Situated 31 light-years away, Gliese 367b, colloquially known as Tahoe, orbits its sun in a mere 7.7 hours, captivating astronomers with its extraordinary composition — a planet predominantly composed of iron.

Initially discovered in 2021 by the TESS probe, recent studies by a team led by University of Turin scientists have unveiled more precise details about Tahoe's characteristics.

Initially thought to have a radius and mass of 72% and 55% of Earth's, respectively, the latest research reveals Tahoe's dimensions to be 70% of Earth's radius and 63% of Earth's mass.

Significantly denser than earlier estimates, Tahoe is now identified as twice as dense as Earth, earning it the moniker of a "ball of iron."

The mystery surrounding Tahoe's origin sparks various theories among researchers. One possibility suggests it might have started as a planet akin to Earth, but a catastrophic event stripped away its silicon-rich shell and mantle, exposing its dense iron core.

Alternatively, it could have formed in a protoplanetary disk with an unusually high iron content or originated as the exposed core of a gas giant, losing its atmosphere due to intense radiation after migrating close to its sun.

Tahoe belongs to the rare class of exoplanets known as "Super Mercury," sharing a composition similar to Mercury but exhibiting larger size and higher density. The research also unveiled two companion planets, Gliese 367c and Gliese 367d, both classified as "ultra-short-period planets" due to their proximity to the host star.

The discovery of these planets in Tahoe's system holds promise for understanding its enigmatic formation, shedding light on the intricate dynamics of planetary systems with "ultra-short-period planets."

Tess, while initially missing these companions, has now provided crucial insights into Tahoe's planetary family, deepening our understanding of the mysteries embedded in distant celestial realms.

Tahoe, the enigmatic iron-clad planet located 31 light-years away, continues to beckon scientists into the uncharted realms of planetary mysteries.

The recent revelations about Tahoe's density, twice that of Earth, add a layer of intrigue to its celestial narrative. Dubbed a "ball of iron," Tahoe challenges conventional understandings of planetary composition.

The quest to unravel Tahoe's origins sparks imaginative hypotheses among researchers.

Whether it underwent a cataclysmic event that stripped away its outer layers, transforming it into a dense iron entity, or it emerged from a protoplanetary disk with an exceptionally high iron concentration, each possibility underscores the dynamic and complex processes governing celestial bodies.

Tahoe's classification as a "Super Mercury" places it in a unique category, sharing similarities with our solar system's Mercury but showcasing distinct characteristics of size and density.

The discovery of Gliese 367c and Gliese 367d, Tahoe's planetary companions, further enriches our understanding of planetary systems with "ultra-short-period planets."

As Tahoe emerges as a beacon in the exploration of exoplanets, its mysterious nature fuels a deeper curiosity about the cosmos, inviting astronomers to delve into the intricacies of planetary formation and evolution, and offering a glimpse into the extraordinary diversity that exists beyond our celestial neighborhood.

The celestial ballet of Gliese 367b, alias Tahoe, unfolds as astronomers uncover its peculiarities. Beyond its dense iron constitution, Tahoe's origin story remains elusive, prompting speculation about catastrophic events or unique protoplanetary conditions shaping its distinctive features.

Tahoe's designation as a "Super Mercury" amplifies its cosmic allure, challenging preconceived notions of planetary classifications. The unveiling of companion planets, Gliese 367c and Gliese 367d, enhances Tahoe's cosmic narrative, offering a rare glimpse into the dynamics of planetary systems hosting "ultra-short-period planets."
