7816 Hanoi

[2][7] Hanoi orbits the Sun in the inner main-belt at a distance of 1.6–3.0 AU once every 3 years and 6 months (1,287 days).

[7] In November 2011, a rotational lightcurve of Hanoi was obtained from photometric observations made American astronomer by Brian Warner at his Palmer Divide Observatory in Colorado.

[5] Ten years later, remeasurements of the original images rendered a slightly refined period of 5.17±0.01 and an amplitude of 0.77 (U=3-).

[3] This minor planet was named after the city of Hanoi, capital of Vietnam, which the discoverer visited in 1997.

The installed instrumentation was funded by the Japanese Sumitomo Foundation, with the intention to foster Vietnamese astronomical research.
