Details
Eros is an elongated near-Earth asteroid explored by NASA’s NEAR Shoemaker mission. NEAR became the first spacecraft to orbit an asteroid and then survive a touchdown on one, turning Eros into a milestone in asteroid exploration.
NEAR Shoemaker entered orbit around Eros on 14 February 2000, becoming the first spacecraft to orbit an asteroid and spending a year mapping its shape, composition and gravity. On 12 February 2001, although it had not been designed as a lander, it made a controlled descent to the surface and continued transmitting for about two weeks.

About
Scale of Space is a scroll-based journey through the universe, placing objects on a single logarithmic scale so you can compare size across an unbroken range.
Guides explain selected parts of that range, while focused views filter the objects by subject.
