Composition
- Bulk composition
- A sub-Neptune (2.66 R⊕). Size measured; mass size-estimated, so no density is quoted.
- 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 Visual mode; Realism shows a plain spectral colour.
Radiation & temperature
- Insolation
- 10.1 S⊕ · 10.1× the sunlight Earth receives
- Computed from Kepler-90's luminosity and the orbital distance (inverse-square; Earth's sunlight = 1).
- Equilibrium temperature
- 450 K (177 °C)
- Computed model value — not measured.
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 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.
