A study finds reasons why our planet is so big and prevented from inflation

A study by astronomers from Rice University in Houston, Texas, revealed that long before the planets formed in the solar system, the sun had rings similar to those around Saturn, and may have stopped the growth of planet earth, so it became of this size and did not enlarge, and these rings were seen around a number of distant young stars similar to the Sun.

According to the British newspaper, “Daily Mail”, researcher Andre Isidoro said: “In the solar system, something happened that prevented the Earth from growing into a much larger type of terrestrial planet.”

Isidoro and colleagues used a supercomputer to simulate the formation of the solar system hundreds of times, to better understand how it appeared. Their model produced rings and reproduced many features of the solar system that many previous models missed, but it showed rings around the sun in the early universe.


A team of astronomers, astrophysicists and scientists participated in the study planetsDrawing on the latest research on new star systems, the model they created assumes that the early solar system had three high pressure bands within the disk.

“Because the particles are moving faster than the gas around them, they feel a headwind and drift very quickly toward the star,” said astronomer and study co-author Andrea Isela.

Isella added, astronomers have observed pressure bumps and protoplanetary disk rings using the Atacama Large Millimeter / Sub-array (Alma), a massive 66-dish radio telescope.

Isella explained: “The Alma Capable of taking very sharp images of young planetary systems that are still forming, we found that many protoplanetary disks in these systems feature rings.”
