Confirmed exoplanet · Database record + computed analysis
HU Aqr AB b
A confirmed world orbiting HU Aqr, 626.9 light-years away.
A gas giant
12.80 Earth radii, Jupiter-class (Jupiter is 11.2).
The orbit
Its year takes 2,390 Earth days (6.5 Earth years).
Its sun
Its star is Sun-like (5,952 K; the Sun is 5,772 K). The system holds 2 stars, so its skies have more than one sun. It shares the system with 1 other known planet.
How far is that, really?
At 627 light-years, tonight's light from this system left it around the year 1399. A Voyager-speed probe would need roughly 11,090,890 years to get there.
How we found it
It was inferred from eclipse timing variations in its binary star system. The discovery was announced in 2011 from Yunnan Astronomical Observatory.
Everything above is computed from the archive’s measured values for this planet. Where a quantity is missing, the statement is omitted rather than guessed.
About this record
The measured values come from the NASA Exoplanet Archive, and any missing value has not been determined yet; the Atlas never fills gaps with guesses. More standout worlds: Proxima b, TRAPPIST-1e, K2-18 b, 55 Cancri e, and the detection methods that found them all.
