Asteroid 433, Eros.

¡@Planetary probes have landed on the moon, Venus, Mars and even one of Saturn's moons, Titan. On February 12, 2001, at the end of its mission, the US NEAR-Shoemaker probe soft-landed on the surface of Minor Planet 433 using its maneuvering jets. 433 was discovered on the same night (13 August 1898) by two unrelated astronomers. It was then named after the Greek god of love, Eros. Eros is the first discovered near-Earth asteroid (NEA). NEAs are objects that may come too close to the Earth, causing alarm. Measuring approximately 34.4¡Ñ11.2¡Ñ11.2 km, the second-largest near-Earth asteroid actually looks like a lonely potato drifting in the vastness of space. On January 31, 2012 Eros will fleet past Earth at a distance of just 0.179 astronomical unit, about 70 times the distance to the moon.¡@¡½ºÂªK±j¡@¸ê²`¤Ñ¤å·R¦nªÌ¡@¡@¡½¹Ï¤ù¨Ó·½¡GNASA/JPL/JHUAPL
