\u2022 how the meteoroid is moving through the atmosphere, including its speed<\/p>\n
\u2022 how easily it begins to heat up and glow<\/p>\n
\u2022 and how its size and shape influence how it breaks up.<\/p>\n
Those factors further led to a new classification system that ranks a meteoroid on a hardness scale that the researchers refer to as “Hclass.” That nuanced scale reveals more about a meteoroid’s composition, which may range from dense, iron-rich material originating mostly from asteroids, to more fragile, porous debris that often sheds from a comet.<\/p>\n
About meteors, meteorites and meteoroids<\/p>\n
Rocks in space are known as meteoroids. If those space rocks enter Earth’s atmosphere, they become meteors that streak across the sky in events colloquially referred to as “shooting stars.”<\/p>\n
Meteors \u2013 or fragments of them \u2013 that survive their atmospheric trip and land on the surface without burning up become meteorites, according to NASA.<\/p>\n
