On this day in 1945 - February 23rd - Ukranian astronomer Svetlana Gerasimenko was born.

Gerasimenko's name is well known because she was the co-discoverer of comet 67P/Churyumov–Gerasimenko. This was the comet explored by the Rosetta mission. Both the Rosetta spacecraft and the lander Philae are on the comet as it continues to orbit the Sun.
