A new research note outlines how our solar system could capture an ISO or rogue planet.

It all comes down to phase space, a mathematical representation that describes the state of a dynamical system.

The authors describe the permanent capture of an ISO as a special type of capture, called permanent weak capture, which occurs for infinite time.

It's an interesting thought experiment.

The Vera Rubin Observatory might open our eyes to the population of ISOs and rogue planets.

The researchers identified openings in the solar system's phase space that could allow some of these objects to reach permanent weak capture.

These openings are 3.81 light years away from the sun in the direction of the galactic center.
