35 Aquarii, also known by its Flamsteed designation, is a single star located approximately 2,200 light years away from the Sun in the zodiac constellation of Aquarius. It is visible to the naked eye as a faint, blue-white star with an apparent visual magnitude of 5.80. This object is moving closer to Earth with a heliocentric radial velocity of −7 km/s, and is suspected to be a runaway star, potentially ejected from an open cluster due to a binary–binary interaction. This star is a blue giant with a stellar classification of B2 III, indicating that it is a massive star that has evolved off the main sequence. With an age of around 22.5 million years, it has a relatively low projected rotational velocity of 10 km/s. The star has a mass of 10 times the mass of the Sun and is radiating 1,622 times the Sun's luminosity from its photosphere at an effective temperature of 17,400 K.
