Celestia files for Near Earth Asteroid 2015 TB145
Asteroid 2015 TB145 will come within 1.3 Earth Moon distances of Earth on October 31. Despite being somewhere between 280–620 meters in diameter, it will be visible in small amateur instruments at closest approach, although North America will have the best view. The asteroid is a target for mapping with radar.
For those of us not in North America (or who just want to play around with the asteroid orbit, or who want to argue with people who claim this asteroid will hit us (it won’t)) I’ve made Celestia files for 2015 TB145. As usual, copy the data here to a plain text file (2015TB145.ssc) and copy the file to the Celestia extras folder.

I’m sorry, Brother Astroblooger. If this asteroid is not scheduled to hit us, we BIN readers just aren’t interested. If you want to go back to your drawing board and say it is going to hit Manhatten, that would be a story worth reading. But you did the OPPOSITE, and you actually told the truth and didn’t try to scare anyone. As a long time BIN reader, I truly appreciate this. However, by the time the Lheaz twins put this article up, by then it will be a direct hit as those girls are TRULY SCARY!!!! Thank you for being one of the very few honest BIN reporters but you won’t go very far here as far as your clicks go.
God Bless, Brother Astroblogger!!!
