The aim of this investigation is to locate the orbits of Venus and Earth in phase space, respectively to see how close their orbits are to chaotic motion which would lead to unstable orbits for the inner planets on much shorter time scales. Therefore we did numerical experiments in different dynamical models with different initial conditions -- on one hand the couple Venus-Earth was set clos","authors_text":"\\'Akos Bazs\\'o, Christoph Lhotka, Elke Pilat-Lohinger, Rudolf Dvorak, Veresa Eybl","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.EP","submitted_at":"2009-11-12T10:51:02Z","title":"An Overview of the 13:8 Mean Motion Resonance between Venus and Earth"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"0911.2357","kind":"arxiv","version":1},"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":"sha256:1a0de4f54829faab8af2f65a74b00ec74f45a215039ba75b0e26506db11a01f1","target":"record","created_at":"2026-05-18T02:10:48Z","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":"4333e9386ea42a75052110a98e9b04045c6dfa29297bcc05b00266f20481add0","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.EP","submitted_at":"2009-11-12T10:51:02Z","title_canon_sha256":"0a06d79ea4be2b435add0b7b9c9869906ab51067809ce309b3f5c2254426138c"},"schema_version":"1.0","source":{"id":"0911.2357","kind":"arxiv","version":1}},"canonical_sha256":"a6787ac814038685fda0c8d98f49e5411ef7cdf7fe489f650772b29cc6ee21f7","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a6787ac814038685fda0c8d98f49e5411ef7cdf7fe489f650772b29cc6ee21f7","first_computed_at":"2026-05-18T02:10:48.379809Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:10:48.379809Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"+ZaFT7FfTL2ALo2sEQdgOdNf5Io5xWsJJ+t7KyOL7+C5xQdXYKv4GgJ0bVqkbbJVX8VfYp41JC7F0rpY83XPBQ==","signature_status":"signed_v1","signed_at":"2026-05-18T02:10:48.380625Z","signed_message":"canonical_sha256_bytes"},"source_id":"0911.2357","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:1a0de4f54829faab8af2f65a74b00ec74f45a215039ba75b0e26506db11a01f1","sha256:4995e0371d7ad07ad9c43302cec1746dac4433af6e5bb028d278e0af0586539f"],"state_sha256":"71c443e3588984cf07258669f26534e602b2dd53c620b008ccfdce2e5502ca4a"}
