    this is the image of the dwarf planet pluto.(too small -.-) The green circle in both snapshots marks the newly discovered moon, temporarily dubbed P4, found by Hubble in June.

    P4 is the smallest moon yet found around Pluto, with an estimated diameter of 8 to 21 miles (13 to 34 km). By comparison, Pluto's largest moon Charon is 648 miles (1,043 km) across. Nix and Hydra are roughly 20 to 70 miles (32 to 113 km) wide.

    The new moon lies between the orbits of Nix and Hydra, two satellites discovered by Hubble in 2005. It completes an orbit around Pluto roughly every 31 days.

    The tiny satellite was seen in a Hubble survey to search for rings around the frigid dwarf planet. The observations will help NASA's New Horizons mission, scheduled to fly through the Pluto system in 2015.

    so what is your Opinion on the discovery on Pluto's 4th moon? happy sad, surprised or annoyed?

    It offended me that another moon was discovered orbiting Pluto.

    JK

    No, it's pretty sweet. I wonder what it would be like to have found something like that.

    Why be sad? It's a breakthrough in astronomy!

    It lowered his self esteem. He's a little sensitive to space discoveries.

    You all skipped the same day in First Grade Astronomy, didn't you?
    Charon is the most well-known.
    Nix, Hydra, and S/2011 P1 are the others.
