Timhunter orbits the Sun in the inner main-belt at a distance of 1.8–2.9 AU once every 3 years and 7 months (1,310 days).
[10] In March 2009, a rotational lightcurve of Timhunter was obtained from photometric observations by astronomer Petr Pravec at the Ondřejov Observatory in the Czech Republic.
Lightcurve analysis gave a well-defined rotation period of 14.55 hours with a brightness variation of 0.29 magnitude (U=3).
[a] One month later, another lightcurve was obtained by French amateur astronomers David Romeuf, Maurice Audejean and René Roy, which gave an alternative period solution of 7.1074 hours with an amplitude of 0.32 magnitude (U=2-).
Together with David Crawford he co-founded the non-profit International Dark-Sky Association with the aim to preserve and protect Earth's night sky from light pollution.
