WASP-43b [SEP] constellation
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
the closest orbit yet found at the time of WASP-43b's discovery. WASP-43's unusually low mass accounts for WASP-43b's small orbit. Because planets with orbits around stars like WASP-43 are not usually observed, models either suggest that planets like WASP-43b are either uncommon or have short lifetimes caused by a decay in their orbits. WASP-43b has a density of 2.20 g/cm
