Pluto's baby twin moons, formerly known as S/2005 P 1 and S/2005 P 2, have been christened Nix and Hydra. The objects, discovered last year by the Hubble Space Telescope, received their names from the International Astronomical Union (IAU).

A formal announcement will be issued this Friday, 23 June.

"Names are very important," says space physicist Fran Bagenal of the University of Colorado. "They make it easier for people to relate to cosmic objects."

If galaxies were known as Tom, Dick, and Harry instead of some arcane catalog number, she says, more people would probably take up an interest in astronomy.

Yes, let's start naming all 100 billion galaxies, then all the stars in them,
then the planets circling them, then....

That'll draw in the masses.
