Comet Siding Spring set for a close encounter with Mars - epic meteor shower expected

C/2013 A1 (Siding Spring) is a long-period comet set for a very close encounter with Mars later this year. Although early estimates of its orbit showed a good possibility of impact, latest observations suggest a near miss and raise great concern for Mars
