Using data from NASA's Transiting Exoplanet Survey Satellite (TESS) and the Next-Generation Transit Survey (NGTS), astronomers have discovered a transiting Saturn-like exoplanet circling NGTS-11 (also known as TOI-1847 and 2MASS J01340514-1425090), a mid K-type star located 624 light-years away in the constellation of Cetus. Named NGTS-11b (TOI-1847b), the planet has an equilibrium temperature of just 162 degrees Celsius (324 degrees Fahrenheit), making it one of the coolest known transiting gas giants.
NGTS-11b has a radius of 0.82 times that of Jupiter and a mass of 0.34 Jupiter masses.
The planet orbits its host star every 35 days at a distance 5 times closer than the Earth is to the Sun.
"NGTS-11b has a temperature of only 162 degrees Celsius -- cooler than Mercury and Venus," said lead author Dr. Samuel Gill, an astronomer in the Centre for Exoplanets and Habitability and the Department of Physics at the University of Warwick.
"Although this is still too hot to support life as we know it, it is closer to the Goldilocks zone than many previously discovered planets which typically have temperatures above 1,000 degrees Celsius (1,832 degrees Fahrenheit)."

...sorry...
Rilly, rilly kewl. Thanks.
My pleasure.

I used to work with a transiting gas giant. That jack-wagon could clear cubeville with a single crop-dusting pass.
