What to remember

On WASP-127b, a planet beyond the Solar System, a jetstream wind blows at 33,000 km/h, or 9,200 m/s. It is the fastest wind ever measured on a planet.

WASP-127b is a low-density planet of the sub-Saturn type. It orbits WASP-127, an old G5-type star around 9.7 billion years old, located 524 light-years from Earth in the constellation of Sextans. The star has a mass of 0.9 solar masses, a radius of 1.3 solar radii and a temperature of 5,842 kelvin.

The study of exoplanets is one of the most dynamic fields of science, and its extremes may shift as new discoveries are made.
