A carbonaceous asteroid from the background population of the intermediate asteroid belt, approximately 75 kilometers in diameter. 449 Hamburga was discovered by German astronomers Max Wolf and Friedrich Schwassmann at Heidelberg Observatory on 31 October 1899, and later named after the city of Hamburg in Germany.
In the 1980s and 1990s, NASA considered a spacecraft mission to the asteroid. The mission plan called for a launch in 1995 and a flyby of Hamburga in early 1998. The McDonald’s chain of restaurants expressed an interest in sponsoring the mission, due the accidental similarity of the asteroid’s name to the food item “hamburger”, which was discussed in exploratory meetings between themselves and NASA; however, the spacecraft was eventually cancelled.
