Giant gas planet in the livable region around our closest star-like system might be disappearing
In an exciting development for astronomy, researchers have potentially detected a Saturn-like gas giant planet named S1 orbiting the closest Sun-like star to Earth, Alpha Centauri A. The discovery, made using the James Webb Space Telescope's Mid-Infrared Instrument (MIRI), is yet to be confirmed.
The candidate planet was initially detected in 2024, but it was not seen in follow-up observations in early 2025, likely due to its orbit. S1's temporary disappearance during observations is thought to be a result of its orbit obscuring it.
If confirmed, astronomers may search for potential moons around the gas giant. S1's orbital dynamics remain to be fully understood and confirmed by further observations. Modeling suggests that S1 may have an eccentric orbit and is inclined relative to the Alpha Centauri A-B plane.
The object appears to have a similar mass to Saturn and could have a 2-3-year orbital period. It orbits roughly two astronomical units from its star, which is equivalent to twice the distance between Earth and the Sun.
The investigation of the candidate planet S1 involves researchers from the Space Telescope Science Institute, with Co-Lead Author Aniket Sanghi from Caltech contributing to determining its properties. If confirmed, this candidate would be the nearest world discovered orbiting a star like our Sun in its habitable zone.
The discovery of S1, if confirmed, makes the Alpha Centauri system more intriguing. If astronomers are successful in confirming its existence, they may have another chance to observe S1 around 2026-2027. MIRI, in combination with a coronagraph, was used to reveal the faint planetary signal near Alpha Centauri A.
It is important to note that S1, being a gas giant, is not habitable for life. However, the discovery of such a planet in the habitable zone of a star like our Sun adds to the intrigue and opens up new possibilities for future research.
Stay tuned for updates as astronomers continue to observe and study this potential Saturn-like planet orbiting Alpha Centauri A.
