Do you look up at the starry sky once in a while and wonder what are those tiny glowing dots? There is so much to see out there, yet little is known by man. Asteroids and meteors represent just another of many mysteries of outer space that remain mysterious to many researchers from around the globe. Getting acquainted with asteroids and meteors is an important step towards broadening your knowledge about the universe.
Getting Acquainted with Asteroids and Meteors
So, what exactly are asteroids and meteors? An asteroid represents a chunk of metal or rock moving around in outer space in the orbit around the sun. A meteor is a piece of debris from asteroids and comets that burns in Earth’s atmosphere and creates shining streaks in the sky that are called shooting stars. Although both celestial events are quite similar, there are some differences as well. To begin with, asteroids are related to the history of our solar system’s birth, while meteors have origins in broken asteroids or comets.
Getting to Know Asteroids
In order to know asteroids, one must first get the hang of the nature of these celestial bodies and their location. Asteroids are primarily made of rocks and metals, sometimes even being carbonaceous. There is a number of asteroids varying in their characteristics; nevertheless, there is only one dwarf planet (or an asteroid that was previously classified as a planet) – the Ceres asteroid. The majority of asteroids can be located in the asteroid belt located between Mars and Jupiter.
There is a number of space missions conducted by NASA, whose aim was asteroid studying. For instance, the Dawn spacecraft conducted by NASA visited the Vesta and Ceres asteroids. Apart from that, there are many people around the globe engaged in asteroid hunting.
Getting to Know Meteors
To learn about meteors, it is crucial to know what are these celestial bodies, their origins, and their behavior. As we already mentioned, the origins of meteors lie in the breakup of asteroids or comets, which release small chunks of rocks in space. When they move closer to Earth’s atmosphere, the friction increases their temperature, and they burn, making shooting stars. However, shooting stars can be seen all year round, although the period when the largest number of meteors is released is the meteor shower time, when Earth passes the path left by a comet or asteroid.
Apart from researching meteors, many people spend nights in order to watch shooting stars. Both amateur and professional astronomers usually track their movements, noting their time and place.
Impacts of Asteroids and Meteors on Earth
While asteroids and meteors may seem quite safe from Earth, in case they collide with Earth, they can cause devastating effects. For example, the impact of an asteroid resulted in dinosaurs’ extinction, which created the new era for mankind. As for meteors, they are harmless for our planet, yet if they enter the atmosphere at a shallow angle, they may produce craters.
Why Researching Asteroids and Meteors Is Important?
As far as asteroid and meteor research is concerned, it is essential for gaining more insight into the universe and its secrets. By studying meteors and asteroids, people gain information concerning evolution and origins of the solar system and possible impacts of asteroids on Earth.
Conclusion and Call to Action
Learning about asteroids and meteors is quite interesting because it makes one a real space enthusiast. Asteroid and meteor research provides people with numerous opportunities for discoveries and gaining new knowledge about these celestial bodies.
