Venus
A rocky world beneath a dense, heat-trapping atmosphere.
- classification
- Terrestrial planet
- system
- Solar System
Venus is close to Earth in size but radically different at the surface, where a dense carbon-dioxide atmosphere produces extreme pressure and temperature.

Only values with an established scientific consensus are listed. Where a quantity is uncertain or model-dependent, it is discussed in the sections below rather than stated as data.
Overview (starter entry, expanded review pending)
Venus is close to Earth in size but radically different at the surface, where a dense carbon-dioxide atmosphere produces extreme pressure and temperature.
Imaging, spectra and orbital dynamics
Venus's surface or atmosphere is constrained by telescopic and spacecraft imaging where available; spectra identify materials, while repeated position measurements establish its orbit and system context.
- What remains least constrained about Venus?Composition, internal structure, formation history or local environment can require different observations and may remain model-dependent.
Items above are unresolved. Hypotheses are labelled as such and are not presented as confirmed findings.
