We report on the observation and measurement of astrometry, photometry, morphology, and activityof the interstellar object 3I/ATLAS, also designated C/2025 N1 (ATLAS) with the NSF-…
Systematic and Statistical Uncertainties in the Non-Gravitational Acceleration of 3I/ATLAS
F. Spada, M. Królikowska, M. Królikowska +1
We present a detailed analysis of the trajectory of interstellar comet 3I/ATLAS, with emphasis on the determination of its non-gravitational acceleration (NGA) parameters and their…
