Kepler-11 f
Planet· orbits the Sun
Kepler-11 f — a low-mass sub-Neptune (2.49 R⊕) on a 47-day orbit. Its measured mass (~2 M⊕) gives a low density, another gas-rich world. Never imaged.

Composition
- Cloud appearance
- Appearance based on NASA/JPL-Caltech's artist's concept. No spacecraft has imaged this world, so its real appearance is unknown — The banded clouds shown are a representation of its class, shown only in Vision mode; Realism shows a plain spectral colour.
Radiation & temperature
- Insolation
- 16.8 S⊕ · 16.8× the sunlight Earth receives
Discovery & history
- Method
- Transit detection
- Name
- Designated 'f' under the IAU convention that letters a star's planets 'b', 'c', 'd'... in the order found (the star is the unwritten 'a'); no IAU proper name has been assigned.
One of six planets announced around Kepler-11 in 2011.
Images
No telescope has imaged this world — it is known only from the tiny dip it makes crossing its star. Only its host system has been pictured (see the system view); its true surface appearance is unknown.
