AI Thread Summary
The discussion centers on the boundaries between constellations, highlighting inconsistencies and gaps in their definitions. Users seek a more comprehensive resource for constellation borders, with links to relevant databases provided. The IAU's official site is mentioned as a key reference, while a paper by Nancy Roman is noted for its insights on celestial positioning within constellations. The arbitrary nature of constellation definitions based on ancient observations is acknowledged. Overall, the conversation emphasizes the need for clearer and more comprehensive information on constellation boundaries.

Nancy Roman published a paper on figuring out which constellation any celestial position is in: see here.

Asteroid, Data - 1.2% risk of an impact on December 22, 2032. The estimated diameter is 55 m and an impact would likely release an energy of 8 megatons of TNT equivalent, although these numbers have a large uncertainty - it could also be 1 or 100 megatons. Currently the object has level 3 on the Torino scale, the second-highest ever (after Apophis) and only the third object to exceed level 1. Most likely it will miss, and if it hits then most likely it'll hit an ocean and be harmless, but...
