KELT-4Ab

KELT-4Ab is an extrasolar planet that orbits the star KELT-4A, in the star system KELT-4. The planet is approximately 760 ly away in the constellation of Leo. The planet was discovered by the Kilodegree Extremely Little Telescope (KELT).

Characteristics
The exoplanet was discovered by transit and is a Hot Jupiter planet orbiting a star in a triple star system, KELT-4. It is the fourth planet found in such a system. As KELT-4A is the brightest host (V~10) of a Hot Jupiter in a hierarchical triple stellar system found so far researchers expect it may be useful in learning more about inflated planets.

Star system
KELT-4 is a triple star system. KELT-4BC is a binary star system subcomponent of the triple, 328 ± away from KELT-4A and the projected separation between KELT-4B and KELT-4C is 10.30 ±.
