(5535) Anne Frank Asteroid

Anne Frank is an asteroid, a large rock that orbits the Sun mainly between the orbits of Mars and Jupiter. They tend to be an irregular shaped but Ceres asteroid is known to be spherical in shape but because it doesn't clear its path round the Sun, it is only a dwarf planet.

Anne Frank was discovered on Mar 23 1942 by Karl Reinmuth. Its orbit takes 3.29 years to travel round the Sun.

The absolute magnitude of the object is 13.7 which is the brightness of the object. A higher absolute magnitude means that the object is faint whereas a very low number means it is very bright.

The Semi-Major Axis of the orbit is 2.212, which is the furthest point from the centre to the edge of an elliptical point.

The approximate diameter of Anne Frank is 8 km.

The orbital inclination, the angle at which Anne Frank orbits in relation to the orbital plane is 4.25 degrees. The orbital eccentricity is 0.643, it is the degree at which Anne Frank orbits close to a circular (0) orbit as opposed to an elliptical (1) orbit.

Annelies Frank, the inspiration for the name

AnneFrank asteroid was named after Annelies Marie "Anne" Frank, a Jewish teenager who wrote a diary of her experiences of hiding during the Second World War. With her family, she hid from the Nazi's in Amsterdam but as the War was coming to an end, her family were betrayed and she was transferred to Bergen-Belsen concentration camp. After the war, the diary posthumously published. The Asteroid was originally named 1942 EM but was renamed in her honour in 1995.

Path of Anne Frank Orbit

If the white lines are above, then the path of the object is under the ecliptic. If the white lines are below, the path is above the ecliptic. This refers to the Inclination of the object. The image was created using N.A.S.A. Solar System Dynamics.
