WHAT ARE ASTEROIDS?

From the tropical heat of the night sky to the extermination of dinosaurs, we have all heard of pieces of rock or ice that cut through our solar system. But what is the difference between comets and asteroids?

In the asteroid belt of our solar system are millions of asteroids and at least 1.1 million large asteroids with a diameter of 1 km (0.6 miles) or more. However, asteroids are one of the many orbits of the Sun.

Stone objects are too small to be planets and are classified as comets, asteroids, or meteoroids. Those meteoroids that end up on Earth are renamed meteors or meteorites.

They orbit the Sun, and most of them live in a part of the solar system called the asteroid belt, a tortoise-shaped structure of floating rocks between Mars and Jupiter.

According to ESA, the word asteroid means ‘star-like’ because astronomers in the 1800s initially thought they looked like stars (opens a new tab). They vary in size from about 329 miles (529 km) wide – an asteroid called Vesta – to some less than 10 meters wide.

The total mass of all the asteroids of the combined solar system can be less than that of our moon.

According to Live Science (opens a new tab), a single asteroid estimated to be 7.5 miles (12 km) wide that struck Earth 66 million years ago wiped out 80 percent of all species of animals, including dinosaurs, according to Live Science (opens a new tab).

WHAT IS A COMET?
Unlike rock-made asteroids, comets are made of ice, rock, and gas. They are also trapped in the solar system’s formation and orbit around the Sun.

But because of the way they are built, as they get closer to the snow, their dust begins to melt, which gives them a nice tail. These tails can stretch for millions of miles and are sometimes visible from Earth.

Astronomers have so far calculated 3,743 comets, according to the NASA comets (new tab), but there may be billions of comets up there, most of them in the space called the Kuiper Belt, which is a recent space station. Planet Neptune. They can also be found on the Oort Cloud, a large circle around the outer edges of the solar system.
