Nomadic planets flood the Milky Way

Our galaxy may contain more than 100,000 planets that move freely, not belonging to any solar system.

That is the conclusion drawn from the study of 'nomadic' planets conducted by the Stanford University team (USA), published on the Monthly Notices of the Royal Astronomical Society.

These planets have been discovered when their gravity temporarily twists the light of the sun they pass through, or the effect of a micro-lens prism due to gravity.

To calculate, astrophysicist Louis Strigari and colleagues analyzed the gravitational attraction of the Milky Way, the number of matter it contains, as well as the size of these materials.

One of the most interesting conclusions is that there is not enough solar system in the Milky Way for wandering planets, which means that not all nomadic guys will be kicked out of their homes before starting. wandering life.

The study raises new questions about how planets form, and whether there are differences in the process of creating planet-sized objects.

Experts also wondered if in the case of nomadic planets large enough to contain a thick atmosphere, they could also attract enough heat to allow life to exist as bacteria, according to the analysis of Mr. Strigari.
