I don't think it's too similar, to be honest.

The main differences being:
 * The Moon Biome spawns underground vs. the Star Biome spawns up in the sky.
 * The monsters for the Moon Biome are based on lunar elements vs. the monsters for the Star Biome being based on solar elements.

This leads me to think that the two ideas are different enough to coexist.

If you disagree, I would suggest taking it up with the creator of the idea. Talk it out with them and figure it out.
