Like Saturn, the Sun had multiple rings. As a result, the mass of the Earth is many times less than it should be.

When the Sun was born 4.6 billion years ago, our star was surrounded by at least three layers, which later formed the structure of these rings. Satellite planets have become the origin of the world Asteroid belt Various space objects in the Solar System

A team of scientists at Rice University in the US published their latest study in the December 30, 2021 issue of the journal Nature Astronomy using computer models to find the answer to this question: Why are there no large planets like Earth in our solar system? Also known as Super Earth. These planets are common in the Milky Way galaxy, with up to 30% of its moons orbiting sun-like stars.

To this end, the research team created a model of the formation of the solar system. In the example of young stars born now. Most of them are planetary dust disks. The protoplanetary disk is closed, and if you look closely at the dust and gas around the rising star, you will find that there are many layers of rings.

The sharpest image of the star, HL Tauri, has a ring around it.

By entering data into a model program, researchers have discovered that there are eight planets in the Solar System and the asteroid belt.

Dr Andre Isidoro, an astronomer on the Rice University research team, said: “The young star’s ring gathers near dust and gas groups. A” pressure bump “is a bar of high pressure that prevents particles from entering.

Pressure bumpers on a stellar dust dish. This causes the ring to layer and accumulate different particles into larger clumps. It then becomes the planet’s seed or embryo, allowing the formation of stars and space objects in the Solar System (planetesimals).

The innermost ring, closest to the Sun, has the highest temperature. Mercury, Venus, Earth, Mars, and other asteroids or near the asteroid belt that gave birth to the fine sand particles from dust or particles of silicate minerals.

The main constituents of the three-layer ring that once existed in the Sun are the innermost layer (red) silicate minerals and the middle layer (white-blue) water molecules. The outermost layer (green) is carbon monoxide. The rectangular region is the location of the planets in the inner solar system.

Low temperature middle ring. It gave birth to the gaseous planets Jupiter, Saturn, Uranus and Neptune, as they were primarily composed of ice or ice. The outermost ring contains carbon monoxide particles of dry ice or snow. Asteroids and space objects formed in the Kuiper Belt.

When the research team changed the settings on the new computer model. In particular, the Sun’s central rings form more slowly. As a result, super-Earth planets formed in the Solar System. Despite their Earth-like conditions, these planets are two to three times larger and up to 10 times more massive.

Dr. Isidoro concludes that “if the center ring had formed a little slower, the particles around the Sun would have been covered by dust particles that could have penetrated deeper into the Solar System, making our planet a super-Earth larger than it is today.”
