TOI-2322 c
TOI-2322 c is a super Earth exoplanet that orbits a K-type star. Its mass is 18.1 Earths, it takes 20.2 days to complete one orbit of its star, and is 0.1362 AU from its star. Its discovery was announced in 2025.
Discovered: 2025
🪐‘My main motivation is that I want to find out how life could have arisen at Earth.’
Planetary scientist at the UG Tim Lichtenberg recently found an unexpected atmosphere, while his colleague Quentin Changeat studies that of a rocky 'lava planet'.🔥

Astrum: *James Webb Just Saw Something Exciting on TRAPPIST-1e*
"This new discovery on TRAPPIST-1e could make it the most Earth-like planet ever discovered."

Astronomers found an #atmosphere where they least expected it—clinging to an #exoplanet that’s too small, too hot and too old to have air, at least in theory.
Observations of the blazing-hot lava #planet TOI-561 b suggest not only that it has a thick atmosphere but also that it may have had one for billions of years.
This is the strongest evidence yet for "air" around a hot rocky world that isn’t just a temporary veil of #hydrogen and #helium left over from planetary formation.

The age of exoplanets began in 1992, when astronomers detected a pair of planets orbiting a pulsar. Now, NASA has announced that there are 6,000 confirmed exoplanets. Read more from @ScienceAlert:

Once again, don’t trust the output of any #AI assistant without verification. This is not the HR 8799 exoplanet system, it’s the YSES 1 exoplanet system.
