There was another planet in the solar system

There was another planet in the solar system.

There may have once been another planet in the solar system that was ejected from its orbit, but whose presence has contributed to current planetary orbits, the Daily Mail reported.

The planets were born of dust and gas and surrounded the young Sun. It is believed that the orbits of the gas giants were once quite close and in the form of circles, but gravitational interactions have changed them to their current form. According to scientists, this configuration is "extremely unusual", but the reasons are unknown.

US scientists have created thousands of models of how the orbits of the planets in the solar system have evolved over time and believe they have found the most likely explanation. According to them, Jupiter and Saturn have moved to their "eccentric" oval orbits earlier than previously thought.

According to astronomers, the orbits of ice giants such as Uranus and Neptune were affected by the gravitational pull of a mysterious planet that is now missing and which they believe was an ice giant between Saturn and Uranus.

"We already know that there are thousands of planetary systems in our galaxy alone", said Matt Clement of the Carnegie Institution of Science in Washington, D.C., who led the study. "But it turns out that the arrangement of the planets in our solar system is quite unusual, so we used models to recreate the formation processes," he explained. "It's like trying to figure out what happened during a catastrophe - how much the cars were moving fast, in what directions", he added.

Scientists believed that at the dawn of its existence, Jupiter made three full orbits around the Sun during the time that Saturn made two full orbits. Analyzes by Clement's team have shown that this hypothesis does not explain the current configuration of the gas giants.

According to their model, Jupiter most likely made two revolutions around the Sun during the time that Saturn made one revolution. It has also been found that the orbits of Uranus and Neptune are influenced by many external factors. Among them are the gravitational influence of the Kuiper belt, as well as the impact of another ice giant that has been ejected from its orbit. The team believes that their model can be used to study the creation of planets and planetary systems that could have life.
