(1) We find that comet 107P/WH was active in 1949, 1979, 1992, 2005, and2009. (2) Its age can be measured. We find T-AGE=4700 comet years, WB-AGE=7800cy. (3) This is a methuselah comet very near to its dormancy phase, beingtemporarily rejuvenated due to a diminution of its perihelion distance. (4) Wemeasured the diameter as Deffe=3.67\pm0.06 km, and the rotational period,Prot=6.093\pm0.002 h.
