Beta Pictoris d
Planet· orbits the Sun
Beta Pictoris d — a giant planet of about 2–3 Jupiter masses on a wide ~91-year orbit (~26 AU), directly imaged in 2026 — the outermost known planet of the system. Young and self-luminous; its size and mass are model estimates, so no density is quoted.

Composition
- Bulk composition
- A young, self-luminous gas giant of ~2–3 Jupiter masses on a wide ~26 AU orbit — the outermost known planet of the system, imaged in 2026.
- 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 Vision mode; Realism shows a plain spectral colour.

Directly imaged in 2026, adding a third, outer world to the Beta Pictoris system that has been a touchstone of planet-formation studies for decades.
