   Explanation: [5]Comet C/2023 E1 (ATLAS) was just spotted in March,
   another comet found by the NASA funded Asteroid Terrestrial-impact Last
   Alert System. On July 1 this Comet ATLAS reached perihelion, its
   closest approach to the Sun. Shortly afterwards the telescopic comet
   was [6]captured in this frame sporting a pretty greenish coma and
   faint, narrow ion tail against a background of stars in the far
   northern constellation Ursa Minor. This comet's closest approach to
   Earth is still to come though. On August 18 this [7]visitor to the
   inner Solar System will be a mere 3 light-minutes or so from our fair
   planet. [8]Based on its inclination to the ecliptic plane [9]and
   orbital period of about 85 years C/2023 E1 (ATLAS) is [10]considered a
   [11]Halley-type comet.
