Astronomers have discovered a unique 'super-puff' planet that's as big as Jupiter, but 10 times lighter.

WASP-107b is very close to its star, WASP-107, with estimates suggesting the planet is over 16 times to its star than the Earth is to the Sun.

It lies around 212 light years away from Earth, in the Virgo constellation, and is very close to its star, WASP-107, with estimates suggesting the planet is over 16 times to its star than the Earth is to the Sun.

Estimates suggest that the planet is around the same size as Jupiter, but is around 10 times lighter.

This extremely low density indicates that the planet must have a solid core of no more than four times the mass of Earth, according to the researchers.

Estimates suggest the planet is over 16 times closer to its star, WASP-107, than the Earth is to the Sun.

Their results suggest that WASP-107b is around the same size as Jupiter, but is around 10 times lighter.

This extremely low density indicates that the planet must have a solid core of no more than four times the mass of Earth, according to the researchers.

Most gas giant planets, such as Jupiter and Saturn, have a solid core at least 10 times more massive than Earth.

Estimates suggest that the planet is around the same size as Jupiter, but is around 10 times lighter.

'For WASP-107b, the most plausible scenario is that the planet formed far away from the star, where the gas in the disc is cold enough that gas accretion can occur very quickly,' she said.

WASP-107c has a mass of about one-third of that of Jupiter, and is much further away from its central star than WASP-107b, taking three years to complete one orbit, as opposed to just 5.7 days
