C/2020 F3 (NEOWISE), or Comet NEOWISE, is a retrograde comet with a near-parabolic orbit discovered on March 27, 2020, by astronomers using the NEOWISE space telescope.

At that time it was a 10th magnitude comet, located 2 AU (300 million km; 190 million mi) away from the Sun and 1.7 AU (250 million km; 160 million mi) away from Earth.

The comet is notable for being one of the brightest visible to observers in the northern hemisphere since Comet Hale–Bopp in 1997.[1]
