Hamburga (minor planet designation : 449 Hamburga ) is a carbonaceous asteroid from the background population of the intermediate asteroid belt , approximately 75 kilometers in diameter. It 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.[3] [2]
449 was a proposed target for the 1980s-1990s space probe mission proposal CRAF.
Description
[ edit ]
Hamburga is classified as a C-type asteroid and is probably composed of carbonaceous material . It is named for the city of Hamburg in Germany.[3] Mathematical Society of Hamburg .[3]
449 Hamburga was identified as one of three asteroids that were likely to be a parent body for chondrites along with 304 Olga and 335 Roberta .[18] [18] [19] [19]
Proposed spacecraft visit
[ edit ]
In the 1980s and 1990s, NASA considered a spacecraft mission to the asteroid.[20] McDonald's chain of restaurants expressed an interest in sponsoring the mission, due to the accidental similarity of the asteroid's name to the food item "hamburger ", which was discussed in exploratory meetings between themselves and NASA.[21] [22]
In August 1988 in the United States' city of Baltimore, P. Weissman addressed the International Astronomical Union on a mission to this asteroid (449), a mission which also include a rendezvous with Comet Kopf .[23] Comet Rendezvous Asteroid Flyby for more on the mission to the comet. This mission can also be compared to Rosetta , which successfully flew by two minor planets and orbited a Comet during its approach to the Sun in the early 21st century. P. Weissman later worked on the Rosetta mission.[24]
Study
[ edit ]
It was predicted that 449 occulted the star HIP 1424 in July 2013.[25]
An asteroid occultation was predicted for 18 Oct 2018 with the magnitude 12 star UCAC4-557-042266.[26]
449 Hamburga has been observed to occult 15 stars between 1998 and 2023.
