Beta Pictoris d
Planet· orbits Beta Pictoris
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.

Science
Physical
- Mass
- 4.56 × 10²⁷ kg · 2.4 M♃ (763 M⊕)
- Radius
- Not measured
- Directly imaged, never transited: size and mass (~2–3 Jupiter) 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 Visual mode; Realism shows a plain spectral colour.
Radiation & temperature
- Insolation
- 0.0133 S⊕ · 1% of the sunlight Earth receives
- Computed from Beta Pictoris's luminosity and the orbital distance (inverse-square; Earth's sunlight = 1).
Discovery & history
- Method
- Directly imaged
- Name
- Designated 'd' under the IAU planet-lettering convention; no IAU proper name.
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.
Images
Directly imaged in 2026, but no openly-licensed image of Beta Pictoris d is available yet. See the system view for the debris disk and the earlier-imaged Beta Pictoris b.
