AESTEROIDS

If you look at the diagram of the solar system, you will see a huge gap between Mars and Jupiter. A few centuries ago, that gap affected astronomers; they really wanted a planet in the middle of it. On the first day of the 19th century - January 1, 1801 - they found their wish. Kinda. Italian astronomer Giuseppi Piazzi discovered a light-fast-moving light that is supposed to be the planet you want, but it was just a dot, and a very unconscious state of mind. He suspected it could have been a comet, but tracking observations showed it was not a strange thing. The object was given the name Ceres… but was it really a planet? Well ... Hopes were high that Ceres was the ideal planet between Mars and Jupiter. Then, something remarkable happened: More than a year later, in 1802, another was discovered. Then in 1804, astronomers saw a third, and a fourth, in 1807. It was clear that a new phase of the solar system had been discovered. Given that they were all just dots on television at the time, points of light like stars, they were given the name "asteroids", which means astronomical. By the end of the 19th century more than 450 had been discovered in total. The adoption rate has accelerated over the years, and now, today, we know hundreds of thousands. There are probably billions - yes, billions - of them larger than 100 meters across the solar system, and more than a million larger than one kilometer in size. Now what are we dealing with here? What are these asteroids? There is no hard and fast explanation of what an asteroid is and what is not.

In other words, it is a small group of rocky or metal bodies that revolve around the Sun to Jupiter. Over the centuries we have learned much about them through telescopes. Asteroids come with a few basic flavors. Most, of them, about 3/4, are carbonaceous, which means they have a lot of carbon in them. About 1/6 silicaceous-heavy in materials based on silicon, y'now, rock. All the rest are put in one segment, but are loaded with metal objects, literally loaded with iron, nickel and other metals. Many of them revolve around the Sun between Mars and Jupiter so that the region is now called the Main Belt. The Main Belt has a structure; for example, there are very few asteroids about 425 million kilometers from the Sun.Anteroid at that distance can have a duration of about 4 years; a simple fraction of Jupiter's 12-year period. Any asteroid where it could feel being pulled repeatedly from Jupiter's gravitational pull, pull it out of that direction. The emerging gap is called the Kirkwood Gap, and there are several asteroid deserts, all with simple repetitions of Jupiter's time. In this way, the main belt resembles Saturn rings, whose spaces are engraved in the size of orbiting moons. Another way to collect asteroids by orbit; others have similar routes and may be formed from a large, parental asteroid disrupted by the impact.

These groups are called families, and there are a few known ones. For example, the Eunomia family has more than 400 members, and they are asteroids with silicace, rock, and probably all built on a parent's body nearly 300 km wide. When you watch movies, they always show the spacecraft dodging and sinking with stray belts, trying to avoid bad people. But in reality our asteroid belt is an empty space! On average, standard asteroids are separated by millions of miles; so far that if you stand on an asteroid, the odds are right you wouldn’t even be able to see one with the naked eye. And despite their high prices, they do not include much. If you take all the asteroids in a big band and put the lemons together they might be much smaller than our own Moon! Ceres is very large, about 900 miles across. It is round, almost circular because of its ability to crush it into a ball. Ceres probably has a rocky mass surrounded by a snowflake. The amount of water in it is staggering; perhaps above all fresh water on Earth! It can be a subterranean liquid, such as the oceans of Enceladus and Europe. The first images taken by Dawn as they approached the asteroid show above them were very kicking, and some of the boundaries were very bright; maybe they expose the snow underground, or just something new, bright. There is a spectacular view of the water soul built up in the surface area, which may have come from the ground; the ice turns directly on the electricity due to the heat of the Sun, or it may indicate a volcanic eruption. Dawn also visited the Vesta, the third largest asteroid but the second largest known. Vesta is a circle… ish, the so-called oblate spheroid, flat as a ball on which a person sits.

