ZZ Boötis is a star system in the constellation Boötes.

[10] Based on its parallax, measured by the Gaia spacecraft, it is about 350 light-years (110 parsecs) away.

[2] In 1950 Grigory Shajn determined that this star is a double-lined spectroscopic binary, with an approximate period of 4.96 days.

Sergei Gaposchkin found from an examination of photographic plates, in 1951, that it was an Algol-type eclipsing binary system.

[11] The primary and secondary eclipses are of equal depth, 0.65 magnitudes, meaning the brightness drops by nearly half.
