While no meteorite has yet been observed to fall on the eleventh of February, the day is still important for meteorite studies as asteroid 357 Ninina was discovered on 11 February 1893.
On 11 February 1893 Asteroid 357 Ninina was discovered by Auguste Charlois at Paris.
357 Ninina always remains approximately within 460 and 490 million kilometers of the sun — somewhat closer to Mars than to Jupiter, but still very far away from either of them.