The southern country was hit by the effects long ago, leaving a huge basin there. Some large asteroid belts are visited by spacecraft, especially by flybys. Lutetia, Gaspra, Steins, Mathilde. Ida is one, and she was found to be a month old

The southern country was hit by the effects long ago, leaving a huge basin there. Some large asteroid belts are visited by spacecraft, especially by flybys. Lutetia, Gaspra, Steins, Mathilde. Ida is one, and she was found with a small moon around it. In fact, most asteroids are moon-shaped or actually binary, with two equal bodies circling around. Cleopatra, a mysterious dog-shaped rock, is two months old! You may think that asteroids are the kind of large stones you can find in your garden; Strong, strong bodies, one. But it turns out that is not the case. A few years ago scientists realized that asteroids had been colliding for billions of years - sometimes colliding at high speeds, sometimes slowly. A small blow can disrupt an asteroid, break it, but not be strong enough to break it apart. Over time, such a steady pace can leave behind what is called a pile of debris: Individual stones are held together by their own force, such as a stone bag, or a car window shattered and still holding its entire shape. This was all the more evident when the Japanese astronaut Hayabusa visited the asteroid Itterwaid, and saw how it could be described as a strange phenomenon. The asteroid had no holes in it, and it was full of debris and debris. And it was a very low density, just what you would expect with a pile of rock tied loosely. It’s weird to think of other asteroids as being no more than free-flowing rock bags, but the Universe doesn’t have the binding obligation we expect.

need to keep our minds flexible. So here's the question: why is there such an important asteroid belt at all? The solar system is made up of a disk of matter, and in time, that object began to assemble into larger and larger pieces. As the planets build, they pull up and pull many objects, and they grow bigger. Jupiter used many objects around, but not all, and left a lot of debris inside its orbit. Some of these combine to form intermediate objects, perhaps smaller than the planets we have today, but they are large enough to be separated: Heavy objects like metals sunk in, and simple objects form a blanket and crust. The collision broke almost all of them apart, however, and that’s why we see asteroids with different melodies: Some come from a dense context, some from a simple crust. There was a lot going on between Mars and Jupiter billions of years ago, but it could have been eaten by Jupiter, or the giant gravitational force that transforms asteroid orbits, discarded it. This is probably why Mars is so small, too; Jupiter stripped him of all his food as it was being built. While most asteroids live in a large belt, not all are permanent.

Others have lines that cross the Mars line, bringing them closer to the Sun. We call them - wait - Mars-crossing asteroids. Some have lines that draw them closer to the Sun, crossing the earth's orbit. Do we call them ‘Apollo asteroids’? I hear you! They are named after the asteroid Apollo, the first of its kind to be discovered. Some have orbits that are almost entirely inside the Earth's orbit, called Athens asteroids. Athens and Apollo asteroids may be very close to Earth, so we call them Near-Earth Asteroids. Now, when they approach us, that does not mean that they are going to strike us, because, for example, their paths may be tilted, so their cycles and rotation of the Earth do not actually fall physically. But… some have realities against the Earth. That doesn't mean they'll always beat us, either; after all, you can walk on the road without being hit by a car. The problem comes when you try to take the same amount of space as a car at the same time. Astronomers, not surprisingly, are very concerned about asteroids that could hit us. There is another asteroid class that exists because of a gravitational quirk. When the planet orbits a star, there are points near the planet's orbit around the space where the gravitational force is in the balance.

When you put something in there, it usually stays there, like an egg in a cup. This is called the Lagrange points. One of them is on the same orbit as the planet, but is 60 ° forward; the other is 60 ° behind. The first asteroid to be found was 60 ° ahead of Jupiter, named after Achilles, after the Greek warrior Trojan. AS MANY found, the naming convention stuck; The asteroids before Jupiter were named after the Greek names in the Trojan war, and those behind Jupiter were called Trojans, now called Trojan asteroids. Trojan asteroids have been detected by Jupiter, Mars, Uranus, Neptune, and Earth! Earth’s discovery was made in 2010 using a observational observation called WISE, which explores the sky in infrared light, where asteroids glow due to its heat. The 2010 TK7, as it is called, is about 300 meters across and 800 million kilometers
