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

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
