WASP-46 is a G-type main-sequence star about 1,210 light-years (370 parsecs) away.
[2] Despite its advanced age, the star is rotating rapidly, being spun up by the tides raised by a giant planet on a close orbit.
[6] The star displays an excess ultraviolet emission associated with starspot activity,[7] and is suspected to be surrounded by a dust and debris disk.
[2] The planet's equilibrium temperature is 1636±44 K.[4] The dayside temperature measured in 2014 is much higher at 2386 K, indicating a very poor heat redistribution across the planet.
[9] A re-measurement of the dayside planetary temperature in 2020 resulted in a lower value of 1870+130−120 K.[10] In 2017, a search for transit-timing variations of WASP-46b yielded zero results, thus ruling out existence of additional gas giants in the system.
