Confirmed exoplanet · Database record + computed analysis
DP Leo b
A confirmed world orbiting DP Leo, 997.0 light-years away.
A gas giant
12.70 Earth radii, Jupiter-class (Jupiter is 11.2). With 1995.9 Earth masses packed into that size, its density points to rock and iron rather than gas.
The orbit
Its year takes 10,220 Earth days (28.0 Earth years). The orbit is strongly stretched (eccentricity 0.39), so its distance from the star, and with it the climate, swings dramatically.
Temperature and starlight
Its equilibrium temperature (the airless-world estimate) is about -249 °C. Deep-freeze territory, colder than Antarctica's worst. It receives only 0.00 times Earth's starlight.
Its sun
Its star is hotter than the Sun (13,500 K), burning brighter and faster. The system holds 2 stars, so its skies have more than one sun.
How far is that, really?
At 997 light-years, tonight's light from this system left it around the year 1028. A Voyager-speed probe would need roughly 17,639,653 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 2009 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.
