NASA probe snaps Pluto's smallest moons for the first time
Getting kicked out of the major planet club always seemed a bit unfair to Pluto, considering that it has four more moons than Earth. On the other hand, two of those, Styx and Kerberos, are so small that we only found out about them a few years ago. NASA's New Horizons probe has just taken its first snapshots of those new satellites, something of a miracle considering it was 55 million miles away and Styx is only 4 to 13 miles across. It required 10 second exposures from the probe's sensitive Long Range Reconnaissance Imager (LORRI) and copious image processing to reduce background glare, resulting in the animation above.
