   Explanation: Get out your [6]red/blue glasses and float next to
   [7]asteroid 433 Eros. Orbiting the Sun once every 1.8 years, the
   near-Earth asteroid is named for the Greek god of love. Still, its
   shape more closely resembles a lumpy potato than a heart. Eros is a
   diminutive 40 x 14 x 14 kilometer world of undulating horizons,
   [8]craters, boulders and valleys. Its unsettling scale and unromantic
   shape are emphasized in [9]this mosaic of images from the NEAR
   Shoemaker spacecraft processed to yield a stereo anaglyphic view. Along
   with dramatic [10]chiaroscuro, NEAR Shoemaker's 3-D imaging provided
   important measurements of the asteroid's landforms and structures, and
   clues to the origin of this city-sized chunk of Solar System. The
   smallest features visible here are about 30 meters across. Beginning on
   February 14, 2000, historic NEAR Shoemaker spent a year in orbit around
   Eros, the first spacecraft to orbit an asteroid. Twenty years ago, on
   February 12 2001, it landed on Eros, the first ever landing on an
   asteroid's surface. [11]NEAR Shoemaker's final transmission from the
   surface of Eros was on [12]February 28, 2001.
