description KELT-11b Overview
A highly inflated hot Saturn orbiting a subgiant star with one of the lowest densities among known exoplanets, making it a frequently cited benchmark for atmospheric modeling.
help KELT-11b FAQ
Why is KELT-11b called a hot Saturn?
KELT-11b is a low-mass, Saturn-like gas giant with an unusually expanded atmosphere. It orbits the subgiant star KELT-11 closely enough to be strongly heated.
Why is KELT-11b useful for atmospheric modeling?
KELT-11b is highly inflated and has one of the lowest densities among known exoplanets. Its unusual size-to-mass combination gives astronomers a useful benchmark for testing atmospheric models.
What kind of star does KELT-11b orbit?
KELT-11b orbits KELT-11, a subgiant star rather than a normal main-sequence Sun-like star. That host-star context is an important part of why the planet is studied.
Could KELT-11b be habitable?
No. KELT-11b is an inflated hot gas giant, not a rocky planet with a known solid surface, and its close orbit around KELT-11 creates a strongly heated environment.
