WASP-43b
WASP-43b is a transiting planet in orbit around the young, active, and low-mass star WASP-43 in the constellation Sextans. The planet is a hot Jupiter with a mass twice that of Jupiter, but with a roughly equal radius. WASP-43b was flagged as a candidate by the SuperWASP program, before they conducted follow-ups using instruments at La Silla Observatory in Chile, which confirmed its existence and provided orbital and physical characteristics. The planet's discovery was published on April 14, 2011.

At the time of its discovery, WASP-43b had an orbital period of approximately 0.8 days (19.2 hours), the second-shortest orbit ever detected, surpassed only by WASP-19b. In addition, at the time of discovery, WASP-43b was the most closely orbiting hot Jupiter known, a phenomenon that can most likely be explained by its host star's low mass.
