HD 106515 A b
A confirmed world orbiting HD 106515 A, 111.2 light-years away.
A gas giant
12.10 Earth radii, Jupiter-class (Jupiter is 11.2). With 6007.0 Earth masses packed into that size, its density points to rock and iron rather than gas.
The orbit
Its year takes 3,626 Earth days (9.9 Earth years). The orbit is strongly stretched (eccentricity 0.57), 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 -157 °C. Deep-freeze territory, colder than Antarctica's worst. It receives only 0.03 times Earth's starlight.
Its sun
Its star is Sun-like (5,362 K, G5 V; the Sun is 5,772 K). The system holds 2 stars, so its skies have more than one sun.
How far is that, really?
At 111 light-years, tonight's light from this system left it around the year 1914. A Voyager-speed probe would need roughly 1,967,268 years to get there.
How we found it
It was found by the radial-velocity method: the planet's gravity swings its star in a small circle, and that wobble shows up as a rhythmic Doppler shift in the starlight. The wobble's size gives the planet's minimum mass. The discovery was announced in 2012 from La Silla 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.
