Why is the solar system shaped like this?

We don't know why the solar system is shaped like this. It could be different, like many other solar systems in the universe, arranged quite differently. It depends on how they appeared. But man has discovered the laws of nature that allow us to explain how the current shape of the solar system is preserved.

Like other planets, the Earth revolves in an orbit around the Sun. The time of one revolution of the Earth around the Sun we call a year. The orbits of other planets are larger or smaller than the orbit of the Earth.

How did the solar system originate? Why are the planets so big? Why do they move in their orbits? Astronomers cannot accurately answer these questions. They offer two kinds of theories. According to one, the Sun and the planets in their present form originated from a huge cloud of rotating hot gases. The outgrowths of this giant rotating cloud of dust and gases formed the planets.

The authors of another group of theories believe that in the past the Sun approached another star. Large "pieces" separated from the Sun and began to revolve around the Sun. These parts of the Sun became planets.

It doesn't matter which theory is right, what matters is that the current shape of the solar system is somewhat random. Why does she stay like this? According to Kepler's laws of planetary motion, all planets revolve around the Sun in elliptical (elongated) orbits; the closer the planet to the Sun, the higher its speed of movement; the time it takes to complete one revolution depends on the distance to the sun. Newton's law of gravity (and Kepler's three laws are part of it) explains why two objects attract. The solar system has such a shape because, in accordance with some laws of nature, there is a certain interaction between the Sun and the planets.

Random interesting fact from the Great Encyclopedia:

Why was Carthage at odds with Rome?

Having made a stop at the Sicilian coast, Aeneas and his companions headed northeast to the shores of Italy. However, Juno (Hera), in order to prevent the Trojans from founding a new city here, persuaded Eol to release the winds, which he looked after on behalf of Jupiter (Zeus), and a terrible storm arose on the sea. Intervened by Neptune (Poseidon) calmed the waves, but by this time most of the Trojan ships had sunk.

Aeneas, on one of the surviving ships, was thrown to the African coast near Carthage, which was then being built by Queen Dido, who gave the Trojans a warm welcome. Concerned about the welfare of her son, Venus (Aphrodite) sent Cupid (Eros) to Dido to make her fall in love with Aeneas. Juno, in turn, also decided to marry Aeneas to Dido and detain him forever in Carthage. She arranged so that when Aeneas and Dido were hunting together, a thunderstorm broke out, from which they took refuge in a cave, where they became lovers.

Aeneas was already going to stay in Carthage and marry Dido, but Jupiter sent Mercury (Hermes) to him with an order not to forget about his destiny and sail to Italy. Obeying the will of the gods, Aeneas left the hospitable Carthage.

Unable to bear the separation from her beloved, Dido committed suicide. Before she climbed the fire and plunged the sword of Aeneas into her chest, she predicted the enmity of Carthage with Rome.

Artificial leather for touch emulation 15.04.2024

In a modern technology world where distance is becoming increasingly commonplace, maintaining connection and a sense of closeness is important. Recent developments in artificial skin by German scientists from Saarland University represent a new era in virtual interactions. German researchers from Saarland University have developed ultra-thin films that can transmit the sensation of touch over a distance. This cutting-edge technology provides new opportunities for virtual communication, especially for those who find themselves far from their loved ones. The ultra-thin films developed by the researchers, just 50 micrometers thick, can be integrated into textiles and worn like a second skin. These films act as sensors that recognize tactile signals from mom or dad, and as actuators that transmit these movements to the baby. Parents' touch to the fabric activates sensors that react to pressure and deform the ultra-thin film. This ... >>

Petgugu Global cat litter 15.04.2024

Taking care of pets can often be a challenge, especially when it comes to keeping your home clean. A new interesting solution from the Petgugu Global startup has been presented, which will make life easier for cat owners and help them keep their home perfectly clean and tidy. Startup Petgugu Global has unveiled a unique cat toilet that can automatically flush feces, keeping your home clean and fresh. This innovative device is equipped with various smart sensors that monitor your pet's toilet activity and activate to automatically clean after use. The device connects to the sewer system and ensures efficient waste removal without the need for intervention from the owner. Additionally, the toilet has a large flushable storage capacity, making it ideal for multi-cat households. The Petgugu cat litter bowl is designed for use with water-soluble litters and offers a range of additional ... >>

The attractiveness of caring men 14.04.2024

The stereotype that women prefer "bad boys" has long been widespread. However, recent research conducted by British scientists from Monash University offers a new perspective on this issue. They looked at how women responded to men's emotional responsibility and willingness to help others. The study's findings could change our understanding of what makes men attractive to women. A study conducted by scientists from Monash University leads to new findings about men's attractiveness to women. In the experiment, women were shown photographs of men with brief stories about their behavior in various situations, including their reaction to an encounter with a homeless person. Some of the men ignored the homeless man, while others helped him, such as buying him food. A study found that men who showed empathy and kindness were more attractive to women compared to men who showed empathy and kindness. ... >>

Mass production of bioprocessors 28.02.2016

A bioprocessor is a SiP capable, if the device has the appropriate sensors, to provide measurements of various vital signs of the owner (ECG, GSR, body temperature, and so on).

The Korean giant has published an official press release on this development. The company reports that this very Bio-Processor, hiding behind the catalog number S3FBP5A, is already in production.

The new SiP includes an analog interface (AFE), a Cortex-M4 microcontroller, a power control integrated circuit (PMIC), a digital signal processor (DSP), and 512 kB eFlash memory. All this allows the solution to process signals from sensors without requiring external processing units for each of them. True, some sources for some reason claim that Bio-Processor is able to track the owner’s indicators mentioned above without sensors at all, but this, of course, is not true.

Thanks to the integration of multiple blocks, Samsung's development takes up four times less space than the now common combined solutions that can perform the same range of tasks.

You can also find out the exact list of SiP features from the press release. So, the bioprocessor is able to measure and record bioelectrical impedance, photoplethysmogram, electrocardiogram, skin temperature and galvanic skin reactions. In turn, this data allows you to calculate the mass fraction of fat in the body, determine the heart rate and indicate the level of stress.

In finished devices, the development of Samsung will appear in the first half of this year.
