35 Aquilae (abbreviated 35 Aql) is a

mas that is caused by the Earth's orbit around the Sun. This yields a distance estimate of 200 light-years (61 parsecs), give or take a 4 light-year margin of error. At this distance, the visual magnitude is diminished by 0.26 from extinction caused by interstellar gas and dust.[7]

The

projected rotational velocity of 110 km/s.[8]

In 1994 it was discovered that 35 Aquilae is a variable star with a pulsation period of just 30 minutes.[11] It was determined to be a Delta Scuti variable, which is a type of star found on the instability strip that undergoes short period pulsations.[4] Observation with the Spitzer Space Telescope shows that 35 Aquilae is radiating an excess level of infrared radiation for a star of its type. This excess may be explained by the heating of nearby interstellar dust belonging to a diffuse cloud of material that the star is passing through. This interaction may also explain the Lambda Boötis categorization for this star.[6]
