Asteroid Flyby on Feb. 15

On Feb. 15th, an asteroid some 50 meters wide, neither very large nor very small, and is probably made of stone, as opposed to metal or ice will fly past Earth closer than many man-made satellites. Since regular sky surveys began in the 1990s, astronomers have never seen an object so big come so close to our planet.

  1. For a scientific community, where I’m used to standard measurement systems, why does everything have to resolve to football fields?

    I have absolutely no idea of the size of a football field or the volume of an olympic swimming pool. Please leave science to science and sport to the fanatics.

  2. hello nasa

    Whats the chance of this astroid bringing a new virus to earth, if debris from the astroid enter the earths atmosphere?
