We briefly outline the consequences that this first detection of an interstellar asteroid implies for the planet-forming process, and we assess the near-term prospects for detecting and observing (both remotely and in situ) future Solar System visitors of this type. Drawing on detailed heat-transfer calculations that take both `Oumuamua's unusual shape and its chaotic tumbling into account, we affirm that the lack of a detectable coma in deep images of the","authors_text":"Darryl Seligman, Gregory Laughlin","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.EP","submitted_at":"2018-03-19T16:31:59Z","title":"The Feasibility and Benefits of In Situ Exploration of `Oumuamua-like objects"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1803.07022","kind":"arxiv","version":2},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:54d2a6e4a9448d5d556b96366c208bb8aaea366f070628c61dff9564a8226030","target":"record","created_at":"2026-05-18T00:15:55Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"ebea6255ada19a10363b297ae017cccf69cac36393e4dbf99e13c2bcaf55bc67","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.EP","submitted_at":"2018-03-19T16:31:59Z","title_canon_sha256":"bdfad7f358839894f1b5e7193104b555f3aec260f2a37f24ba205a9612404c89"},"schema_version":"1.0","source":{"id":"1803.07022","kind":"arxiv","version":2}},"canonical_sha256":"c523b716ecda4048636250ad38684326026ffb5dca95ed883ef36df5b3831dc6","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"c523b716ecda4048636250ad38684326026ffb5dca95ed883ef36df5b3831dc6","first_computed_at":"2026-05-18T00:15:55.096146Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:15:55.096146Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"JWCO6U4m5bzlEGjKRIxd0/GFu+10kJ3Q9DwU1hiWkgeyFV79LcQWpI6i5Fy85gOiYOnFXbTx9Y8iYEia2M/ICg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:15:55.096892Z","signed_message":"canonical_sha256_bytes"},"source_id":"1803.07022","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:54d2a6e4a9448d5d556b96366c208bb8aaea366f070628c61dff9564a8226030","sha256:06d7457dbd7d5a7e3ffcf4f87e045a83e6e959b6fb21ffa05494a73854dc2466"],"state_sha256":"1e53668fa90e5be799c665db9454bddebcfb57d6faac3d1f8320b66df4ffc98c"}
