APOD: The Day After Mars (2014 Nov 01)

[Gaffert]

Is there room for a "moon unit" in astronomy for near misses like these? Say 1 moon unit equals 384,399 km (the semi-major axis of the Moon's orbit). I'm sure (near and dear Miss) Moon Unit Zappa wouldn't mind.

Perhaps a "Lunonomical Unit"?

Did you see this composite image which showed the coma and Mars together?

Given the immense size of the comet, I am surprised at how unimpressive the view of the comet is from the planet . Explanations of dust storms and impending sunrise taken into account, I still expected more from such a close proximity fly-by.

It's also worth noting that none of the instruments at Mars are intended to look at dim objects in the night sky.
