Sun’s Shock Waves May Have Staggered Solar System’s Planet Formation
Our solar system’s planets may have formed at differing times, determined by shock waves flowing from the young sun, one astronomer suggests.

This theory posits that Earth is one of the youngest planets in the solar system, along with Mercury, Venus and Mars.
In a new paper, Tagir Abdylmyanov, an associate professor from Kazan State Power Engineering University in Russia, describes his idea and suggests it presents a possible new way of predicting where planets will form in young star systems.
“Studying the brightness of stars that are in the process of forming could give indications as to the intensity of stellar shock waves,” he said in a statement. “In this way we may be able to predict the location of planets around far-flung stars millions of years before they have formed.”
The theory has not been published in a peer-reviewed journal. Abdylmyanov presented his ideas this week at the European Planetary Science Congress in Madrid, Spain.
Eyeing the early solar system
Abdylmyanov adapted his own mathematical models by adding a solar system formation theory proposed by Japanese astrophysicists in 1985 in the book “Protostars and Planets II,” a University of Arizona publication that detailed planetary theory at the time.
In the decades-old paper, the Japanese scientists suggested that the solar system began with a solar nebula that gradually evolved to form clumps of dust that gelled to make protoplanets and then planets. Abdylmyanov takes that research a step further and says the planets formed at different times instead of at the same time.
