Confirmed exoplanet · Database record + computed analysis
DH Tau b
A confirmed world orbiting DH Tau, 439.8 light-years away.
A gas giant
30.26 Earth radii, Jupiter-class (Jupiter is 11.2). At only 3496.0 Earth masses for that size, it must be substantially gas or volatile ices: puffy, not rocky.
Temperature and starlight
Its equilibrium temperature (the airless-world estimate) is about 1,927 °C. Hot enough to melt copper; any surface would glow.
Its sun
Its star is an orange K-type (4,371 K), M0.5: cooler and longer-lived than the Sun, a class some astronomers consider ideal for habitability.
How far is that, really?
At 440 light-years, tonight's light from this system left it around the year 1586. A Voyager-speed probe would need roughly 7,781,358 years to get there.
How we found it
It was directly imaged, one of the rare planets actually photographed as its own point of light, possible only for young, hot, wide-orbiting giants. The discovery was announced in 2004 from Subaru Telescope.
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.
