Kepler-90 c
Planet· orbits the Sun
Kepler-90 c — a second small, hot planet (1.19 R⊕) orbiting every 8.7 days. Size measured; mass size-estimated, so no density is quoted. Likely rocky. Never imaged.

Composition
- Bulk composition
- Slightly smaller than Earth (1.19 R⊕) and hot. Size measured; mass size-estimated, so no density is quoted. Presumed rocky.
- Surface appearance
- Appearance based on NASA/JPL-Caltech's artist's concept. No spacecraft has imaged this world, so its real appearance is unknown — The surface shown is an artistic representation, shown only in Vision mode; Realism shows a plain spectral colour.
Radiation & temperature
- Insolation
- 224 S⊕ · 224× the sunlight Earth receives
- Equilibrium temperature
- 987 K (714 °C)
Discovery & history
- Method
- Transit detection
- Name
- Designated 'c' 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 the seven planets confirmed around Kepler-90 in 2013.
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.
