7 Aquilae is a
apparent visual magnitude of 6.9. The star is moving closer to the Earth with a heliocentric radial velocity
of −21 km/s.
Houk and Swift (1999) find a
Sun's radius. The detection of an infrared excess suggests a debris disk with a mean temperature of 140 K is orbiting about 16.30 AU away from the host star.[5]
