I would've guessed it was a reference to Eurydike (or Eurydice) the nymph, bride of Orpheus. Much more likely to be a mythology buff, or there's a couple plays/operas about Eurydike. I doubt that anyone would've picked an asteroid unless they discovered it for their name and considering the spelling I'd guess it's a fan of mythology as opposed to the operas.
I'll stick with astrology related. Here's a copy of a message I got from PS support once when I asked about the names on the site:
"Our freeroll tournaments are named after famous astronomers, to fit
with the theme of our site,
pokerstars.
Some of the astronomers for whom our freerolls are named are:
Stephen Hawking (work on black holes and the origin of space)
Nicolas Copernicus (discovered the earth revolves around the sun)
Sir Edmund Halley (of the famous comet)
Galileo Galilee (inventor of the telescope)
Edwin Powell Hubble (discovered the big bang theory)
Johannes Kepler (discovered of the 3 laws of planetary motion)
Giovanni Cassini (first to prove Earth was not a perfect sphere)
Sir Arthur Eddington (used solar eclipses to prove Einstein correct)
Carl Sagan (host of TV's 'Cosmos'; leader of Voyager probes)"
