Stargazers will get a rare triple planetary treat in
November 2053, when Mercury, Mars, and Jupiter all lie
within a circle of less than one degree in diameter.
Recreational math circles will no less be celebrating the
fact that 2053#  1 is a primorial prime. The smallest prime reversal of a sphenic number s where the prime factors of s are a singledigit, a 2digit and a 3digit prime, i.e., 3502 = 2 × 17 × 103. [Loungrides]
