At a GlanceAI
Thermophysical modeling of asteroid (1862) Apollo to quantify its Yarkovsky drift and YORP spin-state changes.
SummaryAI
This study analyzes how heat absorption and re-radiation on asteroid (1862) Apollo drive subtle but measurable changes in its orbit (Yarkovsky effect) and rotation (YORP effect). By applying a thermophysical framework, it links Apollo’s surface/thermal properties to these non-gravitational forces. The work helps improve long-term trajectory and spin predictions for near-Earth asteroids, which matters for both impact-risk assessment and understanding asteroid surface evolution.
Method SnapshotAI
Thermophysical modeling is used to interpret and quantify the Yarkovsky and YORP effects for asteroid (1862) Apollo.
BackgroundAI
Basic familiarity with asteroid dynamics and thermal physics, especially the Yarkovsky and YORP effects.
