Shallow Sky Meets Deep Sky

Asteroid and Galaxy

Asteroid 7 Iris and the Sombrero Galaxy, M104
Sketch and Details by Eric Graff

After taking a look at Boattini’s Comet, I decided to chase down another bit of solar system debris, Asteroid 7 Iris, bearing down on the Sombrero Galaxy (M104) in Virgo; the asteroid was half a degree away from the galaxy and two days from closest approach on May 6, 2008. I had hoped to make additional observations on subsequent nights, but the weather has not been cooperative, so here is my lone observation of this event.
NELM ~6.4; Pickering ~5-6.

  1. Hi Eric,
    I am writing book ‘Asteroids and dwarf planets and how to observe them’. I would like to include your sketch to help illustrate the chapter on visual observing. Could I please have your permission to do so. My email address is
