Astronomers have encountered a curious anomaly in the vastness of space: the recent detection of an exoplanet located 1,232 light-years away that exhibits some rather peculiar characteristics.
Designated as WASP-193b, this giant exoplanet is not only about 50 percent larger than our own gas giant, Jupiter, but also astonishingly boasts a density so low, it can be likened to that of cotton candy. Indeed, its density is just over 1 percent of that of Earth, making it one of the most peculiar planets discovered to date.
Exoplanets with the properties similar to WASP-193b are quite unusual, yet they promise to provide critical insights into the mysteries of planetary evolution. A team of international astronomers, led by Khalid Barkaoui of the University of Liège in Belgium, has been deeply involved in studying this fascinating object.
“WASP-193b competes for the title of second least dense planet known, following Kepler-51d,” says Barkaoui. “Its astonishingly low density stands out among the more than five thousand exoplanets we’ve discovered so far, presenting a challenge to the conventional models of gas giants, even if we assume it lacks a solid core.”
Delving into the eccentricities of such celestial bodies helps us not only place our own Solar System in perspective but also peeks into the processes by which planetary systems take shape and change over time.
WASP-193b orbits a Sun-like star, WASP-193, which shares many characteristics with our Sun in both mass and temperature. However, this exoplanet displays a much closer orbit, circling its star every 6.25 days.
By studying the light alterations from the star as the exoplanet moves in its orbit, the researchers could deduce the planet’s radius and mass. The results revealed that it has around 1.46 times the radius of Jupiter but only a fraction of Jupiter’s mass, resulting in a density of just 0.059 grams per cubic centimeter — on par with cotton candy.
According to Julien de Wit, a planetary scientist at MIT, the exoplanet’s likeness to cotton candy is mainly due to its high atmospheric content of air, rendering it “super fluffy.”
Despite the rarity of planets like WASP-193b, those known bear similarities that could shed light on how such ‘puffy’ planets are formed, speculating that thermal expansion due to close proximity to their star plays a significant role.
Yet, with the age of the star estimated to be up to 6 billion years, several questions about the formation and maintenance of WASP-193b’s atmosphere remain unsolved. Barkaoui comments, “WASP-193b is a cosmic enigma that beckons for further observational and theoretical exploration.”
The forthcoming studies of the James Webb Space Telescope may soon unravel the mystery of this extraordinary exoplanet. A single transit observation could potentially provide the answers that scientists are seeking regarding the existence of such a unique planetary body.

FAQ:
What is the density of WASP-193b?
The density of WASP-193b is approximately 0.059 grams per cubic centimeter.
How does the density of WASP-193b compare to Earth and Jupiter?
WASP-193b is far less dense than both Earth and Jupiter. Earth has a density of approximately 5.51 grams per cubic centimeter, and Jupiter’s density is about 1.33 grams per cubic centimeter.
Why is WASP-193b’s low density so significant?
Its low density is unusual and challenges current models of gas giant formation and structure. WASP-193b’s characteristics defy the standard understanding of how such planets should behave.
Could the James Webb Space Telescope help solve the mystery of WASP-193b?
Yes, follow-up observations with the James Webb Space Telescope are expected to provide valuable data that could explain the unique properties of WASP-193b.
Conclusion:
The discovery of WASP-193b and its peculiar properties highlight the diversity and complexity of exoplanets in our universe. This ‘cotton candy’ exoplanet challenges current astrophysical models and promises to provide deeper insights into the formation and evolution of planetary systems. With sophisticated instruments like the James Webb Space Telescope, we are on the cusp of unraveling the secrets of this fluffy, enigmatic world, enhancing our comprehension of the cosmos.
