EZ Aquarii is a triple star system approximately from the Sun in the constellation Aquarius. It is also known as Luyten 789-6 and Gliese 866. All three components are M-type red dwarfs. The pair EZ Aquarii AC form a spectroscopic binary with a 3.8-day orbit and a 0.03 AU separation. This pair share an orbit with EZ Aquarii B that has an 823-day period. The A and B components of Luyten 789-6 together emit X-rays. The configuration of the inner binary pair may permit a circumbinary planet to orbit near their habitable zone. EZ Aquarii is approaching the Solar System and, in about 32,300 years, will be at its minimal distance of about from the Sun. The ChView simulation shows that currently its nearest neighbouring star is Lacaille 9352 at about from EZ Aquarii.
