V1400 Centauri
It is not visible to the naked eye: you need a telescope to see it. It is only 16 million years old, which is a very young star. It is a variable star. In 2007, it was thought J1407 was eclipsed and orbited by a gas giant or brown dwarf with a giant ring system. In 2021, it was discovered the parent star is strongly variable, with a 5.4-year long magnetic activity cycle. This means it might not have a planet. The variation might be caused by the star itself.
