[Thomas the Tank Engine]

For only the second time, an exoplanet living with an expansive family of four stars has been revealed.

 

The exoplanet, which is a huge gaseous world 10 times the mass of Jupiter, was previously known to occupy a 3-star system, but a fourth star (a red dwarf) has now been found, revealing quadruple star systems possessing planets are more common than we thought.
