- The Solar System occasionally receives interstellar visitors, objects not originating from our system.
- Three identified interstellar objects include ��Oumuamua (2017), Comet Borisov (2019), and 3I/ATLAS.
- 3I/ATLAS exhibits non-gravitational acceleration with a sideways component, suggesting an irregular surface.
- Hubble observations show multiple jet structures on 3I/ATLAS, aligning with its unusual acceleration.
- The JUICE mission unexpectedly observed 3I/ATLAS, providing rare spacecraft data on an interstellar comet.
- 3I/ATLAS's behavior is surprisingly similar to Solar System comets, hinting at universal planetary formation processes.
- Improved telescopes like the Vera Rubin Observatory may soon increase discoveries of interstellar objects.
- Interstellar comets offer samples of distant planetary systems, acting as chemical messages from other stars.
