Exoplanet Census
The exoplanet archive adds thirteen confirmed worlds
NASA's weekly update includes TOI-1355 b, an eccentric hot super-Jupiter whose changing geometry will end its observable transits around 2033.

The NASA Exoplanet Archive's November 5 update adds thirteen planets and new parameters for ten more. The highlighted system is TOI-1355 b, a massive planet on a roughly two-day, eccentric orbit around an early A-type star with a surface temperature near 8,400 degrees Celsius.
Orbital precession is expected to move TOI-1355 b out of the transiting geometry around 2033, after which its passages across the star will not be visible from Earth for hundreds of years. The planet itself is not disappearing; only the alignment that lets observers measure its transit is changing. Most of the discovery work was published earlier, while today's development is the official archive addition.
Why it matters
The weekly archive update turns individual papers into a maintained, queryable census. TOI-1355 b also shows why some valuable observing windows are temporary even when the planet is stable.
What the source establishes
Confirmed NASA Exoplanet Archive update dated November 5. The thirteen additions and ten parameter updates are official database changes; the highlighted planet's migration history remains an interpretation of its measured orbit.
