EPIC 248847494 b
A confirmed world orbiting EPIC 248847494, 1,800.0 light-years away.
A gas giant
12.44 Earth radii, Jupiter-class (Jupiter is 11.2). With 4131.8 Earth masses packed into that size, its density points to rock and iron rather than gas.
The orbit
Its year takes 3,650 Earth days (10.0 Earth years).
Temperature and starlight
Its equilibrium temperature (the airless-world estimate) is about -90 °C. It receives only 0.19 times Earth's starlight.
Its sun
Its star is an orange K-type (4,898 K): cooler and longer-lived than the Sun, a class some astronomers consider ideal for habitability.
How far is that, really?
At 1,800 light-years, tonight's light from this system left it around the year 225. A Voyager-speed probe would need roughly 31,846,867 years to get there.
How we found it
It was found by the transit method: the planet crosses its star's face on schedule, dimming it by a tiny, repeating fraction. The dip's depth gives the planet's size. The discovery was announced in 2018 from K2.
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.
