You didn’t think a mini-moon (Temporarily-Captured Flyby, or TCF) would go by uncommented? I generally stay away from citing arXiv, since it’s basically uncontrolled. But the response time for Mini-Moon 2024 PT5 is too short for a refereed journal, so… Read More »Note, Pa-pre: Mini-moon 2024 PT5
Nothing new for anyone who already works in NEOs, but… here’s a nice overview paper. In the latest issue of Remote Sensing (vol. 16, issue 22, November #2): Espartero, F. Cubas, J. Nespral, D. et al. New Astronomical Observatory Design… Read More »Note, Paper: Get A Sense Of All Them

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

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
