Astrolábos
Sign in to saveAlso known as WASP-43 b, WASP-43b, TOI-656.01, TIC 36734222b
WASP-43b, formally named Astrolábos, 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.

WASP-43b, formally named Astrolábos, 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.
WASP-43b has an orbital period of approximately 0.8 days (19.2 hours), which at the time of discovery was the third-shortest known, surpassed only by WASP-19b and WASP-47e. At the time of its discovery, the size of WASP-43b's orbit was the smallest known for a hot Jupiter, probably due to its host star's low mass.
