Halley's Comet (that's easy, right?). Although it had been observed before, Halley was the first to discover that it was the same comet that returned at regular intervals, instead of a different object each time, and calculated its orbital period. There also exists a lunar crater named Halley.
Rosetta is not an astronaut; rather, it is a space probe launched by the European Space Agency (ESA) to study the comet 67P/Churyumov-Gerasimenko. Its mission was to gather detailed data about the comet's composition, structure, and activity as it approached the Sun. Rosetta made history by deploying the Philae lander, which successfully touched down on the comet's surface in 2014, marking the first time a spacecraft landed on a comet. The mission aimed to enhance our understanding of the early solar system and the formation of celestial bodies.
