Kepler-11 e
Planet· orbits the Sun
Kepler-11 e — the largest of the six (4.19 R⊕), on a 32-day orbit. Its measured mass (~8 M⊕) gives an extremely low density — one of the puffiest planets known, mostly a deep hydrogen-helium envelope. 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
- 27.6 S⊕ · 27.6× the sunlight Earth receives
Discovery & history
- Method
- Transit detection
- Name
- Designated 'e' 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 — the largest and puffiest.
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.
