APOD: Comet 21P Between Rosette and Cone... (2018 Oct 08)

Comet 21P Between Rosette and Cone Nebulas
Explanation: Small bits of this greenish-gray comet are expected to streak across Earth's atmosphere tonight. Specifically, debris from the
eroding nucleus of
Comet 21P / Giacobini-Zinner, pictured, causes the annual Draconids meteor shower, which peaks this evening.
Draconid meteors are easy to enjoy this year because meteor rates will likely peak soon after sunset with the
Moon's glare nearly absent. Patience may be needed, though, as last month's
passing of 21P near the Earth's orbit is
not expected to increase the Draconids' normal meteor rate this year of (only) a few meteors per hour. Then again, meteor rates are notoriously hard to predict, and
the Draconids were quite impressive in
1933, 1946, and
2011. Featured,
Comet 21P gracefully posed between the
Rosette (upper left) and
Cone (lower right) nebulas two weeks ago before
heading back out to near the orbit of
Jupiter, to return again in about
six and a half years.

green in a sea of
red, a sea of Cones and Roses!
It's pretty! But one color is missing from the APOD. To show you which one, I'm posting another picture of the Rosette and Cone nebulas. And in case you still don't get it, at right is a closeup of the Cone nebula and the Christmas Tree Cluster.

As helpfully pointed out by several emailers, the name of this comet includes "21P", not the number-reversed version that appears in the title. This has now been corrected on the main NASA APOD. Thank you to those emailers. I apologize for the cofnusion (sic). - RJN
