Unknown

AI-narrated summarySnapshot 7f3a · 2026-09-28
Unknown is a 0-m Sq-type near-Earth asteroid discovered 19 June 2004 by R. A. Tucker, D. J. Tholen and F. Bernardi at Kitt Peak. Its 13 April 2029 Earth flyby will pass within 38 012 km of the geocenter — closer than geosynchronous orbit and visible to the naked eye from EMEA . Goldstone observations in 2021 cleared all impact possibilities through 2100.

What MCPOrbital will not do

Explicit non-promises

Saying no to these protects the brand, the safety posture, and your budget. MCPOrbital operates in research, simulation, decision-support, and sandbox modes only.

  • Send a burn command to a real asset
    Live commanding is outside the safety policy. Route through your licensed ops chain.
  • Replace STK / GMAT for flight-grade analysis
    Sandbox sims are first-pass trade studies. High-fidelity stays in licensed tools.
  • Write your dissertation chapter
    We accelerate research; we don’t replace authorship. Briefs are drafts, not submissions.
  • Peer-review a paper
    We cross-check claims against current data. Peer review is human.
