Asteroid Initiative Workshop — Grand Challenge Panel Part 2

Any infor­ma­tion about
how far above the Earth­’s orbital plane was ISON when it passed,
how wide was it’s coma and how long was it’s tail at the time,
how long was ISON in the Earth­’s orbit
how far did it trav­el before it passed under the eclip­tic between the Earth and Venus,
what is the met­al­lur­gic and chem­i­cal com­po­si­tion of the debris Earth will encounter, and
what kind of chem­i­cal tran­si­tions might we expect to hap­pen in the Earth­’s atmos­phere (includ­ing with­in new­ly cre­at­ed noc­tilu­cent clouds) ?  Anyone?

Would be nice if you could post the links from these pan­els in the video descrip­tion NASA 🙂
