Super Earth "that should not exist" revealed

(NLDO) - Super Earth WASP-132c, where 1 year is only 1 day on Earth, should not exist according to traditional cosmological models.

According to Sci-News, scientists have just discovered extremely strange details about the three-planet system surrounding the star WASP-132 located 403 light years from Earth.

Previous data has revealed that there are two planets and one possible planet around this orange star.

Now, a team led by Dr François Bouchy from the Observatory of Geneva (Switzerland) has carried out in-depth observations and analysis to determine the nature of the planets. They were surprised.

The most visible planet, WASP-132b, has a mass half that of Jupiter in the Solar System and orbits its parent star every 7.1 days.

It belongs to a class of planets called "hot Jupiters", a group of gas giants that are similar in nature to Jupiter, but orbit so close to their parent star that they are extremely hot.

Hot Jupiters discovered in other star systems have always been loners.

They initially form far from their parent star but gradually migrate closer. This migration destabilizes the orbits of other planets.

As a result, hot Jupiters either absorb their sibling planets or kick them out of the star system.

But for this star system, between the parent star and the hot Jupiter, a second planet named WASP-132c appeared unexpectedly.

Even more surprising, in-depth analysis shows that although its mass is six times that of Earth, its density is similar. Therefore, it is a type of planet known as a "super-Earth".

Of course, despite its Earth-like properties, it is not expected to support life. Orbiting so close to its parent star would turn the planet into a terrifying "fiery hell".

In addition, the study, recently published in the journal Astronomy & Astrophysics, also confirmed a third planet in the system, named WASP-132d, a giant icy planet that orbits its parent star every 5 years.

According to Dr Bouchy, this discovery requires the theory of hot Jupiter formation to be reconsidered, because it is clear that not all of them are cannibals - or knock out - their planetary siblings.

WASP-132b is an example of a more peaceful migration pattern that some fiery giants like it may have followed, albeit in the minority.
