The star is older than the Sun and is strongly depleted in heavy elements compared to the Sun, having just 45% of the solar abundance. Despite its advanced age, the star is rotating rapidly, being spun up by the tides raised by a giant planet in a close orbit.

WASP-46 is a G-type main-sequence star about away. The star is older than the Sun and is strongly depleted in heavy elements compared to the Sun, having just 45% of the solar abundance. Despite its advanced age, the star is rotating rapidly, being spun up by the tides raised by a giant planet in a close orbit.
The star displays excess ultraviolet emission associated with starspot activity, and is suspected to be surrounded by a dust and debris disk.
