GREEN COMET APPROACHES EARTH: There's no danger of a collision.  However, a small green comet named "252P/LINEAR" is about to make one of the closest approaches to Earth of any comet in modern times, sailing just 5.4 million km from our planet on March 21st.  Moreover, the comet appears to have company: A possible fragment of 252P/LINEAR will fly by just one day later. A weak meteor shower could follow the double flyby near the end of March.
