This planet is still an unconfirmed candidate.

About 450 light-years, toward Centaurus

J1407 is a young star about 450 light-years away, toward the constellation Centaurus. In 2007, over 56 days, it dimmed and brightened again and again. It looked as if something wearing giant rings had passed in front of it.

Rings about 200 times Saturn’s

Researchers calculated that the thing crossing the star had more than 30 rings. The rings are about 180 million km across, wider than the distance from Earth to the Sun. The researchers said they are about 200 times bigger than Saturn’s rings. Moons might be forming in the gaps between them.

Why?The star is only about 16 million years old, which is very young. So these rings may not be old like Saturn’s, but a dusty disk where moons are still being made.

Learn moreNothing like it has been seen again since. So J1407b is still an unconfirmed candidate. It might not orbit the star at all, but be a lone object that happened to drift in front of it.
