The first name was already used for an asteroid, the Greek name Kerberos has been selected. It refers to the moon P4 discovery in 2011 by the Wide Field Camera 3 of the Hubble telescope. Scientists tried to discover rings around Pluto when they found the first natural satellite. The brightness thereof is 10% and that of an albedo Nyx between 0.04 and 0.35. Kerberos is between 14 and 40 kilometers in diameter and is the smallest moon of Pluto in 2011.

In terms of its characteristics, Styx has a brightness of 4% of that of Nix. Its shape is irregular and have a diameter between 10 and 25 km. Its albedo varies between 0.35 and 0.04.

The names of two new moons of Pluto are linked and it is for this reason that the IAU decided to reject the proposal of users who opted for Vulcan has no link with the underworld.
