Electra /əˈlɛktrə/,[11] designated 17 Tauri, is a blue-white giant star in the constellation of Taurus located approximately 400 light years away.

The rapid rotation extends the life span of the star by increasing the core density and reducing the radiation output.

[7] Changes in the radial velocity measurements indicate that this star may have a companion, which would make Electra a spectroscopic binary.

Low amplitude variability of the brightness of Electra was detected by Kepler/K2, and Fourier analysis of the star's light curve shows several periods of oscillation, the strongest being 1.107 and 1.165 days.

This emission is probably from a gaseous disk created by radiation-driven mass loss and rapid rotation of the star.

These disks are created by an ejection of material roughly every ten years, which then settles into the equatorial plane about the star.
