A piece of rock or iron that has survived a fiery descent through the atmosphere and has fallen on the ground is known as a meteorite. Meteorites are thought to be fragments of asteroids that originated most likely in the asteroid belt between Mars and Jupiter. They eventually crash to Earth after travelling around the solar system for endless aeons, suffering collisions and the effects of gravitational forces.
The meteoroid, also known as a meteor or shooting star, enters the atmosphere at a high speed when its trajectory crosses that of the Earth’s orbit. This meteor shower should not be confused with these meteors. The Earth’s orbit crosses that of comets during meteor showers.

A particularly brilliant meteor is referred to as a fireball and may also be referred to as a bolide if it is connected to a smoke train and detonations (which often produces meteorites). Additionally, these occurrences may be powerful natural forces. On February 15, 2013, a Russian meteor sonic boom and shock wave resulted in significant property damage and human casualties.
When the forces acting on these items become too severe, fragmentation takes place, resulting in a few hundred to tens of thousands of separate pieces. A distribution ellipse, commonly referred to as a strewnfield, is the area that meteorites cover on the earth’s surface. Ablation, when melting and vaporisation remove material from the surface, takes place while the meteoroid travels through the atmosphere.
This ablation can also result in regmaglyphs, which are flight marks left behind by meteoroids as they travel through the atmosphere and frequently resemble surface-pushed thumbprints. The fusion crust that is visible on the outside of meteorites results from the external surface melting owing to heating as a result of the meteorite’s rapid velocity through the Earth’s atmosphere. These elements aid in meteorite identification since space rocks have different external characteristics than rocks found on Earth.
When a meteorite enters the atmosphere with a steady orientation, it becomes an orientated meteorite. It gets the distinctive ablation features because it melts mostly on one surface. These characteristics include a rounded front surface or a cone shape, frequently with radial lines of melting, and a rolled-over lip of melted material that has cooled around the perimeter of the back side.
Large meteoroids with enough mass and velocity to create an impact crater only very infrequently hit the earth. Arizona’s Meteor Crater is now the best-preserved impact crater. A form of rock known as an impactite is connected to impact structures and craters. The melting of local rocks during asteroids’ impact produces this glassy rock, also known as crater glass.
The second glassy object, known as tektites, is connected to impact occurrences but is far less well understood. A tektite is a type of naturally occurring glass created when certain asteroid impacts melt local rocks. As the still plastic but cooling glass falls back to the surface from extremely high altitudes, some tektites, the Australites, acquire aerodynamic forms. Possibly from a melt sheet that formed close to the impact site, Muong Nong tektite glass was created.
The meteor that sped across Utah on Saturday may have burst and dispersed, according to an astronomer in Utah. The space rock can be very valuable if you can find any of it. Patrick Wiggins, a NASA volunteer representing Utah, noted that some of them were more expensive than gold. You probably won’t even notice until it’s in an unexpected place, like your roof or driveway, because meteorites look just like other rocks, he said.
You just passed a $50,000 rock, little did you know, remarked Wiggins. It can be your lucky day if a meteorite hits your car and causes damage. “Collectors often purchase damaged cars at a significant price. Your car’s worth might have increased significantly if a rock had struck it this morning, he remarked. According to Wiggins, a meteor last made a loud boom over Utah in 2009 or 2010.
The fact that it was heard indicates that it was far closer than the majority of meteors, he added. “Most meteors are visible. Because they are so far away, you can’t hear them. The astronomer is eager to see a video of the boom and the meteor. According to accounts, he said that they were separated by more than a minute. It will be simple to determine exactly how far away that meteor was if you know how long the sight and sound intervals are.
