Astronomers have discovered more than 5,000 exoplanets in the past 30 years, a diverse collection of planets located far beyond our solar system. And the most recent discovery could be as young as a child.

A newly published study in the journal The Astrophysical Journal Letters claims to have found one of the youngest planets ever discovered, and possibly the youngest.
According to a release issued by the National Radio Astronomy Observatory, this extremely young – in terms of the universe – orb, located 395 light-years from Earth in the constellation Ophiuchus, is still putting its gas and dust together.

A circumplanetary disk is a name for a phenomenon that contains a collection of gas, dust, and debris around newborn planets. These disks produce moons and other rocky satellites and regulate the development of young, massive planets.

The origin of our own solar system, as well as that of Jupiter’s Galilean moons, which researchers believe formed in a circumplanetary disk of Jupiter some 4.5 billion years ago, may be better understood by looking at these disks in their early phases, the argumentative scientists .

“It is like looking at our own past,” Myriam Benisty, an astronomer at the Institute of Planetology and Astrophysics of Grenoble in France and a co-author of the study, told the New York Times.

According to the study, further telescopic observations will be necessary to confirm the planet’s existence because it is allegedly hidden by the very substance that is creating it. Scientists can use it to learn more about how planets are created, if it’s not merely rocky debris that looks like a planet.

Long-held theories of planet formation have been challenged or proven false by the flood of recently discovered exoplanets. However, the fact that this young planet is securely embedded in a disk of primordial matter around its star supports the theory that most planets spend a significant amount of time in this type of nursery as they develop.

The researchers targeted the Atacama Large Millimeter/submillimeter Array (ALMA) at AS 209, a star that is just a little bit heavier than the sun, for the study. It is only 1.5 million years old and has just lately begun to burn hydrogen. It was discovered that AS 209’s circumstellar disk had many gaps.

Additionally, ALMA discovered the radio-wave of planet-forming a tempest in one of these gaps, which was likely to gas encasing globe that was still a signature Jupiter-like construction.

According to the research, it will take some time to determine the planet’s exact age, although it is most likely quite young, like its star. However, its youth is not the only factor attracting astronomers’ attention, as it is also strangely far from its star.

For instance, the distance between the Sun and Neptune, the solar system’s furthest planet, is approximately 4.5 billion km (2.8 billion miles). However, nearly 30 billion km (19 billion miles) separate this exoplanet from its own star.

Uncertainty surrounds the size of the debris disk that created Earth and the other planets. And there is a scientific opinion that Neptune’s position as the outermost planet may be explained by the fact that the disc was only marginally larger than Neptune’s orbit. However, the researchers suggest it is possible that our planet-forming material hub was more like AS 209’s.

The James Webb Space Telescope will measure the planet’s mass and analyze its atmosphere in the near future.
