A model of asteroid 433 Eros.
An S-type near earth asteroid, it was the first near earth asteroid discovered and currently the second largest NEA known, about 34.4×11.2×11.2 km in size.
It was visited by the NEAR shoemaker spacecraft twice in 1998 and 2000 which then terminated its mission in 2001 by landing on it. (despite not being designed to do so!)
1:500000 model is about 65mm across
1:400000 model is about 81.5mm across
1:200000 model is about 164.4mm across
1:100000 model is about 326mm across
