433 Eros

433 Eros (ˈɪərɒs ) is the first discovered Near-Earth asteroid, named after the Greek god of love, Eros (Greek Ἔρως). It is an S-type asteroid approximately 34.4×11.2×11.2 km in size, the second-largest near-Earth asteroid (NEA) after 1036 Ganymed, belonging to the Amors. It is a Mars-crosser asteroid and was the first asteroid that was known to come within the orbit of Mars. Eros is one of the few NEAs with a maximum diameter greater than 10 km. It is believed to be larger than the impactor that created Chicxulub Crater in the Yucatán, which has been linked to the extinction of the dinosaurs
