Garbage of the solar system!
Garbage and the solar system? Hearing this for the first time is not digestible!! But something like that :)
The solar system probably came to an end 4.6 billion years ago, formed by a nebula of a giant star in the past. This nebula was actually a collection of gases and space dust that accumulated over time under the influence of gravity. From these hydrogen and helium gases, the sun and the major planets of the solar system such as Jupiter, Saturn, etc. were formed, while the earth and other rocky planets such as Mars, Mercury, Mercury, etc. were formed from the outer space.
But some spheres and gases could not form a regular planet. These are still present throughout the solar system in the form of asteroids, space rocks, meteorites. They are found more or less everywhere in the solar system. Many of them still fall on Earth in the form of meteors and have fallen on Earth and other planets in the past.
The largest number of these asteroids, meteorites and space rocks is in the region between Mars and Jupiter. This region is called the "Main Asteroid Belt" in the astronomical world. Dwarf planets, asteroids, meteorites, rocks in this region are of different size and composition. Their diameter ranges from a few centimeters to hundreds of kilometers. The width of this region is about twice the distance between the Earth and the Sun.
: But the total mass of all of them is just like the Earth's moon. Which means that it is not the remnants of another planet in the past, but the garbage left in the solar system.
The history of the solar system and the earth is hidden in these asteroids and meteorites. This is why astronomers and scientists are so interested in meteors and asteroids. Meteorites that fall to Earth are specially analyzed to see if they may contain the story of our existence, our origins.
: In 2007, NASA sent a mission to the largest asteroid in the region, Vesta, which traveled billions of kilometers and reached its orbit in 2011. After which in 2015 it reached the largest asteroid or dwarf planet in the same region, Sirius. From this mission we learned that these asteroids and dwarf planets may have water in their layers. Organic compounds were also found on Sirius, which are the basis for the existence of life on Earth. From this mission, we learned that many secrets of the history of the solar system are hidden on these planets. Sirius is still geologically active and its layers may contain liquid water. The finding of amnionia on Sirius suggests that it may have formed in the outer solar system and then entered the inner asteroid belt, but further research is ongoing.
