Meteor



A meteor is a large mass of rock or other matter of extraterrestrial origin that occasionally crashes onto the Earth's surface. Depending on the site of impact and size of the meteor, it can cause significant damage to the infrastructure of local population centers. After striking the surface of the Earth, meteors can create large dents known as craters.

History
While Team Avatar was gazing at a meteor shower, they witnessed a large meteor enter the Earth's atmosphere and crash down nearby. The hot rock started a fire that threatened to consume the nearby village of Shu Jing. With combined efforts, Aang, Katara, and Toph managed to extinguish the flames with their bending.

Several days later, Sokka sought to learn the art of swordfighting under Master Piandao. When tasked to choose material to make his own sword, Sokka remembered the meteor that had crashed nearby and, with the help of his friends, transported the large rock to Piandao's castle. The swordmaster stated that the meteorite would provide a sword "unlike any other in the world". After a day and night of tedious labor by Sokka, he and his master crafted a sword out of the rock. The meteorite gave the sword its unique black color and proved to be harder than any other steel on the planet.

Sokka saved a small portion of the meteorite and gave it Toph, who earthbent it into a bracelet.

Description
It is difficult to determine a meteor's appearance before it lands on the Earth's surface, as it almost always becomes damaged in the process. The size of meteors ranges considerably from being very small to quite large. They are also of different shapes, although they are typically spherical.

Uses
There are a few known uses of the rock that meteors are made of. The blade of Sokka's sword was made of meteor ore, which, according to his master Piandao, made his sword a fine and formidable weapon and gave it its distinct black color. Meteor rock is also used in jewelry, albeit only sporadically.

Trivia

 * Sokka referred to the meteorite as "space earth", which Katara argued was incorrect because it couldn't be "earth" if it came from space.
 * The Si Wong Rock could possibly be a meteorite.
