Confirmed exoplanet · Database record + computed analysis
LP 714-47 b
A confirmed world orbiting LP 714-47, 171.6 light-years away.
A Neptune-class world
4.25 Earth radii, in the ice-giant size range.
The orbit
Its year, one full orbit, takes just 4.1 Earth days. Orbiting this tightly around a cool star, it is very likely tidally locked: one hemisphere in permanent day, the other in permanent night.
Temperature and starlight
Its equilibrium temperature (the airless-world estimate) is about 450 °C. Hotter than Venus's surface. It receives 38.5 times the starlight Earth gets.
Its sun
Its star is an orange K-type (4,123 K), M1 V: cooler and longer-lived than the Sun, a class some astronomers consider ideal for habitability.
How far is that, really?
At 172 light-years, tonight's light from this system left it around the year 1854. A Voyager-speed probe would need roughly 3,036,234 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 2020 from Transiting Exoplanet Survey Satellite (TESS).
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.
