An unusual exoplanet in a triple-star system has been confirmed more than a decade after its first detection.
Unlike our solar system with one star, the Sun, many other systems have multiple stars.
Many observatories, on the ground and in space, together confirmed exoplanet K O I dash 5 A b, first detected by NASA's Kepler mission in 2009.

The planet's unusual orbit is not aligned with the horizontal plane of the stars.

Text, The planet's orbit raises questions about how the stars and planet formed from the same dusty gas cloud.
Astronomers say the case of K O I dash 5 A b shows how important mission collaboration is to understanding the physics of multiple-star systems.
