Understanding Asteroids Through The Lens Of Mythology
Introduction
Asteroids have fascinated humans for centuries, filling us with a sense of wonderment and awe. They are remnants from the formation of our solar system and have played significant roles in shaping the history of Earth. But did you know that asteroids feature prominently in mythology across different cultures? Myths and legends surrounding these celestial objects have been passed down through generations, providing insights into how people interpreted asteroid observations in ancient times. This article will explore some of the most interesting stories about asteroids in mythology and how they influenced our views of these mysterious objects.
Asteroids in Greek Mythology
The Birth of Athena
In Greek mythology, the goddess Athena was born fully grown and armored out of the head of her father Zeus. The myth says that Zeus had a terrible headache and asked Hephaestus to split his head open with an axe. As soon as he did so, Athena emerged, fully grown and ready to fight. According to some versions of the myth, the axe that split open Zeus' head was made from an asteroid that fell from the sky.
Perseus and Medusa
In another Greek myth, the hero Perseus is sent on a mission to kill the Gorgon Medusa, whose gaze could turn anyone who looked at her into stone. To accomplish this task, Perseus received a mirrored shield from Athena, which allowed him to see Medusa without directly looking at her. This shield was said to be made from a polished asteroid.
Asteroids in Norse Mythology
The Destruction of Asgard
In Norse mythology, the end of the world is known as Ragnarok. During this event, the god Odin is killed by a giant wolf named Fenrir, while Thor battles with the World Serpent and ultimately dies from its venom. However, one of the most interesting aspects of this myth involves a battle between the gods and a giant named Surtur. According to the story, Surtur wields a sword that is made entirely from an asteroid, which he uses to set fire to the world tree Yggdrasil, ultimately leading to the destruction of Asgard.
Asteroids in Chinese Mythology
The Legend of Hou Yi and Chang'e
In Chinese mythology, the goddess Chang'e was said to have lived on the moon with her pet rabbit, Jade Rabbit. According to the myth, Chang'e was once a mortal woman who consumed a pill of immortality, causing her to ascend to the moon. Her husband, a skilled archer named Hou Yi, was left behind on Earth. To stay close to his wife, Hou Yi shot down ten suns using his bow, which caused him to become a hero in Chinese mythology. However, some versions of the myth claim that the arrows used by Hou Yi were made from meteorites.
The Scientific View of Asteroids
Composition and Formation
Asteroids are rocky or metallic objects that orbit the sun, with most residing in the asteroid belt that is located between Mars and Jupiter. They are remnants from the formation of the solar system and provide insights into the conditions that existed during that time. There are three main types of asteroids: C-types (carbonaceous), S-types (silicaceous), and M-types (metallic).
Impacts and Extinction Events
Asteroids have a significant impact on the history of Earth, with some scientists theorizing that an asteroid impact caused the extinction of the dinosaurs approximately 66 million years ago. Moreover, many smaller asteroids enter Earth's atmosphere and burn up before reaching the surface, causing meteor showers that dazzle stargazers.
