An impossible Jupiter-sized gas giant, TOI-5205b, the first exoplanet of its kind with an atmosphere containing far fewer heavy elements than similarly sized objects, as well as its own host red dwarf star - TOI-5205, discovered in data from NASA’s alien planet-hunting Transiting Exoplanet Survey Satellite (TESS).

Kanodia described TOI-5205b’s orbit of its host stars as a “pea going around a lemon” as opposed to Jupiter’s orbit of the Sun, which is like a “pea going around a grapefruit.”

Carnegie's Shubham Kanodia quoted in 2023:

TOI-5205b’s existence stretches what we know about the disks in which these planets are born. In the beginning, if there isn’t enough rocky material in the disk to form the initial core, then one cannot form a gas giant planet.

And at the end, if the disk evaporates away before the massive core is formed, then one cannot form a gas giant planet. And yet TOI-5205b formed despite these guardrails. Based on our nominal current understanding of planet formation, TOI-5205b should not exist; it is a “forbidden” planet.

Exciting to see Artemis II rocketing to the moon! It’s a long road from the moon to humans visiting exoplanets, and this is 35th in my “Exoplanet” series which explores facets of planets identified outside the solar system.

"
Seltener Nachweis zweier Protoplaneten
"
".. zwei Protoplaneten im jungen Sternsystem WISPIT 2 nachgewiesen – Planeten, die sich im Prozess ihrer Entstehung befinden. Die Entdeckung zweier Planeten-Embryos um einen Stern gelang unter mehr als 6000 Exoplaneten bisher erst in einem weiteren System: PDS-70."

🪐🔭 Proxima b is the closest Earth-like #planet to our #solarsystem and sits in the habitable zone where liquid water could potentially exist.

Future missions like Breakthrough Starshot aim to send tiny probes to study this neighboring #exoplanet in the coming decades.
