DESCRIPTION From APOD: Comet NEAT (Q4) is showing its tails. As the large snowball officially dubbed Comet C/2001 Q4 (NEAT) falls toward the inner Solar System, it has already passed the Earth and will reach its closest approach to the Sun this coming Saturday. Reports place the comet at third magnitude, making it easily visible to the unaided eye to northern sky gazers observing from a dark location just after sunset. Constellation: Cancer - Distance: .399422 AU RA: 08h 27m 10s - DEC: +15d 40m 34s - Magnitude: ~4.0 - Apparent Size: 2 degrees |
