The Gaia mission has allowed researchers to understand the motions of stars like never before, even revealing possible interactions between our solar system and nearby stars. Planetary Science Institu...

The outer regions of AGN disks have temperatures similar to those of circumstellar disks, permitting dust condensation. Therefore, planet formation and growth could be active in these dust tori throug...

Simulations show that the stars’ tug could send Mercury, Venus or Mars crashing into Earth — or let Jupiter eject our world from the solar system.

Giant planets on wide, eccentric orbits—like the putative Planet Nine—may form from dynamical planetary instabilities when stars are embedded in their natal stellar clusters. Simulations suggest a 1–5% chance of such planets forming in exoplanetary systems and up to 40% in the Solar System.
