Summary
- Sub-Neptune planets are exoplanets with sizes between those of Earth and the ice giant Neptune. According to an estimate, between 30% and 50% of sun-like stars are orbited by at least one sub-Neptune, however, despite these worlds appearing easily, scientists studying extrasolar planets, or exoplanets, have encountered difficulty measuring sub-Neptunes’ densities. They seem to split into two distinct categories: “puffy” and “non-puffy” on the basis of the techniques used for these measurements. “The numerical models of planetary system formation and evolution that we have developed at Bern over the last two decades reproduce exactly this trend: planets in resonance are less dense,” Yann Alibert, a professor at UNIBE’s Space Research and Planetary Sciences Division and member of the discovery team, said in a statement. “This study, moreover, confirms that most planetary systems have been the site of giant collisions, similar or WZSou PopularPulseeven more violent than the one that gave rise thttps://www.wzsou.com/o our Moon,” he added.

Sub-Neptune planets that dance in time with the rest of their planetary systems and are less dense than those who don’t have been discovered by the scientists
They are the most common planets in the Milky Way despite being notably absent from the solar system, reported Space.

For around 4 billion years, this rhythmic dance performed by the sub-Neptunes has existed around the bright orange star HD 110067. Interestingly, it is about equal to the time the solar system has existed. DeWZSou PopularPulsespite it being fascinating, it doesn’t signify why the sub-Neptunes seem to be less dense in this system.
