MP Muscae (PDS 66) is a star in the Musca constellation. A young star, it has not yet begun nuclear fusion at its core. MP Muscae is surrounded by a protoplanetary disk, and has one known exoplanet. Around 1.3 times the mass of the Sun and 97.9 parsecs (319 ly) away, it may be the nearest analog to the young Solar System.
