The EU-ESA Workshop on Size Determination of Potentially Hazardous Near-Earth Objects continues. For Tuesday, 11/12/24, we continued phase curves, but after that it was thermal infrared observations and polarimetry: https://indico.esa.int/event/530/contributions/ Absolute magnitudes and photometry from the MPC catalog Peter Vereš (Minor… Read More »Workshop: Size Determination of Potentially Hazardous NEOs pt.

Ongoing: the EU-ESA Workshop on Size Determination of Potentially Hazardous Near-Earth Objects (https://indico.esa.int/event/530). Step one in “Planetary Defense” is, of course, to spot the Potentially Hazardous Objects (PHOs). But step two is also important: gauge the size of the threat object.… Read More »Workshop: Size Determination of Potentially Hazardous NEOs
Let’s call these three MNRAS issues “October,” an arbitrary line: Volume 533, Issue 4, October Rodríguez Rodríguez, J. Díez Alonso, E. Iglesias Álvarez, S. et al. Light-curve analysis and shape models of NEAs 7335, 7822, 154244, and 159402 Pg 4160 … Read More »Note, Paper: MN-chanics
Yes, an incoming impactor was detected before impact. Object 2024 UQ was spotted (by the ATLAS telescope system) and reported back to the NEOCP (the Minor Planet Center‘s Confirmation Page). A trajectory solution determined that the object was likely to… Read More »Pre-detection of Impacting Meteor 2024 UQ
And now for a little change of venue. With the obvious exception of “mini-moons” (TCOs and TCFs) asteroid targets are in heliocentric orbits, and often at ranges measured in AUs. Round-trip light time is a few minutes, and it’s unrealistic… Read More »Note, Paper: A-Robot
It’s the last day of the American Astronomical Society‘s 56th annual DPS Meeting (Division for Planetary Sciences, #DPS2024). Just a little longer now. Here’s the schedule, per my highly biased blog and patch: submissions.mirasmart.com/DPS56/Itinerary/EventsAAG.aspx 405 – Small Bodies with JWST… Read More »AAS DPS meeting, four
