Styx from New Horizons

Styx from New Horizons
Styx from New Horizons Styx is Pluto's innermost small moon, and one of the last discovered (along with Kerberos). New Horizons took this photo from a distance of 631,000 kilometers, 12.5 hours out from Pluto closest approach. The image does not reveal any details but shows that Styx is very small indeed: in this image it appears about 5 by 7 kilometers in size. NASA / JHUAPL / SwRI
