After passing perihelion — its closest approach to the Sun — 3I/ATLAS is showing signs of renewed activity.
Post-perihelion behavior is critical in understanding:
• Surface volatility
• Internal ice stability
• Structural integrity
• Outgassing evolution
• Rotational stress effects
Many objects become most unstable after perihelion, when internal heating continues even as they move away from the Sun.
New observations suggest:
• Increased brightness variability
• Fresh dust emission
• Possible fragmentation or vent activation
• Changes in coma structure
In this video, we break down:
Why post-perihelion phases can be more dramatic than approach
What renewed activity could mean for classification
Whether this is typical cometary behavior
And what astronomers will monitor next
Sometimes the most important changes happen after the closest pass.
