Scientists reveal Neptune's tiny new moon, Hippocamp

In a paper published in Nature Astronomy today, astronomers announced their first observations of a tiny moon discovered around Neptune in 2013. This brought Neptune's total moon count up to 14. Until earlier this month, the moon was designated S/2004 N1 — S for satellite, 2004 for the year it was first imaged, N for Neptune and 1 for the first satellite to be discovered around the planet in 2004. But now that astronomers have been able to work out its orbit, the International Astronomical Union has formally named it Hippocamp.
