A faint and frigid little moon doesn’t have to go by “Neptune XIV” anymore.
Astronomers have given a name — “Hippocamp” — to the most recently discovered moon of Neptune, which also formerly went by S/2004 N1. They’ve figured out how big the satellite is as well, and teased out some interesting details about its past, a new study reports.
A team led by Mark Showalter, of the SETI (Search for Extraterrestrial Intelligence) Institute in Mountain View, California, announced the existence of S/2004 N1 in 2013. The scientists did so after analyzing photos taken by NASA’s Hubble Space Telescope between 2004 and 2009.
