An Entity of Type : owl:Thing, within Data Space : 134.155.108.49:8890 associated with source dataset(s)

One of the two youngest stars (about a million years old) detected with evidence for a planet-forming circumstellar disk. Has an outer dust disk (which would envelop the Solar System) and a thin inner dust disk (which would fit inside Mercury's orbit). The inner disk is somewhat lopsided. Planet b was later detected, the youngest and first direct photograph of a protoplanet. It is a giant planet orbiting at Uranus-like distances and appears as a blue dot. It is about 1,000C and surrounded by a red structure about 500C, which could be material colliding into the protoplanet or being ejected from it. Its mass, and planetary status, still needs to be determined.
