An Asteroid with a Moon!

Apparently on Monday an asteroid passed very close to the Earth-Moon system, just over three times the Earth-Moon distance away. NASA’s Deep Space Network antenna array tracked it by radar.

There’s a video of this on the JPL site. The moon is clearly visible. Astounding stuff.

I found this via Astronomy Picture of the Day.

Don’t You Feel Small?

Earth and Moon from Cassini spacecraft

The above is a photo of the Earth and Moon as taken from the Cassini spacecraft in orbit around Saturn.

A slightly different view is given on yesterday’s Astronomy Picture of the Day.

The photo was taken on July 19th.

The JPL site (Jet Propulsion Laboratory) has more.
