One year on GU Psc b lasts almost 163,000 Earth years.
The newly discovered exoplanet sits 2,000 times farther from its star than Earth sits from the Sun, making it the longest planetary orbit of any planet discovered.
The young, hot planet sits in the Pisces constellation, which is around 156 light-years from Earth, and its discovery has been described in Astrophysical Journal.
As Christopher Crockett explains in Science News, astronomers first spotted the planet as a speck of infrared light following its sun.

As Christopher Crockett explains in Science News, astronomers first spotted the planet as a speck of infrared light following its sun.
"The planet glows in infrared because it’s young — just 100 million years old — and still cooling,"Crockett writes.
It's estimated the planet would be around 800ºC and is nine to 13 times as massive as Jupiter.
In fact, there's even a chance that the "planet" may in fact turn out to be a very dim, lightweight star.
