Scientists have discovered a planet with a density of marshmallows. The star has a diameter of 150,000 km, is slightly larger than Jupiter, and orbits its host once every 3.5 days. The research team calculated that TOI-3757 b has an average density of 0.27 grams per cubic meter, about a quarter of the density of water, and would float if placed in a giant bathtub of its size.
the Red dwarf stars The smallest and faintest types of stars that convert hydrogen into helium in their cores – at a constant rate. Although these stars are cooler than the Sun, they can be erupted by strong optical phenomena, making it rare for planets to form around them.
“It was thought that the formation of giant planets around red dwarf stars is difficult,” said Shubham Kanaudia, a researcher at the Carnegie Institution for Earth and Astronomy Laboratory at the Carnegie Institution for Science. They used Doppler surveys to examine the environment of red dwarf stars, and so far more distant giant planets have been discovered. “Until now, we have not had a sample large enough to detect nearby gas planets The researcher said does not depend on to me.
The planet’s atmosphere inflated, the causes are being investigated
TOI-3757 bt is still surrounded by some mysteries that scientists need to solve. The biggest mystery is how the planet could have ever formed, especially given its low density. One answer might be that the planet’s rocky core contains fewer heavy elements than other gas giants, which could delay gas buildup and reduce its density.
Another factor may be that the planet’s slightly elliptical orbit produces significant additional heating as it approaches its star, causing the planet’s atmosphere to swell.

The research could help astronomers understand what planets are, how they formed, and in the case of potentially habitable rocky worlds, whether they are able to. to preserve life.
