C\/2020 F3 (NEOWISE)<\/b>, or\u00a0Comet NEOWISE<\/b>, is a\u00a0retrograde<\/a>\u00a0comet<\/a>\u00a0with a\u00a0near-parabolic<\/a>\u00a0orbit discovered on March 27, 2020, by astronomers using the\u00a0NEOWISE<\/a>\u00a0space telescope. At that time it was a 10th magnitude comet, located 2\u00a0AU<\/a>\u00a0(300\u00a0million\u00a0km<\/a>; 190\u00a0million\u00a0mi<\/a>) away from the Sun and 1.7\u00a0AU (250\u00a0million\u00a0km; 160\u00a0million\u00a0mi) away from Earth.[3]<\/a><\/sup><\/p>\n

By July 2020 it was bright enough to be visible to the\u00a0naked eye<\/a>. For observers in the\u00a0northern hemisphere<\/a>, in the morning the comet appears low on the northern-eastern horizon, below\u00a0Capella<\/a>. In the evening it can be seen in the north-western sky. In the second half of July 2020 it will appear to pass through the constellation of\u00a0Ursa Major<\/a>, below the\u00a0asterism<\/a>\u00a0of\u00a0The Plough<\/a>\u00a0(Big Dipper).<\/p>\n

The comet is notable for being one of the brightest visible to observers in the northern hemisphere since\u00a0Comet Hale\u2013Bopp<\/a>\u00a0in 1997.[4]<\/a><\/sup>\u00a0Under dark skies it can be clearly seen with the naked eye[5]<\/a><\/sup>\u00a0and is expected to remain visible to the naked eye throughout most of July 2020.[3]<\/a><\/sup><\/p>\n
