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)
WASP-12 b completes an orbit in little more than a day and is being strongly affected by its host star's gravity and radiation.
Transit photometry and spectroscopy
WASP-12 b is not resolved as a surface. Its listed properties come from changes in host-star light or motion; atmospheric claims, where attempted, depend on instrument sensitivity and retrieval models.
- What remains least constrained about WASP-12 b?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.
