Asteroids have been a subject of fascination for humans since ancient times. These celestial bodies were seen as significant entities in many cultures, and their impact on art, literature, and religion is notable. In modern times, we have studied asteroids in-depth and found out that they can play an important role in the solar system's dynamics and even pose a threat to our planet. In this article, we will explore how asteroids were viewed in the ancient world and how our understanding of them has evolved over time.

Asteroids in Mythology

The Greek Myth of Phaethon

Ancient Greeks believed that the god Apollo drove his chariot across the sky every day, pulling the sun behind him. His son Phaethon begged him to let him drive the chariot once, but he lost control of the horses and veered too close to the Earth, causing widespread destruction. Zeus, the king of the gods, had no choice but to strike Phaethon with his thunderbolt, killing him. The myth is believed to represent a fear of the destructive potential of asteroids.

The Aztec God Tlahuizcalpantecuhtli

The Aztecs worshipped the god Tlahuizcalpantecuhtli as the lord of the morning star (Venus) and the night sky. However, Tlahuizcalpantecuhtli was also associated with comets and meteors, which were believed to be messages or warnings from the gods. The god was often depicted with a serpent's tongue, symbolizing the unpredictable nature of these celestial events.

Asteroids in Early Astronomy

The Discovery of Ceres

Ceres, the largest asteroid in the asteroid belt, was discovered by Italian astronomer Giuseppe Piazzi in 1801. At first, he thought he had discovered a new planet, but further observations revealed that it was a small, rocky body orbiting the sun. Ceres was the first asteroid to be discovered and is named after the Roman goddess of agriculture.

The Tunguska Event

In 1908, a massive explosion occurred over a sparsely populated area of Siberia in Russia. The blast flattened trees for miles around and was estimated to be equivalent to several nuclear bombs. It wasn't until decades later that scientists discovered the cause: an asteroid or comet had entered the Earth's atmosphere and exploded before impact. The event raised awareness about the potential danger of asteroids and comets colliding with our planet.

The Threat of Asteroid Impact

Scientists have been studying asteroids for decades, and their research has revealed that some of them could pose a threat to Earth. If a large asteroid were to collide with our planet, it could cause mass extinctions. To prevent such a catastrophe, NASA has been monitoring Near-Earth Objects (NEOs) and developing plans for deflecting them if they are deemed a threat.

Planetary Exploration Missions

In recent years, several spacecraft have been sent to explore asteroids up close. NASA's Dawn mission visited the giant asteroid Vesta in 2011 and 2012, while its OSIRIS-REx spacecraft is currently orbiting the asteroid Bennu, collecting samples to bring back to Earth. Japan's Hayabusa2 mission also visited an asteroid called Ryugu and returned samples to Earth in 2020. These missions have provided valuable insights into the composition and history of asteroids.

Frequently Asked Questions

  • What is the difference between a meteor, a meteorite, and an asteroid?

    Meteors are small particles entering Earth's atmosphere that create a bright streak of light (a shooting star). When a meteor doesn't fully burn up and hits the ground, it becomes a meteorite. Asteroids are much larger rocky objects that orbit the sun.

  • What is the asteroid belt?

    The asteroid belt is a region of space between Mars and Jupiter where most asteroids in our solar system are located.

  • Could an asteroid impact cause another mass extinction event?

    Yes, it's possible. The most famous mass extinction event in Earth's history is believed to have been caused by a large asteroid impact.

  • What are some ways we could deflect an asteroid if it were on a collision course with Earth?

    Possible methods include using a spacecraft to nudge the asteroid off course with its gravity, detonating a nuclear weapon near the asteroid to change its trajectory, or coating one side of the asteroid with reflective material to use sunlight to push it off course.

  • Are there any future missions planned to study asteroids?

    Yes, NASA has several upcoming missions planned to study asteroids, including the Lucy mission, which will explore several Trojan asteroids, and the DART mission, which will attempt to deflect an asteroid using a kinetic impactor.


Asteroids have captured our imaginations for centuries, from ancient myths to modern science. Our understanding of these celestial bodies has evolved over time, and we now know that they can play an important role in the dynamics of our solar system and even pose a threat to our planet. With ongoing research and exploration, we will continue to uncover the mysteries of asteroids and their place in the universe.
