TOI-700 c
Planet· orbits TOI-700
TOI-700 c — a sub-Neptune (2.6 Earth radii) on a 16-day orbit, larger and gassier than its rocky siblings. Its transit gives a real size; its mass is only size-estimated, so no density is quoted. Never imaged.

Composition
- Bulk composition
- A sub-Neptune (2.6 Earth radii), larger and probably volatile-rich; its size is measured, its mass only size-estimated, so no density is quoted. Never imaged.
- 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
- 2.65 S⊕ · 2.65× the sunlight Earth receives
- Computed from TOI-700's luminosity and the orbital distance (inverse-square; Earth's sunlight = 1).
- Equilibrium temperature
- 356 K (83 °C)
- Computed model value for its 16-day orbit — not measured.
Discovery & history
- Method
- Transit detection
- Name
- Designated 'c' under the IAU convention that letters a star's planets 'b', 'c', 'd'... in the order they are found (the star is the unwritten 'a'); no IAU proper name has been assigned.
Announced in 2020 with planets b and d as the middle world of the system.
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.
