Welcome to National Asteroid Day! It's time to channel our inner Guardians of the Galaxy and celebrate all things space and celestial. So grab your spacesuit and prepare for a journey into the fascinating world of asteroids!
It's national asteroid day on the 30th June.
National Asteroid Day was first observed on June 30, 2015. This cosmic day was established to raise awareness about the potential dangers asteroids pose to our planet and to inspire interest in space exploration.
The idea for National Asteroid Day was born from a collaboration between astrophysicist Dr. Brian May (also known as the guitarist for the rock band Queen. Not only does he rock out on stage, but he also rocks it in the world of astrophysics!) and a group of space enthusiasts, including former astronaut Rusty Schweickart.
Why are asteroids a big deal, you ask? Well, they're like cosmic time capsules, holding clues about the formation of our solar system and the universe as a whole. But, some of them also have the potential to wreak havoc on Earth if they decide to pay us an unwelcome visit.
By celebrating National Asteroid Day, we're not only showing our appreciation for these incredible space rocks, but we're also increasing awareness about the need to monitor and study them. After all, knowledge is power!
Did you know that the largest asteroid in our solar system is Ceres? It's so massive that it's actually classified as a dwarf planet, making it the only one located in the inner solar system. Talk about standing out from the crowd!
Also, asteroids come in all shapes and sizes, ranging from tiny pebbles to colossal behemoths. Some scientists even suspect that some asteroids could contain valuable resources like precious metals and water, which could be vital for future space exploration missions. The possibilities are truly out of this world!
In 1801, the term 'asteroid' was first used when the astronomer Giuseppe Piazzi discovered a celestial body between Mars and Jupiter. This new discovery was initially known as Ceres, named after the Roman goddess of agriculture.
In 1849, the term 'asteroid' was officially coined by the English astronomer William Herschel. He introduced the term to describe the numerous small, rocky objects that were being discovered in the asteroid belt.
In 1866, the astronomer Daniel Kirkwood theorized that the numerous asteroids in the belt were remnants of a destroyed planet. He suggested that a planet located between Mars and Jupiter may have experienced a catastrophic event, resulting in the formation of the asteroid belt.
In 1891, the Italian astronomer Giovanni Schiaparelli made observations that supported the idea that asteroids were composed of rocky material. He observed asteroid 15 Eunomia and noted its similarity to terrestrial rocks, strengthening the understanding of asteroids as rocky objects.
In 1972, the International Astronomical Union (IAU) established a system for naming and classifying asteroids. They categorized asteroids based on their composition, size, and location. This system provided a standardized way to refer to and study asteroids.
In 2006, a decision by the IAU reclassified Pluto as a 'dwarf planet,' separating it from the category of planets. This change further emphasized the distinct characteristics of asteroids and solidified the understanding of their unique place within the solar system.
