A team of three astronomers from the University of Arizona have discovered a planet with three suns.
The planet is located about 320 light years from Earth and is 16-million years old.
The planet is four times larger than Jupiter and is being called Planet "HD 131399AB."
For about a quarter of its orbit, the planet is in constant daylight. As one sun sets, the other two rise.
A UofA led team used a telescope in Chile to spot the new planet.
