While brand new discoveries are being made in space with the developing technology, a new announcement came from the scientists today. Scientists shared that in the research they published in the past weeks, the least dense exoplanet was discovered to date.
The new planet, named TOI-3757b, consists of gas and orbits a red dwarf star in the constellation Auriga, 580 light-years from Earth. The planet was discovered with the ‘Transiting Exoplanet Survet Satellite (TESS)’ telescope developed for NASA’s Explorer program.
It has hundreds of times less mass than Jupiter:

Data obtained by the telescope revealed that the exoplanet could be even larger than Jupiter. The density of the planet was measured by the gravitational force in the light reflected from its star. The mass of the planet, which is larger than Jupiter, was 85 times greater than the Earth. On the other hand, Jupiter has 318 times more mass than Earth.
The planet had a mass of only 0.27 grams per square centimeter, according to these data. Moreover, the planet is so light that it is not yet known how the planet could even form near its star. The planet completes each orbit around its star in just 3.43 days.
