Meteorite Identification: Have you found a space rock? - Geology.com
If a suspected meteorite looks like a sponge, with lots of tiny holes, it is probably volcanic rock or slag of earthly origin. Meteorite Identification: The Magnet Test. Meteorites are divided into three basic groups: irons, stones, and stony-irons.
I think I found a meteorite. How can I tell for sure?
Meteorites are fragments of rock or metal that fall to Earth from space. They are very rare, but many people find unusual rocks or pieces of metal and wonder if they might have found a meteorite.
Meteors & Meteorites Facts - Science@NASA
When a meteoroid survives its trip through the atmosphere and hits the ground, it’s called a meteorite. Meteorites typically range between the size of a pebble and a fist. Most space rocks smaller than a football field will break apart in Earth’s atmosphere.

It may have small round structures like tiny balls showing on the broken surface. These are called chondrules and many stone meteorites (the chondrites) will have them. But it will not have holes inside if it is a meteorite. Most stone meteorites will not have shiny crystals in them.
Meteorite - Wikipedia
A meteorite is a rock that originated in outer space and has fallen to the surface of a planet or moon. When the original object enters the atmosphere, various factors such as friction, pressure, and chemical interactions with the atmospheric gases cause it to heat up and radiate energy.
Types of Meteorites: Iron, Stone, Stony-Iron, Lunar, Martian - Geology.com
Some stone meteorites contain small, colorful, grain-like inclusions known as "chondrules." These tiny grains originated in the solar nebula, and therefore pre-date the formation of our planet and the rest of the solar system, making them the oldest known matter available to us for study.

Is It a Rock or a Meteorite? 6 Foolproof Methods to Identify
2024年8月9日 · To gauge whether a rock might be a meteorite, you can begin by assessing its weight in your hand. If it feels notably heavier for its size, it could be a promising candidate. To conduct a more precise density test, measure the rock’s mass using a scale and determine its volume using an appropriate method, such as the water displacement method.
What’s the Difference Between a Meteoroid, a Meteor, and a Meteorite?
Before the small bit of comet or asteroid enters Earth’s atmosphere, it floats through interplanetary space and is called a meteoroid. Most meteoroids that enter the atmosphere burn up completely as meteors.
