Avi Loeb: 3i Atlas, Jupiter Flyby, and Interstellar Object Anomalies

🚀 3i Atlas's Jupiter Encounter

• 🎯 The interstellar object 3i Atlas is projected to make an extraordinarily close flyby of Jupiter on March 16, 2026.
• 💡 Its trajectory places it precisely at Jupiter's Hill radius, the distance where Jupiter's gravity overcomes the Sun's, allowing objects to remain gravitationally bound.
• 🧩 This exact alignment, to within four significant digits, has a 1 in 26,000 chance of being a natural coincidence.

⚙️ Non-Gravitational Acceleration & Trajectory

• ⚡️ Observations revealed non-gravitational acceleration for 3i Atlas when it was closest to the Sun, causing it to deviate from its original path.
• 🧠 This deviation allowed it to achieve the precise trajectory needed to reach Jupiter's Hill radius, suggesting potential engine adjustments for a gravitational assist.
• 🛰️ The purpose could be to deploy devices (like probes or communication devices) near Jupiter, possibly at its Lagrange points, or to collect pre-placed items.

🔭 Monitoring with Juno & Upcoming Data

• 🛰️ The Juno spacecraft, currently orbiting Jupiter, can monitor 3i Atlas for any unusual activity, deployed satellites, or radio signals.
• 📢 Representative Anna Paulina Luna has encouraged NASA to use Juno to observe 3i Atlas, following Professor Loeb's discussions.
• 📈 A flood of new data is expected from hundreds of observatories globally between November 27th and January 27th, as 3i Atlas approaches Earth.

🔬 Analyzing Jets for Origin

• 🔍 Amateur astronomer images show multiple jets emanating from 3i Atlas, with up to seven observed in early images.
• 🧪 Measuring the speed of gas in these jets is crucial to determine their origin: natural sublimation of ice (max 400 m/s) or technological thrusters (kilometers to tens of kilometers per second).
• ✅ This analysis will help distinguish if 3i Atlas is a natural object or of artificial origin.

⚖️ The Loeb Scale & Future Insights

• 📊 Professor Loeb uses a "Loeb scale" (0-10) to assess the likelihood of an interstellar object being technological, with 0 being natural and 10 being a potential threat.
• 🤔 He currently rates 3i Atlas at a "four" but is awaiting the upcoming data before revising his assessment.
• ⏳ New data by the holidays should provide clearer insights into the true nature of 3i Atlas.
