172425 Taliajacobi           Discovered 2003 July 25 by D. Polishook at the Wise Observatory.
Talia Jacobi (b. 1977), of Ramot Meir, Israel, is a medical student, nature guide and fan of astronomy. This hobby drove her to observe the 2004 Perseid meteor shower, where she met the discoverer, and the two fell in love. They were married in Aug. 2008.
