The Non-Gravitational Acceleration of 3I/ATLAS is Not Directed Away from the Sun A new study on the small, icy body 3I/ATLAS has revealed that its non-gravitational acceleration is not directed away from the Sun as previously thought. The finding has significant implications for our understanding of the behavior of these small bodies in the outer reaches of our solar system. For decades, scientists have been studying the orbital motion of small bodies like 3I/ATLAS, which orbits the Sun at a distance of about 33 astronomical units (AU). One of the key factors affecting their motion is non-gravitational acceleration, which arises from the interaction between the small body and the solar wind, radiation pressure, and other external forces. Previous research had suggested that 3I/ATLAS's non-gravitational acceleration was directed away from the Sun, a phenomenon known as "solar radiation pressure." This would imply that the small body was being pushed away from the Sun by the intense energy output of our star. However, new data and analysis have challenged this assumption. A team of researchers has re-examined the orbital motion of 3I/ATLAS using advanced computational models and a more detailed understanding of the solar wind and radiation pressure. Their results show that the non-gravitational acceleration is actually directed towards the Sun, not away from it as previously thought. This finding has important implications for our understanding of the dynamics of small bodies in the outer reaches of the solar system. It suggests that these objects may be more susceptible to the influence of the solar wind and radiation pressure than previously believed, which could affect their orbital motion and potentially even their composition. The discovery also highlights the importance of refining our...#3i_atlas #solar_wind #radiation_pressure #astronomical_units #au #sun
